A tracheostomy is a secured, long-term airway — which is exactly why complacency around it is dangerous. The same tube that makes weaning and mobility easier can, if it clots off or falls out, become a lost airway in minutes. Good trach care is mostly about preventing that.
A standard trach tube has an outer cannula (stays in the airway, held by the neck flange and ties), an inner cannula (removable — this is what you clean or replace to clear secretions without disturbing the airway), and an obturator (a smooth-tipped guide used only during insertion, then taped to the wall above the bed so it's never lost). Tubes may be cuffed (a balloon that seals the airway for positive-pressure ventilation and aspiration protection) or uncuffed, and fenestrated (a hole in the outer cannula that, with the right inner cannula and a cap, allows speech). Know which tube your patient has and its size — it drives everything else.
Because the inner cannula catches secretions, a patient in respiratory distress with a trach should prompt you to remove and inspect/clean or replace the inner cannula early — it's fast, it doesn't disturb the airway itself, and a mucus-plugged inner cannula is a common, quickly reversible cause of distress. Disposable inner cannulas are swapped; reusable ones are cleaned per policy. Adequate humidification (a trach collar with humidified air/oxygen) prevents the drying and crusting that cause plugs in the first place — the trach bypasses the nose's natural humidifier, so you have to replace it.
When the tube is cuffed, cuff pressure matters. Too low and you lose the seal (air leak, aspiration risk, inadequate ventilation); too high and the cuff presses on the tracheal mucosa hard enough to cut off capillary blood flow, causing ischemia, and over time stenosis or a tracheo-esophageal fistula.
| Cuff pressure | Effect |
|---|---|
| Below ~20 cmH2O | Under-inflated: air leak, aspiration of secretions past the cuff, under-ventilation |
| ~20–30 cmH2O (target) | Seals the airway while preserving tracheal mucosal perfusion |
| Above ~30 cmH2O | Over-inflated: mucosal ischemia → necrosis, stenosis, fistula over time |
Measure with a manometer per policy (commonly each shift), not by "feel." Minimal-leak and minimal-occlusive-volume techniques exist, but a manometer-verified pressure in the safe window is the standard.
Suction the trach when the patient needs it — coarse secretions you can hear, a rising work of breathing, visible mucus, desaturation — not on a fixed schedule. Suctioning is uncomfortable and not risk-free.
Assess the stoma for redness, drainage, odor, bleeding, and skin breakdown. Clean around the site with the solution and technique your facility specifies, use a pre-cut trach dressing (never cut gauze — loose fibers can be aspirated), and change ties/velcro holders when soiled. When changing ties, a second person holds the tube in place so it cannot dislodge while the old ties are off — this is a two-person task on a fresh trach. Ties should be snug enough to prevent tube movement but loose enough to slide a finger underneath.
Every trach patient has, at the bedside, at all times: a spare trach tube of the same size and one size smaller, the obturator, a 10 mL syringe for the cuff, functioning suction and catheters, and a bag-valve device. If these aren't there when you take report, get them before you do anything else — the one time you need them, you need them in seconds.
Tracheostomy care rewards routine and punishes complacency. Keep it patent with inner-cannula care, humidification, and as-needed suctioning; keep the cuff between 20 and 30 cmH2O; secure and inspect the site; and above all, know whether the stoma is fresh or mature and have the emergency response — and the bedside kit — ready before the tube ever gives you trouble.
