Tracheostomy nursing: care, suctioning, and complications guide

Tracheostomy nursing is a foundational ICU and step-down skill. Patients with a tracheostomy cannot rely on their upper airway for protection, humidification, or communication — every one of those functions becomes a direct nursing responsibility. Managing a tracheostomy safely means understanding the tube anatomy, executing routine care without contamination, recognizing early complications, and knowing exactly what to do when the tube comes out unexpectedly.

This guide covers everything from tube types and step-by-step care to cuff management, Passy Muir valve (PMV) use, and emergency response — with 12–16 NCLEX-tested points flagged throughout.

What a tracheostomy is

A tracheostomy is a surgical opening made through the anterior neck into the trachea, typically between the second and fourth tracheal rings, to provide a direct airway. It is distinct from a laryngectomy (which removes the larynx entirely); most tracheostomy patients retain laryngeal function.

Surgical vs. percutaneous. Surgical tracheostomies are performed in the OR under general anesthesia. Percutaneous dilational tracheostomy (PDT) is performed at the bedside under bronchoscopic guidance using serial dilators — it is increasingly the standard approach in the ICU because it avoids an OR transfer. Both techniques produce a functionally equivalent stoma once healed.

Acute vs. chronic. An acute tracheostomy is placed to manage a short-term airway problem — prolonged mechanical ventilation, traumatic airway injury, post-surgical edema. A chronic tracheostomy is permanent or long-term, typically for patients with spinal cord injury, neuromuscular disease, or chronic ventilator dependence.

Common indications:

• Anticipated prolonged mechanical ventilation (typically >14–21 days on an ETT)
• Upper airway obstruction (tumor, trauma, angioedema, bilateral vocal cord paralysis)
• Inability to protect the airway (severe neurological injury, ALS, high cervical SCI)
• Failed extubation or expected extubation failure
• Facilitation of secretion management

Patients requiring a tracheostomy due to acute respiratory failure are covered in the acute respiratory failure nursing guide. Patients on long-term mechanical ventilation via tracheostomy are covered in the mechanical ventilation nursing guide.

Tracheostomy tube anatomy

Understanding tube components is prerequisite knowledge for safe care — you cannot troubleshoot obstruction, set cuff pressure correctly, or prepare for an emergency without knowing what each part does.

Tube sizing uses two numbers: inner diameter and length. Most adult patients use a #7 or #8 Shiley (or equivalent). Longer tubes (XLT — extra long trach) are used for patients with thick necks, obesity, or distorted anatomy. Pediatric tubes are sized differently — by age and weight, not standard adult sizing.

Tracheostomy care (step-by-step)

Tracheostomy care is performed every 8–12 hours and whenever soiled. It covers four distinct tasks: inner cannula care, stoma site care, dressing change, and tie/holder change. Each task carries its own contamination risk and technique requirements.

Inner cannula care

Disposable inner cannula (most common in acute care):

1. Perform hand hygiene; don gloves.
2. Remove the soiled inner cannula by rotating counterclockwise (or per manufacturer) and pulling straight out.
3. Discard into biohazard waste.
4. Insert a new, sterile inner cannula of the same size and model; rotate to lock.
5. Confirm 15mm adapter is secure before reconnecting to ventilator circuit.

Reusable inner cannula (common in long-term care and home settings):

1. Remove the inner cannula.
2. Clean with sterile water or normal saline (NS) using a small brush provided with the tube kit; do not use hydrogen peroxide on stoma tissue — it is cytotoxic and delays healing.
3. Rinse thoroughly; do not dry with cotton-tipped applicators (fibers can enter the airway).
4. Inspect lumen for residual secretion before reinsertion.
5. Reinsert and lock.

NCLEX tip: The dressing used at a tracheostomy stoma must be a non-cotton, lint-free split gauze (trach dressing). Standard cotton gauze sheds fibers that can be aspirated. Never cut a standard gauze pad to fit — use a manufactured split trach dressing.

Stoma site care

1. Using NS-moistened gauze or trach swabs, clean around the stoma in circular motions moving outward from the stoma (clean to dirty). Never clean directly into the stoma.
2. Assess skin integrity: erythema, maceration, excoriation, or granulation tissue. Document and escalate any signs of infection or breakdown. Guidance on wound assessment documentation is in the wound assessment guide.
3. Apply a clean, split trach dressing under the flange. Ensure the dressing is dry — moisture under the flange promotes skin breakdown and fungal colonization.
4. If secretions are copious or caustic, consider a hydrocolloid or foam border dressing per facility protocol.

Tie/holder changes

Trach ties (twill tape) or trach holders (Velcro) secure the tube in position. Ties must be changed when soiled, wet, or loose — but changing them carries a real risk of accidental decannulation.

Two-person technique (required for first 7–10 days post-placement):

1. One nurse holds the trach tube firmly in place throughout the entire procedure.
2. The second nurse removes and replaces the ties one side at a time.
3. New tie is threaded and secured before the old tie is fully removed.
4. Tightness check: Insert two fingers between the tie and the neck. The tie should allow two fingers to pass but not three. Too tight → skin breakdown; too loose → accidental decannulation risk.

After the stoma has matured (day 10+), a single competent nurse may change ties solo if the patient can cooperate; institutional policy varies.

Cuff management

The tracheostomy cuff seals the subglottic airway against aspiration and enables positive-pressure ventilation. It must be managed precisely.

Cuff pressure target: 20–30 cmH₂O. Check with a handheld manometer every 8–12 hours and after any position change, coughing episode, or suspected cuff issue. Many ICU ventilators also display cuff pressure continuously.

• <20 cmH₂O: Risk of microaspiration and VAP. Reinflate and recheck.
• >30 cmH₂O: Tracheal mucosal ischemia. The mucosa at this pressure has capillary perfusion pressure exceeded — prolonged overinflation leads to mucosal necrosis, ulceration, and tracheomalacia (softening of tracheal cartilage). Deflate immediately and recheck.

Cuff deflation is performed for speaking trials (PMV use), for patients eating/swallowing, and during certain suctioning protocols. Before deflating:

• Suction the oropharynx above the cuff first — there is always pooled secretion sitting on top of the cuff.
• Have suction ready.
• Confirm the patient can tolerate deflation (adequate respiratory effort, low aspiration risk).

Patients with a cuffless trach or a deflated cuff are able to direct airflow upward through the vocal cords — this enables phonation and, for tolerant patients, oral feeding.

Patients on mechanical ventilation in the ICU often have both a cuffed trach and complex ventilator management — the ARDS nursing guide covers the overlap with lung-protective ventilation settings.

Tracheostomy tube changes

First tube change: Performed by the physician or NP (not nursing) at 7–10 days post-placement. The stoma tract is immature before this point — the tissue has not fully granulated and formed a reliable channel. An accidental tube displacement before the tract is mature is a surgical airway emergency.

Subsequent tube changes: Can be performed by trained nursing staff per institutional protocol, typically every 30 days for chronic trach patients or more frequently if required.

Before every tube change:

• Confirm replacement tube (same size) is at bedside.
• Confirm backup tube (one size smaller) is at bedside in case the primary won’t advance.
• Confirm the obturator for both tubes is present and accounted for.
• Have bag-valve-mask with 100% O₂ ready.
• Position patient: pillow or shoulder roll to extend the neck and open the stoma angle.
• Pre-oxygenate if the patient is on supplemental O₂.

Procedure highlights:

1. Suction the trachea before removal.
2. Deflate the cuff; remove old tube with steady, curved motion following the tube’s natural angle.
3. Insert new tube with obturator in place; remove obturator immediately after the tube seats.
4. Inflate cuff; confirm bilateral breath sounds and ETCO₂ if available.
5. Secure ties; apply new dressing.

NCLEX tip: The obturator is used only during tube insertion, then removed immediately. It stays at the bedside — not inside the tube — during all normal patient care.

Humidification

The upper airway normally conditions inspired air to 37°C and 100% relative humidity before it reaches the carina. A tracheostomy completely bypasses this conditioning system. Delivering dry, cold gas directly to the trachea causes:

• Inspissation (drying and thickening) of secretions
• Mucociliary dysfunction
• Increased risk of mucus plugging and atelectasis

Heat-moisture exchangers (HME): Passive devices (“artificial noses”) attached to the 15mm adapter. They trap heat and moisture from exhaled breath and return it on the next inhalation. HMEs are inexpensive, single-use, and sufficient for most patients breathing spontaneously. They must be changed every 24 hours or when visibly soiled/wet.

HME contraindications: copious secretions, minute ventilation >10 L/min, body temperature <32°C (insufficient moisture in exhaled breath), and bronchopleural fistula.

Heated wire circuits: Used with mechanically ventilated patients and in those who cannot use an HME. An active heated humidifier with a heated wire inspiratory limb prevents rainout (condensation in the circuit tubing) while delivering fully conditioned gas.

Signs of inadequate humidification: secretions becoming progressively thicker, blood-tinged, or difficult to suction; increased suctioning frequency needed; patient reporting tracheal dryness or discomfort if able to communicate.

Communication

A tracheostomy interrupts the normal speech pathway — airflow no longer passes through the vocal cords on exhalation. Restoring communication is both a patient safety issue (patients cannot call for help) and a quality-of-life priority.

Passy Muir valve (PMV)

The PMV is a one-way speaking valve that attaches to the 15mm adapter of the tracheostomy tube. On inhalation, the valve opens and air enters through the trach. On exhalation, the valve closes — air cannot exit back through the trach and instead is redirected upward through the vocal cords and mouth, enabling speech.

PMV requirements — all must be met:

1. Cuff must be fully deflated. This is the single most important prerequisite. If the cuff is inflated, exhaled air cannot redirect upward — the patient will be unable to exhale and will build air pressure rapidly. This is life-threatening. The PMV is never placed on an inflated cuff.
2. No excessive or thick secretions — the secretion load must be manageable with regular suctioning; thick secretions compromise valve function and can cause obstruction.
3. Patent upper airway — air must be able to move through the larynx and oropharynx.
4. Patient tolerance — must be alert enough to cooperate, have adequate respiratory reserve, and not show signs of respiratory distress during the trial.

PMV trials are typically initiated by speech-language pathology (SLP) and supervised at the bedside. Nursing monitors respiratory rate, SpO₂, accessory muscle use, and patient comfort throughout.

Other communication strategies:

• Electrolarynx: Battery-powered device held to the neck; provides mechanical vibration for speech. Less natural sound but immediately usable.
• Writing boards or letter boards: Low-tech but reliable; essential backup when electronic options fail.
• Lip reading and mouthing words: Patient mouths words with cuff deflated; requires alert, cooperative patient and attentive staff.
• Augmentative and alternative communication (AAC) devices: Text-to-speech apps and eye-tracking systems for patients with severe neuromuscular limitations.

Ensure that every tracheostomy patient has a reliable communication method documented in the care plan — this is a patient safety requirement, not a comfort measure.

Proper infection control during all tracheostomy procedures, including glove donning and sterile field maintenance, is covered in the infection control and isolation precautions guide.

Complications to monitor

Emergency management

Accidental decannulation

Accidental decannulation is an airway emergency. Response must be immediate and protocol-driven.

Step-by-step response:

1. Call for help — activate rapid response or code team concurrently with your initial response.
2. Cover the stoma with a sterile gauze pad to prevent entrainment of air and foreign material.
3. Assess the patient — respiratory effort, SpO₂, level of consciousness.
4. Attempt reinsertion only if:
   • You are trained and competent in trach reinsertion
   • The stoma tract is mature (>7–10 days post-placement)
   • Insert new tube with obturator in place; remove obturator immediately; confirm breath sounds
5. If reinsertion fails or is not possible:
   • Apply bag-valve-mask over the stoma (not the mouth/nose in patients with permanent tracheostomy or laryngectomy — the stoma IS the airway)
   • For patients with laryngectomy, all ventilation is via the stoma only
   • Prepare for emergency surgical airway management
6. Prevent in the first place: Replacement tube (same size) and one-size-smaller backup tube, both with their obturators, must be taped to the head of bed at all times.

Tube obstruction

1. Attempt to pass a suction catheter — if you cannot advance it, the tube is obstructed.
2. Remove and inspect/replace the inner cannula immediately.
3. Attempt suctioning again with a fresh catheter.
4. If obstruction persists, instill 3–5 mL sterile NS to loosen secretions and reattempt.
5. If still obstructed → tube change (physician or experienced RN per protocol) — do not delay.
6. Bag-valve-mask the patient via the trach while preparing for tube change if they are deteriorating.

Signs of respiratory distress requiring immediate intervention

Tachypnea (RR >30), SpO₂ <90% despite O₂, use of accessory muscles, paradoxical chest movement, stridor, agitation or altered mental status in a previously alert patient, and rising peak airway pressures on the ventilator all require immediate assessment.

For respiratory distress assessment and management in the context of critical illness, see the head-to-toe assessment guide.

NCLEX tips for tracheostomy nursing

The following points are consistently tested on NCLEX. Each represents a concept where the wrong answer choice is plausible, making clinical clarity essential.

• PMV requires a deflated cuff. If the cuff is inflated with a PMV in place, the patient cannot exhale — this causes air trapping and is life-threatening. The deflated cuff is a hard requirement, not a preference.
• The obturator stays at the bedside, not inside the tube. The obturator occludes the tube lumen. It is used only during insertion (insertion guide), then removed immediately. Its job is reinsertion readiness, not permanent residence.
• Suction maximum 10 seconds per pass. Prolonged suctioning causes hypoxia, mucosal trauma, and vagally-mediated bradycardia. Each catheter pass is ≤10 seconds. Multiple passes are separated by allowing the patient to recover (at least 30–60 seconds, or until SpO₂ recovers).
• Pre-oxygenate with 100% O₂ before suctioning. Hyperventilate with 100% O₂ via manual resuscitation bag or ventilator hyperoxygenation setting before each suction pass to reduce hypoxia risk.
• Do not suction deeper than the distal end of the tube. Catheter depth should equal the tube length, not beyond. Passing the catheter beyond the distal tip contacts the carina, causing intense coughing, mucosal trauma, and increased risk of bronchospasm.
• First tracheostomy tube change is physician or NP — not nursing. The stoma tract is immature for 7–10 days; early tube dislodgement without a mature tract is a surgical emergency. Nurses do not perform the first change.
• Use non-cotton, lint-free split trach dressings. Standard cotton gauze (including cut gauze) sheds fibers that can be aspirated. Only manufactured split trach dressings are safe at the stoma.
• Two-finger rule for tie tightness. The tie should allow two fingers to pass but not three. Too tight → pressure injury; too loose → decannulation risk.
• Cuff pressure target: 20–30 cmH₂O. Below 20 = microaspiration and VAP risk. Above 30 = tracheal mucosal ischemia → tracheomalacia.
• Cuff pressure >30 cmH₂O causes tracheal mucosal ischemia. The capillary perfusion pressure of tracheal mucosa is approximately 25–30 cmH₂O; pressures above this occlude capillary flow and cause ischemic necrosis.
• Accidental decannulation: cover stoma, reinsert if trained, bag-mask via stoma if not. The response sequence matters on NCLEX. Do not ventilate via mouth/nose if a stoma is present — the stoma is the airway.
• Fenestrated tube inner cannula must be in during suctioning. The fenestration in the outer cannula opens into tracheal tissue, not the airway lumen. If you suction with the fenestrated inner cannula out (or no inner cannula), the catheter can enter the fenestration and contact the tracheal wall, causing trauma.
• Humidification is mandatory with a tracheostomy. The upper airway no longer conditions inspired gas. Without HME or active humidification, secretions inspissate and mucus plugging occurs.
• Subcutaneous emphysema (crepitus around stoma) → notify physician immediately. This indicates air tracking into soft tissues and can signal tube displacement or tracheal injury.
• TEF presentation: tube feeds appearing in tracheal secretions. Gastric contents bypassing the esophagus into the trachea via a fistula. Stop feeds immediately and notify.
• Two-person tie change is required for the first 7–10 days. Before the stoma matures, single-nurse tie changes carry an unacceptable decannulation risk.
