Tracheostomy Care: Routine Management, Suctioning Technique, and Emergency Response

A tracheostomy is a surgically created opening in the anterior trachea (typically between the 2nd and 4th tracheal rings) through which a tracheostomy tube is inserted to provide a direct airway. The tube bypasses the upper airway — nose, mouth, pharynx, and larynx — which means the patient breathes through the tube, not through their mouth and nose. The tracheostomy tube has three main components. The outer cannula is the main body of the tube — it sits in the stoma (the opening in the trachea) and is secured in place with ties or a Velcro holder around the neck. The inner cannula is a removable or disposable insert that fits inside the outer cannula. Its purpose: secretions accumulate on the inner surface of the tube, and the inner cannula can be removed, cleaned, and reinserted (or replaced with a new disposable one) without disturbing the outer cannula. This is the maintenance access point. The obturator is a blunt-tipped insert used only during tube insertion — it smooths the end of the tube for atraumatic passage through the stoma. The obturator is removed immediately after insertion and replaced with the inner cannula. Keep the obturator taped to the head of the bed at all times — it is needed if the tube is accidentally dislodged and must be reinserted. Cuffed vs uncuffed tubes: cuffed tracheostomy tubes have an inflatable balloon around the distal end that seals the trachea, preventing air leak around the tube (important for mechanical ventilation) and reducing aspiration risk. Uncuffed tubes allow air to flow around the tube, which enables the patient to speak (by directing airflow up through the vocal cords) and is used when mechanical ventilation is not needed. The cuff is inflated with air using a syringe — cuff pressure should be maintained at 20-25 cmH2O (checked every 8-12 hours with a cuff manometer). Over-inflation causes tracheal mucosal ischemia and necrosis. Under-inflation allows aspiration and air leak.

Routine tracheostomy care is performed every 8 hours (or more frequently if secretions are copious) and includes inner cannula maintenance, stoma site care, and tie/holder assessment. Inner cannula care: for reusable inner cannulas (metal or certain plastic types), remove the inner cannula, soak it in hydrogen peroxide solution (half-strength — equal parts hydrogen peroxide and normal saline), clean with a small brush or pipe cleaner to remove dried secretions, rinse with normal saline (never put hydrogen peroxide back into the airway), and reinsert. For disposable inner cannulas (the increasingly common standard in most hospitals), simply remove the used cannula, discard it, and insert a new one. Disposable cannulas are faster, reduce infection risk from incomplete cleaning, and are the preferred approach in most acute care settings. The inner cannula must be changed or cleaned on schedule. A mucus plug that occludes the inner cannula creates a life-threatening obstruction — the patient cannot breathe through a plugged tube. This is the most common preventable tracheostomy emergency, and it happens when inner cannula maintenance is delayed or forgotten. A patient who is suddenly working harder to breathe, has increased respiratory rate, or is desaturating — check the inner cannula first. Remove it. If the patient's breathing immediately improves, the inner cannula was the problem. Clean or replace it and reinsert. Stoma site care: clean around the stoma with half-strength hydrogen peroxide on cotton applicators, then rinse with normal saline. Dry the area. Apply a precut tracheostomy dressing (not a cut gauze — cutting gauze leaves loose threads that can be aspirated into the airway) under the faceplate. Assess the stoma for redness, swelling, purulent drainage, granulation tissue, and skin breakdown. Report any signs of infection. Tie changes: tracheostomy ties or Velcro holders keep the tube in the stoma. They should be snug enough that one finger fits between the tie and the neck — too loose and the tube can be coughed out, too tight and the ties cause skin breakdown and restrict venous return. Tie changes require two people: one holds the tube securely in place while the other changes the ties. Never cut the old ties before the new ones are secured — if the tube dislodges during a one-person tie change with no securing hand, you have an accidental decannulation emergency.

Tracheostomy suctioning removes secretions from the trachea and main bronchi that the patient cannot clear independently (because the trach tube prevents effective coughing in most patients, especially those with cuffed tubes). Suctioning is performed as needed based on assessment — audible secretions, increased respiratory effort, decreased SpO2, or visible secretions in the tube — not on a fixed schedule. The suctioning procedure: use a suction catheter that is no larger than half the internal diameter of the tracheostomy tube (a catheter that is too large occludes the airway during suctioning). For an 8mm trach tube, use a 12-14 French catheter. Pre-oxygenate with 100% FiO2 for 30-60 seconds before suctioning (suctioning removes air along with secretions, causing transient hypoxia). Insert the catheter gently without suction applied — advance to the point of resistance (where the catheter reaches the carina or a bronchial wall), then withdraw 1 cm. Apply suction only during withdrawal — intermittent suction while rotating the catheter and withdrawing over no more than 10-15 seconds. The 10-15 second limit is firm: prolonged suctioning causes hypoxia, bradycardia (vagal stimulation from tracheal irritation), and mucosal trauma. Suction pressure: adults 100-150 mmHg. Pediatric 80-100 mmHg. Neonatal 60-80 mmHg. Excessive pressure damages tracheal mucosa and can cause bleeding. Insufficient pressure fails to clear secretions, requiring repeated passes that are more traumatic than a single effective pass. Closed suctioning systems (in-line suction catheters) allow suctioning without disconnecting the ventilator circuit — critical for mechanically ventilated patients to maintain PEEP and oxygenation. The catheter stays in a sterile sleeve connected to the ventilator circuit and is advanced through the trach tube as needed. This is the standard for ventilated patients. Assess after each suction pass: respiratory rate, SpO2, lung sounds, secretion characteristics (color, consistency, amount). Allow the patient to recover for at least 30 seconds between passes if multiple passes are needed. Limit to 3 passes per suctioning episode — if secretions are not adequately cleared in 3 passes, reassess whether the patient needs more aggressive intervention (bronchoscopy, increased humidification, mucolytics). NurseIQ includes suctioning technique scenarios with pressure and duration parameters, catheter sizing exercises, and complication recognition practice.

Tracheostomy emergencies require rapid, protocol-driven responses. These are scenarios where hesitation costs airway — and airway is life. Accidental decannulation (the tube comes out): this is the most feared tracheostomy emergency. Your response depends on whether the tracheostomy is mature (>7 days old, established tract) or fresh (<7 days old, tract not yet formed). For a mature trach: the stoma tract is established and will remain open briefly. Attempt to reinsert the tracheostomy tube — insert the obturator into the outer cannula, lubricate the tip with water-soluble lubricant, gently insert through the stoma using a downward-and-inward angle, remove the obturator immediately after insertion, insert the inner cannula, inflate the cuff, verify placement by auscultating breath sounds and checking for CO2 on capnography, and secure with ties. If the same-size tube will not reinsert, try one size smaller. For a fresh trach (<7 days): DO NOT attempt blind reinsertion. The tract is not mature and the tube may create a false passage into the pretracheal tissue rather than the trachea — this is catastrophic because you are ventilating tissue, not lung. Instead: call for help immediately, cover the stoma with a moist gauze, tilt the head back to open the upper airway, and ventilate via bag-valve-mask over the mouth and nose (the stoma is covered, so air flows through the upper airway as it would for any patient). The surgeon or anesthesiologist will reinsert the tube under direct visualization. Tube obstruction (mucus plug blocking the airway): signs include acute respiratory distress, inability to pass a suction catheter through the tube, and no air movement through the tube despite respiratory effort. Immediate actions: 1. Remove the inner cannula — if the obstruction is in the inner cannula, this instantly restores the airway through the outer cannula. 2. Attempt suctioning through the outer cannula with saline instillation (0.5-1 mL normal saline into the tube to loosen the plug, then suction). 3. If the obstruction cannot be cleared, remove the entire tracheostomy tube and ventilate through the stoma (if mature) or via bag-valve-mask (if fresh). 4. Prepare for emergency reinsertion or intubation. Bedside emergency equipment (must be at the bedside of every tracheostomy patient at all times): obturator for the current tube, a spare tracheostomy tube of the same size, a spare tube one size smaller, a bag-valve-mask (with mask that can seal over the stoma), suction equipment with catheters, and 10 mL syringe for cuff inflation/deflation. Verify this equipment every shift. A missing obturator during an accidental decannulation is a preventable disaster. NurseIQ includes tracheostomy emergency response simulations that test rapid decision-making for decannulation and obstruction scenarios.
