Trach care is the daily routine of keeping a tracheostomy tube clean, open, and functioning so a person can breathe safely. It involves suctioning mucus from the airway, cleaning the inner cannula of the tube, caring for the skin around the opening (called a stoma), and changing the dressing that sits beneath the tube’s faceplate. Whether performed in a hospital or at home, trach care follows the same core steps, though the technique and supplies differ slightly between the two settings.
Why a Tracheostomy Needs Ongoing Care
A tracheostomy is a surgically created hole through the front of the neck into the windpipe. A tube sits in that hole to keep it open, and a strap around the neck holds it in place. The tube bypasses the nose and mouth entirely, which means the body loses its natural system for filtering, warming, and moisturizing incoming air. Cold, dry air entering the windpipe directly causes mucus to thicken and build up faster than it normally would. Without regular clearing, that mucus can partially or fully block the tube and make breathing difficult.
The stoma itself is also a wound that never fully closes as long as the tube is in place. Moisture, friction from the tube, and contact with secretions all create opportunities for skin irritation and infection. Trach care addresses both problems: keeping the airway clear and keeping the surrounding skin healthy.
Suctioning the Airway
Suctioning is the most time-sensitive part of trach care. A thin, flexible catheter is connected to a portable suction machine and inserted through the tracheostomy tube to pull out mucus the person can’t cough up on their own. You suction only when there are signs it’s needed, such as visible mucus in the tube, noisy or gurgling breathing, or the person signaling difficulty breathing. Routine suctioning on a set schedule isn’t recommended because the catheter itself can irritate the airway lining.
Each pass of the catheter should last no more than 15 seconds. The catheter is inserted without suction applied, then suction is turned on as you slowly withdraw it. Between passes, the person needs 30 to 60 seconds to recover, and no more than two passes should be done in a single session. Suction pressure matters too. For adults, the machine should be set to no more than 150 mmHg. For children the ceiling is 120 mmHg, for infants 100 mmHg, and for newborns 80 mmHg. Too much pressure can damage the delicate tissue lining the airway.
There are two approaches to insertion depth. Shallow suctioning means inserting the catheter only to the length of the tracheostomy tube itself. Deep suctioning means advancing the catheter until you feel resistance, then pulling back about one centimeter before applying suction. Your care team will specify which method to use based on the person’s situation.
Cleaning the Inner Cannula
Many tracheostomy tubes have two parts: an outer cannula that stays in the stoma and a removable inner cannula that slides inside it. The inner cannula catches mucus buildup and can be pulled out for cleaning or replacement without disturbing the outer tube. This design makes daily maintenance much simpler.
Inner cannulas come in two types. Disposable ones are used for up to 24 hours and then thrown away. In hospital settings, they’re often swapped out twice a day. Reusable ones, found in brands like Bivona and Portex, can be cleaned and reinserted. Pediatric reusable tubes can typically be cleaned and reused up to five times, while adult versions last up to ten uses. To clean a reusable cannula, you soak it in distilled water with a small amount of mild, fragrance-free dish soap, then use a pipe cleaner or soft-bristled brush to clear any mucus from inside the tube. Vinegar and hydrogen peroxide should not be used for soaking the cannula itself.
At a minimum, the inner cannula should be inspected twice daily and cleaned every 12 to 24 hours. If mucus is accumulating quickly, it may need attention more often.
Stoma and Skin Care
The skin around the stoma takes a beating. It’s constantly exposed to moisture from secretions, pressure from the tube and faceplate, and friction from the securing ties. A clean, dry dressing (called a split gauze) sits between the faceplate and the skin to absorb moisture and reduce irritation. This dressing should be changed at least once per nursing shift in the hospital, or at least once daily at home, and immediately if it becomes wet or soiled.
Each time the dressing is changed, the stoma area should be gently cleaned. Moderately warm tap water or a mild cleanser works well. Cotton-tipped swabs help reach the skin directly around the tube. After cleaning, the skin should be dried thoroughly before a new dressing is applied. Some care teams recommend applying a barrier film to the surrounding skin to protect it from enzymes and moisture in secretions.
Signs of skin trouble include redness, raw or eroded patches, oozing fluid, and sensations of itching or burning around the stoma. Catching these early is important because peristomal skin breakdown can progress quickly from mild redness to partial-thickness skin loss if the cause isn’t addressed.
Humidification
Because the tracheostomy tube bypasses the nose and mouth, the body’s natural humidification system is out of the picture. The nose normally warms incoming air to body temperature and saturates it with moisture before it reaches the lungs. Without that conditioning, secretions dry out and form crusts that can narrow or plug the tube.
A heat and moisture exchanger, sometimes called an artificial nose, is a small device that attaches to the opening of the trach tube. It captures warmth and moisture from exhaled air and returns it to the next breath. These devices are lightweight, inexpensive, and don’t require any power source. For people on a ventilator, more advanced versions add supplemental moisture by heating a small reservoir of purified water to its evaporation point and introducing it into the airflow. At home, some people also use a room humidifier or saline nebulizer treatments to keep secretions thin and manageable.
Hospital vs. Home Technique
In the hospital, trach care is performed using sterile technique. That means sterile gloves, brand-new trach tubes, and single-use supplies. Hospitals have higher concentrations of resistant bacteria, so the extra precaution is warranted.
At home, the standard shifts to clean technique. Hand washing is still essential, but gloves are optional. Tracheostomy tubes that have been properly cleaned can be reused, and trach ties don’t need to be replaced unless they’re soiled or wet. The home environment has fewer circulating pathogens, which makes this simplified approach both safe and practical. Families are trained on clean technique before discharge and given specific instructions tailored to their tube type and supplies.
Essential Supplies to Keep on Hand
A well-stocked home trach care station prevents scrambling during urgent moments. The core supplies include:
- Trach tubes: the correct size plus a backup one size smaller in case the primary tube can’t be reinserted
- Suctioning equipment: a portable suction machine, suction catheters in the prescribed size, replacement tubing, canisters with lids, and respiratory saline in small vials
- Cleaning supplies: pipe cleaners or soft-bristled brushes, mild fragrance-free dish soap, distilled water, cotton-tipped swabs, and hydrogen peroxide for skin cleaning
- Dressings and securing devices: split gauze pads, Velcro trach ties or twill tape, and scissors
- Emergency gear: a manual resuscitation bag with an appropriately sized mask, water-based lubricant for reinsertion, and a 60 cc syringe for cuff management
A few of these items, including hydrogen peroxide, cotton swabs, water-based lubricant, and nonsterile gloves, are typically not covered by insurance and need to be purchased separately.
Speaking With a Trach Tube
A tracheostomy diverts air away from the vocal cords, which makes speaking difficult or impossible with a standard setup. A one-way speaking valve solves this by allowing air in through the trach tube on inhalation but closing on exhalation, redirecting air upward through the vocal cords and out the mouth and nose. This restores the ability to produce voice.
Not everyone is a candidate for a speaking valve right away. The person needs to be medically stable, able to tolerate having the tube’s cuff deflated (so air can flow around the tube), and able to manage their secretions through coughing or swallowing. The airway above the tube must also be open enough to allow air to pass through freely on exhalation. A physician’s order and a bedside assessment are required before the first trial, and valve use can often begin within 72 hours of admission if these criteria are met.
What to Do if the Tube Comes Out
Accidental decannulation, where the tube is coughed out, pulled out, or dislodged, is the most serious trach-related emergency. How you respond depends on how established the tracheostomy is. A fresh tracheostomy (typically less than seven days old) has a tract that hasn’t fully formed yet and can close or create a false passage if reinsertion is attempted without training. In this situation, the safest approach is to call emergency services and attempt to maintain breathing through the mouth and nose if possible.
For a well-established tracheostomy, caregivers trained in reinsertion can replace the tube using a backup tube (the same size or one size smaller) with the obturator in place and lubricated. Having a backup tube, lubricant, and ties at the bedside at all times is not optional. It’s the single most important safety measure for anyone living with a tracheostomy at home.
