Airway management nursing: assessment, adjuncts, and intubation support

Airway management is the single most time-critical skill in acute care nursing. When a patient loses their airway — whether from altered consciousness, anaphylaxis, secretion accumulation, trauma, or respiratory failure — the window for intervention is measured in minutes. No other nursing skill demands a more systematic, practiced response. The nurse who can assess airway patency, position a patient correctly, insert an adjunct, pre-oxygenate before rapid sequence intubation, and confirm tube placement after intubation is the nurse who prevents cardiac arrest and brain injury.

This guide covers the full airway management skill set: anatomy relevant to practice, systematic assessment using the look-listen-feel approach, positioning techniques, oropharyngeal and nasopharyngeal adjuncts, oxygen delivery devices, endotracheal intubation support from pre-oxygenation through cuff management, complications, extubation readiness assessment, and 20 NCLEX high-yield tips. Clinical accuracy is the standard — every dose, pressure range, and threshold listed here reflects current evidence and established nursing practice guidelines.

Quick-reference summary

Airway anatomy relevant to nursing

Understanding which structures can obstruct the airway — and why — is what separates assessment from guesswork.

Upper airway

The upper airway begins at the nose and mouth. Air enters through the nasal cavity (which warms, humidifies, and filters it) or the oral cavity. Both converge at the nasopharynx and oropharynx — the regions behind the nose and mouth respectively, collectively called the pharynx. The pharynx ends at the larynx, the cartilaginous structure that protects the lower airway.

Within the larynx, two structures are critical to nursing practice:

• Epiglottis: a leaf-shaped flap of cartilage that covers the glottis during swallowing, preventing aspiration. In the unconscious patient or during laryngoscopy, the epiglottis is the landmark the provider lifts to visualize the vocal cords.
• Vocal cords (glottis): the opening through which air passes into the trachea. An endotracheal tube passes between the vocal cords. Cords that are closed (laryngospasm) completely block airflow.

The most common cause of upper airway obstruction in the unconscious patient is the tongue. As muscle tone is lost, the tongue falls posteriorly against the posterior pharyngeal wall, blocking airflow. This is why head-tilt–chin-lift and jaw thrust — both of which lift the tongue forward — are first-line interventions before any adjunct or device.

Other upper airway obstructors: secretions or vomit pooling in the pharynx, angioedema, epiglottitis, foreign body, and edema from burns or anaphylaxis.

Lower airway

Below the larynx, the trachea descends approximately 10–12 cm in adults before bifurcating at the carina into the left and right mainstem bronchi. The right mainstem bronchus is shorter, wider, and branches at a less acute angle (~25°) than the left (~40–45°). This anatomy explains two important clinical phenomena:

1. Foreign bodies preferentially lodge in the right mainstem bronchus — gravity and geometry favor it.
2. Endotracheal tubes advanced too far migrate into the right mainstem — cutting off left lung ventilation. This is one of the most common intubation errors and is detected by absent breath sounds on the left.

A correctly positioned ETT tip sits 2–4 cm above the carina, verified on chest X-ray.

Airway assessment

Airway assessment is structured around three senses: look, listen, feel. It takes under 30 seconds but must be deliberate. Missing a compromised airway because assessment was skipped is the most preventable airway emergency.

Look

• Chest rise: symmetrical, adequate depth? Paradoxical movement (in on inspiration) suggests flail segment or complete obstruction.
• Work of breathing: accessory muscle use (sternocleidomastoid, scalene muscles pulling upward on inspiration), nasal flaring, intercostal retractions, tracheal tug (downward displacement of the trachea on inspiration).
• Color: central cyanosis (circumoral, tongue, mucous membranes) is a late and serious sign of hypoxia. Peripheral cyanosis is less specific.
• Consciousness level: GCS is the single most important airway protection predictor. A GCS ≤8 means the patient cannot reliably protect their airway — intubation is a clinical consideration, not a reflex, but this is the threshold that triggers urgent assessment and preparation.
• Body position: a tripod position (sitting forward, hands on knees, neck extended) indicates severe respiratory distress.

Listen

• Stridor: high-pitched inspiratory sound, indicates partial upper airway obstruction at or above the larynx. Stridor is a pre-arrest sound — the airway is narrowed; complete obstruction can follow rapidly.
• Snoring (stertor): low-pitched inspiratory sound, indicates partial pharyngeal obstruction — most commonly the tongue. Responds well to positioning and adjuncts.
• Gurgling: fluid in the pharynx — secretions, blood, vomit. Requires immediate suctioning before any other intervention. A gurgling patient will aspirate.
• Silence with absent chest rise: complete obstruction. No air movement. Treat as an emergency.
• Wheeze: lower airway obstruction (bronchospasm, mucus, foreign body below the cords). Inspiratory and expiratory wheeze suggests severe bronchospasm.
• Crackles: fluid in alveoli or small airways — pulmonary edema, pneumonia. Doesn’t indicate obstruction of the upper airway but does indicate impaired gas exchange.

Feel

• Air movement at mouth or nose: on exhalation, feel for warm air flow with the dorsum of your hand. Absent air flow confirms obstruction or apnea.
• Tracheal position: midline or deviated? Tension pneumothorax causes tracheal deviation away from the affected side (late sign).
• Neck and chest compliance: feel the chest rise with each breath. Unilateral absence of movement in an intubated patient suggests tube migration or pneumothorax.

SpO₂ and its limits

SpO₂ monitoring is essential but lags behind clinical deterioration. A patient who is pre-oxygenated or has a high hemoglobin can maintain SpO₂ >90% for minutes after apnea begins. Conversely, low perfusion states, peripheral vasoconstriction, nail polish, and motion artifact all produce unreliable readings. Use SpO₂ as one data point within the full clinical picture — never the sole airway assessment tool.

LEMON assessment for difficult airway

Before intubation, any nurse assisting should be aware of difficult airway predictors. The LEMON mnemonic guides rapid assessment:

• L — Look externally: obesity, short neck, large tongue, trauma, beard, micrognathia, protruding incisors, morbid obesity
• E — Evaluate the 3-3-2 rule:
  • 3 fingers fit between upper and lower incisors (mouth opening)
  • 3 fingers fit between chin and hyoid bone (thyromental distance — mandibular space for tongue displacement)
  • 2 fingers fit between hyoid bone and thyroid notch (laryngeal position)
  • Any measurement falling short predicts difficult laryngoscopy
• M — Mallampati classification: patient sits upright, opens mouth fully, extends tongue without phonating. Class I–II (uvula/faucial pillars visible) = easy; Class III–IV (soft palate only, or only hard palate) = potentially difficult
• O — Obstruction: any condition obstructing the airway (epiglottitis, peritonsillar abscess, hematoma, angioedema, tumor)
• N — Neck mobility: cervical spine injury, ankylosing spondylitis, or severe osteoarthritis all reduce neck mobility and complicate laryngoscopy

Positioning techniques

Correct positioning opens the upper airway and reduces obstruction — without equipment and without delay.

Head-tilt–chin-lift

The default airway-opening technique for patients without suspected cervical spine injury. Place one hand on the forehead and apply firm backward pressure to extend the neck. Place the fingertips of the other hand under the bony chin (not the soft tissue) and lift forward. This extends the atlantooccipital joint, stretches the anterior neck structures, and lifts the tongue away from the posterior pharyngeal wall.

When to use: any unconscious or obtunded patient without known or suspected C-spine injury — cardiac arrest, drug overdose, post-ictal state, metabolic encephalopathy.

When not to use: confirmed or suspected cervical spine injury (trauma mechanism). Use jaw thrust instead.

Jaw thrust

The jaw thrust opens the airway without extending the cervical spine. Place hands on either side of the patient’s head, position fingertips behind the mandibular angle, and apply upward and forward pressure to displace the jaw anteriorly. The thumbs may rest on the chin.

When to use: suspected cervical spine injury (fall, motor vehicle collision, diving accident, any trauma mechanism until C-spine cleared).

Limitation: requires more effort to maintain than head-tilt–chin-lift, especially during BVM ventilation. A two-person technique — one maintaining jaw thrust, one squeezing the bag — is preferred. See bag-valve-mask ventilation for BVM positioning details.

Sniffing position for intubation

The optimal intubation position aligns three axes: the oral, pharyngeal, and laryngeal axes. The sniffing position achieves this by:

• Flexing the neck at the cervical spine (bring chin toward chest slightly — not hyperflexion)
• Extending the head at the atlantooccipital joint (tilt the head back)

The clinical landmark for correct sniffing position is ear-to-sternal-notch alignment: looking from the side, the patient’s ear canal opening and their sternal notch should be at the same horizontal level. In obese patients, this typically requires significant head-of-bed elevation or ramping with blankets under the torso and head.

Incorrect positioning — head flat on the bed, no neck flexion — dramatically worsens the laryngoscopic view. Positioning is not a minor detail; studies consistently show it changes view grade by 1–2 Cormack-Lehane grades.

Airway adjuncts

Adjuncts physically hold the airway open, removing the nurse’s hands from the equation and freeing attention for other tasks.

Oropharyngeal airway (OPA)

The OPA is a curved rigid or semi-rigid device that sits between the tongue and the posterior pharyngeal wall, holding the tongue forward. It does not protect against aspiration and does not ventilate — it simply maintains a patent passage for airflow or BVM mask ventilation.

Sizing: Measure from the center of the mouth (corner of the lips) to the tip of the earlobe — or alternatively, from the center of the incisors to the angle of the jaw. Place the device next to the patient’s face: the flange should rest at the lips when the tip reaches the earlobe. Common adult sizes: 80 mm (size 3), 90 mm (size 4), 100 mm (size 5).

An OPA that is too small will push the tongue back rather than lift it, worsening obstruction. One that is too large will stimulate the larynx or fold the epiglottis down over the glottis — both dangerous.

Insertion technique — adults: Insert the OPA upside down (curve pointing toward the palate / ceiling) and advance until resistance is felt at the posterior pharynx, then rotate 180° so the curve faces down and the flange rests at the lips. The rotation maneuver avoids pushing the tongue posteriorly during insertion.

Alternative insertion technique (tongue depressor method): Use a tongue depressor to hold the tongue down and forward, then insert the OPA directly with the curve facing downward — no rotation needed. This is preferred in pediatric patients (to avoid injury to the soft palate during rotation).

Contraindications:

• Conscious or semi-conscious patient with an intact gag reflex — will trigger vomiting, laryngospasm, and potentially aspiration. Never insert an OPA unless the patient tolerates it without gagging.
• Active bleeding in the mouth (relative)
• Recent oral surgery (relative)

When the OPA is preferred: deeply unconscious patients (GCS very low, no gag reflex), in-cardiac-arrest patients, and as an adjunct during BVM ventilation to improve mask seal and reduce air leak.

Nasopharyngeal airway (NPA)

The NPA is a soft, flexible rubber or latex tube inserted through a nostril and positioned in the nasopharynx, just above the epiglottis. It maintains a passage behind the base of the tongue without triggering the gag reflex — which makes it the adjunct of choice for semi-conscious patients.

Sizing: Measure from the tip of the nose to the earlobe — this estimates the distance from nostril to nasopharynx. Select a diameter that approximates the patient’s naris — a tube that is too narrow provides minimal benefit; one that is too wide causes mucosal trauma and epistaxis. Most adult females use a 6–7 mm internal diameter NPA; most adult males use a 7–8 mm.

Insertion technique: Apply generous water-soluble lubricant to the entire outer surface of the NPA. Insert into the right nostril (bevel facing toward the nasal septum — the flat side should slide against the septum to reduce trauma). Advance gently with a slight twisting motion, following the floor of the nasal cavity (not angling upward). The flange should rest at the naris when correctly positioned. If resistance is felt, do not force — try the left nostril or a smaller size.

Contraindications:

• Suspected basilar skull fracture — the NPA could pass intracranially through the fracture. Signs of basilar skull fracture: Battle’s sign (retroauricular ecchymosis), raccoon eyes (periorbital ecchymosis), hemotympanum, CSF rhinorrhea or otorrhea.
• Severe coagulopathy or anticoagulation (significant epistaxis risk)
• Known nasal polyps or nasal obstruction
• Recent nasal or skull base surgery

When the NPA is preferred: semi-conscious patients with intact gag reflex who cannot tolerate an OPA, patients with trismus (lockjaw) where the mouth cannot open, and any patient where an OPA is contraindicated but airway support is needed.

Oxygen delivery devices

Selecting the correct oxygen device depends on the patient’s FiO₂ requirement, their ability to cooperate, and whether precise oxygen control is needed. The following table summarizes the devices most commonly used in airway management.

See oxygen therapy nursing for a full guide to oxygen delivery across all settings.

BVM ventilation

When a patient is apneic or has inadequate spontaneous ventilation, BVM ventilation bridges the gap until the airway is secured or spontaneous breathing resumes. Target tidal volume is 6–8 mL/kg ideal body weight at a rate of 10–12 breaths per minute in adults. A two-person technique — one maintaining airway positioning and mask seal (E-C clamp), one squeezing the bag — delivers significantly superior tidal volumes compared to single-operator technique and should be used whenever a second provider is available.

See bag-valve-mask ventilation for the full guide including mask sizing, technique, and pediatric considerations.

Endotracheal intubation — nursing role

Endotracheal intubation places a cuffed tube through the vocal cords into the trachea, providing a definitive, protected airway. The nurse does not perform the laryngoscopy, but the nurse’s preparation, medication management, monitoring, and post-intubation care directly determine the outcome. A disorganized nursing setup is a significant contributor to intubation complications and failed attempts.

Pre-intubation checklist: SOAPME

RSI nursing support

Rapid sequence intubation (RSI) is the standard approach for emergency intubation in patients at risk of aspiration. The defining feature of RSI is the simultaneous administration of a sedative induction agent and a neuromuscular blocking agent (paralytic), followed immediately by laryngoscopy — with no bag-mask ventilation interval, to minimize aspiration risk.

Pre-oxygenation (3–5 minutes before drugs):

• Position NRB at 15 L/min. Coach the patient to take slow deep breaths if cooperative.
• If the patient cannot maintain SpO₂ with NRB, apply BVM at low pressure with PEEP valve if available.
• HFNC at 60 L/min continued through the apneic period provides apneic oxygenation — passive O₂ delivery down the airway concentration gradient, extending safe apnea time by 2–5 minutes. Studies support leaving HFNC in place during laryngoscopy.

Medication sequence — prepare and label all medications before administration. Draw up, cap, and label each syringe:

1. Induction agent (sedative) — produces unconsciousness in one arm-brain circulation time (~20–30 seconds):

   • Etomidate: 0.3 mg/kg IV push. Advantages: cardiovascular stability, minimal hemodynamic change. Disadvantage: transient adrenal suppression (single dose in RSI context is acceptable per most guidelines). Most common RSI induction agent.
   • Ketamine: 1–2 mg/kg IV push. Advantages: maintains hemodynamic stability via sympathomimetic effect, bronchodilatory (preferred in reactive airway disease), analgesic. Disadvantage: increases secretions (consider glycopyrrolate pre-treatment), dissociative emergence (manage with benzodiazepines). Preferred in hypotensive or asthmatic patients.
   • Propofol (less common for RSI): 1.5–2 mg/kg IV push. Causes significant hypotension — avoid in hemodynamically unstable patients.

2. Neuromuscular blocking agent (paralytic) — administered immediately after or simultaneously with induction agent:

   • Succinylcholine: 1–1.5 mg/kg IV push (depolarizing agent, ultra-short-acting, onset 45–60 seconds, duration 8–10 minutes). Contraindicated with hyperkalemia, burns >24–48 hours old, crush injuries, neuromuscular disease, personal/family history of malignant hyperthermia, denervation injuries.
   • Rocuronium: 1.2 mg/kg IV push for RSI dosing (non-depolarizing, onset comparable to succinylcholine at this dose, duration 60–90 minutes). Reversal agent available: sugammadex 16 mg/kg IV. Preferred when succinylcholine is contraindicated.

Cricoid pressure (Sellick maneuver): Firm downward pressure on the cricoid cartilage compresses the esophagus against the vertebral body, theoretically preventing passive regurgitation. Its use is now controversial — evidence does not consistently show reduced aspiration risk, and it can worsen the laryngoscopic view. Apply only if the intubating provider specifically requests it, and release immediately if the view is impaired.

Nurse’s role during RSI:

• Draw up medications before the procedure begins
• Administer medications on provider’s instruction in correct sequence and dose
• Maintain SpO₂ monitoring throughout — call out declining SpO₂
• Apply cricoid pressure if requested; release immediately if asked or if view impaired
• Hand equipment to provider on request (tube, stylet, syringe)
• Time from drug administration to laryngoscopy and note any desaturation

Post-intubation confirmation

Confirming tube placement immediately after intubation is a time-critical nursing responsibility. Unrecognized esophageal intubation is fatal.

Documentation after confirmation: Record the cm marking at the lip or teeth (typically 21–23 cm at lip in adult females, 23–25 cm in adult males), the tube size, the confirmation methods used, and the time of intubation. Any change in tube position requires re-documentation.

Tube securing

An unsecured ETT can self-extubate in seconds. Two methods are in common use:

• Commercial ETT holder (Thomas Hold, Endotracheal Tube Holder): purpose-made device with bite block, locks tube in place, less likely to cause skin breakdown than tape. Preferred by many ICUs.
• Tape: cloth tape applied from one cheek across the tube at lip level and to the other cheek, with a split piece wrapped around the tube in opposite directions. Secure to the face, not only the tube. Change tape when wet or loose; wet tape provides no security.

Verify cm marking at lip/teeth at every assessment and after any repositioning.

Cuff management

The ETT cuff seals the space between the tube and the tracheal wall. Its dual functions are:

1. Preventing aspiration: oral/gastric secretions that pool above the cuff cannot pass into the lungs if the cuff is properly inflated.
2. Enabling ventilation: an inadequate cuff seal causes gas to leak, reducing tidal volume delivery and causing audible air leak during ventilation.

Cuff pressure target: 20–30 cmH₂O (approximately 15–25 mmHg). This range:

• Exceeds tracheal perfusion pressure at the low end (preventing capillary occlusion and ischemic injury)
• Does not exceed tracheal mucosa capillary pressure at the high end (preventing mucosal necrosis and tracheomalacia)

Cuff manometer: a handheld manometer is the only accurate way to measure cuff pressure. Palpating the pilot balloon by hand is unreliable. Check cuff pressure every 8 hours or with any concern about seal or leak. Add or remove air with a 10 mL syringe on the pilot balloon port until the manometer reads 20–30 cmH₂O.

Post-intubation care

Once the tube is confirmed and secured, the nursing care bundle for intubated patients begins. This is ventilator-associated pneumonia (VAP) prevention in action:

• HOB ≥30° (ideally 30–45°): reduces aspiration of subglottic secretions. One of the most evidence-based VAP prevention measures. Document HOB angle at every assessment.
• Oral care with chlorhexidine 0.12%: reduces oropharyngeal bacterial colonization. Apply via swab every 2–4 hours. Part of every ICU VAP bundle. See oral care nursing for technique.
• Subglottic secretion suctioning: specialized ETTs with a lumen above the cuff (continuous aspiration of subglottic secretions — CASS tubes) allow continuous or intermittent suctioning of the pool that forms above the cuff and below the vocal cords. Meta-analysis data supports CASS tubes reducing VAP rates by ~45%.
• Sedation and analgesia monitoring: use validated scales — RASS (Richmond Agitation-Sedation Scale) for sedation depth (target typically RASS 0 to -2 for mechanically ventilated patients), CPOT (Critical Care Pain Observation Tool) for pain in non-verbal patients. Daily sedation interruption (“wake-up trials”) reduces total sedation exposure and ventilator days.
• Tube position re-verification: confirm cm marking at lip after any patient repositioning, transport, or any procedure that may move the tube.
• Inline suctioning: airway suctioning nursing covers closed-circuit suctioning of the intubated patient. Suction as clinically indicated — not on a fixed schedule.

For ongoing ventilator management after intubation, see mechanical ventilation nursing.

Complications

Esophageal intubation

The most immediately life-threatening intubation complication. The ETT enters the esophagus rather than the trachea. The patient receives no ventilation.

Signs: absent waveform on capnography (most reliable), epigastric sounds on auscultation, absent bilateral breath sounds, absent condensation in the ETT during exhalation, SpO₂ declining rapidly, no chest rise.

Action: immediate extubation — remove the tube. Ventilate with BVM. Allow SpO₂ to recover before re-attempting intubation. Capnography waveform is the single most important detection tool — if there is no waveform after 6 breaths, the tube is out of the trachea until proven otherwise.

Right mainstem intubation

An ETT advanced too far migrates into the right mainstem bronchus, ventilating only the right lung.

Signs: absent or significantly diminished breath sounds on the left, unilateral (right-sided) chest rise, SpO₂ may remain adequate initially, CXR shows ETT tip at or below the carina.

Action: withdraw the ETT 1–2 cm at the lip, re-assess breath sounds bilaterally, confirm bilateral chest rise, re-check cm marking, obtain CXR. Prevention: confirm cm marking is within expected range (21–23 cm at lip in adult females, 23–25 cm in adult males) immediately after intubation.

Inadvertent extubation

Self-extubation is a significant risk, particularly in agitated patients. Consequences range from successful re-intubation to respiratory arrest.

Prevention: secure the tube correctly at all times, reassess tube security with every patient contact, consider soft wrist restraints per institutional protocol for patients who are pulling at lines/tubes (requires provider order and documented assessment), optimize sedation to prevent agitation while minimizing over-sedation.

Action on self-extubation: call for help immediately, position the patient, apply BVM ventilation, initiate oral care/suction, notify the provider for re-intubation.

Cuff leak

An audible leak during mechanical ventilation — air escaping around the ETT cuff on each delivered breath — indicates inadequate cuff seal.

Causes: cuff underinflation, cuff rupture (rare), pilot balloon valve failure, ETT too small for the trachea.

Action: check cuff pressure with manometer; add air in 0.5 mL increments until pressure is 20–30 cmH₂O; if pilot balloon does not hold pressure (rapid deflation), the cuff has a hole — notify provider; plan for tube change.

Caution: do not blindly inflate the cuff to stop a leak without using a manometer. Over-inflation (>30 cmH₂O) causes tracheal ischemia.

Subglottic secretion accumulation

Secretions pool above the cuff and below the vocal cords. This pool is inaccessible to standard suctioning through the ETT. It is the primary source material for microaspiration past the cuff that causes VAP.

Management: use CASS-capable ETTs when prolonged intubation is anticipated; perform subglottic suctioning every 4–8 hours if CASS tube is in place; maintain cuff pressure within 20–30 cmH₂O range to minimize microaspiration past the cuff seal; maintain HOB ≥30°.

Supraglottic airways — nursing awareness

Supraglottic airways (SGAs) sit above the glottis and do not enter the trachea. They are not definitive airway management but serve as rescue devices and planned airway alternatives for selected procedures.

Laryngeal mask airway (LMA): a silicone mask that seats in the hypopharynx over the glottis, with an inflatable rim. Used in operating room anesthesia, failed-intubation rescue protocols, and CPR scenarios. Provides reasonable ventilation without a laryngoscope but does not protect reliably against aspiration.

King LT (laryngeal tube): a blind-insertion device placed into the esophagus; two balloons (pharyngeal and esophageal) seal above and below the ventilation ports, directing gas into the trachea. Commonly used by emergency medical services and in cardiac arrest protocols.

Nursing role: nurses do not insert SGAs in standard practice unless trained and credentialed to do so (some ICU and flight nurses are). The nursing role is to assist the provider, monitor the patient during SGA use, recognize when the SGA is not providing adequate ventilation (persistent low SpO₂, significant leak), and anticipate the need for conversion to ETT.

When a patient with an SGA in place requires definitive airway management, alert the provider immediately — SGAs are bridges, not endpoints. See tracheostomy nursing for the surgical airway option when intubation fails.

Extubation readiness assessment

Nurses play a central monitoring role in extubation readiness — both during spontaneous breathing trials and in post-extubation assessment. The goal is to identify patients ready for extubation before prolonged unnecessary intubation causes its own complications (VAP, subglottic injury, ICU delirium from immobility and sedation).

Spontaneous breathing trial (SBT)

The SBT reduces ventilatory support to minimal levels (pressure support ventilation 5–8 cmH₂O, PEEP 5 cmH₂O, or T-piece) for 30–120 minutes while the nurse monitors for failure signs. Failure criteria: RR >35, SpO₂ <90% on FiO₂ ≤40%, HR or BP change >20% from baseline, increased work of breathing, agitation or altered consciousness.

RSBI (Rapid Shallow Breathing Index): calculated as respiratory rate (f) divided by tidal volume in liters (VT). RSBI = f/VT.

• RSBI <105 predicts successful extubation in most patients
• RSBI >105 predicts failure — the patient is breathing rapidly with inadequate depth, suggesting respiratory muscle fatigue

The RSBI is a widely used, evidence-based clinical tool. It is calculated at the beginning of the SBT with minimal support. A low RSBI alone does not guarantee extubation success — it must be considered alongside the full clinical picture.

Clinical readiness criteria

• Alert and following commands (GCS adequate)
• Adequate cough and gag — can mobilize secretions and protect the airway
• Secretion burden manageable — not requiring suctioning more frequently than every 2 hours
• FiO₂ ≤40%, PEEP ≤5 cmH₂O with SpO₂ ≥90%
• Hemodynamically stable (not on escalating vasopressors)
• Cause of intubation reversed or improving

Cuff leak test

With the cuff deflated, an audible leak of air around the tube on positive pressure breath indicates that the subglottic space is patent. No audible leak (failed cuff leak test) suggests supraglottic edema — post-extubation stridor is likely. Providers may delay extubation and administer dexamethasone (0.5 mg/kg IV q6h × 4 doses) to reduce edema, then re-test.

Post-extubation monitoring

After extubation:

• Monitor for stridor — indicates laryngeal edema. Mild: cool mist, repositioning. Severe: heliox, racemic epinephrine, or emergency re-intubation.
• Maintain SpO₂ monitoring continuously for at least 1 hour
• Step-down oxygen: HFNC or non-invasive ventilation (NIV) as bridge; evidence supports HFNC post-extubation reduces re-intubation rates in high-risk patients
• Reintubation triggers: SpO₂ <90% on supplemental O₂, RR >35, acute hemodynamic deterioration, loss of airway protective reflexes, GCS decline

Patient and family communication

Communicating with conscious patients before intubation

When a patient is awake and deteriorating, the nurse often has the role of explaining what is about to happen while the team prepares. Keep communication calm, directive, and brief:

• “We’re going to help you breathe. The doctor is going to put a tube down your throat to do that. It will be uncomfortable, but we’re going to give you medicine so you won’t feel it.”
• Reassure that the patient will not be able to speak with the tube in, but will not be in pain.
• If there is any time: address the patient’s questions, confirm allergies, confirm any advance directives.

Family communication during emergency intubation

Family members witnessing emergency intubation experience significant distress. When possible, a nurse should be assigned to stay with the family outside the room to explain what is happening in plain language, answer questions, and update them as soon as the procedure is complete.

Post-intubation, explain:

• Why the tube was placed and what it is doing
• That the patient cannot talk but can hear
• What the machines do
• What will happen next
• How to communicate with an intubated patient (gestures, head nods, letter/number boards, dry-erase boards)

Interpreter services

For non-English-speaking patients or families: engage professional medical interpreter services — in-person, video, or telephone. Do not use family members as interpreters for medical decisions. This is a patient rights issue, not a convenience option.

Communication with intubated patients

Intubated patients are isolated from verbal communication. Nursing care includes:

• Orient the patient frequently — explain where they are, what the tube is, what will happen
• Use yes/no questions with head nods
• Provide letter boards, tablet apps, or dry-erase boards for cooperative patients
• For patients with a tracheostomy and a compatible tube, a Passy Muir speaking valve (PMV) allows phonation — see tracheostomy nursing for detail
