A tracheostomy is a surgical opening made in the front of the neck, directly into the windpipe, to create an alternative airway. A short curved tube is placed through this opening (called a stoma) so air bypasses the nose, mouth, and throat entirely. The procedure is one of the most common in intensive care units and can be either temporary or permanent, depending on why it’s needed.
Why a Tracheostomy Is Performed
The most common reason is prolonged mechanical ventilation. When someone needs a breathing machine for more than a week or two, having a tube down the throat (endotracheal intubation) starts causing damage to the vocal cords and airway lining. A tracheostomy is more comfortable, reduces airway resistance, and allows the patient to be more awake and mobile while still receiving ventilator support.
Other reasons include an airway blocked by a tumor, severe swelling, or trauma to the face or neck. People with neurological conditions that weaken the muscles used for breathing or swallowing, such as severe stroke or spinal cord injury, may also need one. In trauma patients expected to need a ventilator for more than seven days, guidelines from the Eastern Association for the Surgery of Trauma recommend considering an early tracheostomy, which can shorten time on the ventilator and reduce the risk of pneumonia.
How the Procedure Works
The tube is placed between the second and third rings of cartilage in the trachea, roughly at the base of the neck. There are two main approaches.
A surgical tracheostomy involves a full dissection of the tissue in front of the windpipe, done in an operating room under direct vision. A percutaneous tracheostomy uses a needle puncture followed by gradual dilation of the opening, and it can be performed at the bedside in the ICU. Both approaches have similar rates of major complications. The bedside technique, however, carries a significantly lower risk of wound infection (roughly 70% lower in pooled analyses) and avoids the risks of transporting a critically ill patient to an operating room.
Patients with difficult neck anatomy, blood clotting disorders, or a history of previous tracheostomy are generally not candidates for the bedside approach and undergo the surgical version instead.
Types of Tracheostomy Tubes
Not all tracheostomy tubes are the same, and the type used depends on the patient’s needs at each stage of recovery.
- Cuffed tubes have a small inflatable balloon near the tip that seals the space between the tube and the tracheal wall. This seal is essential for patients on a ventilator because it prevents air from leaking and helps minimize saliva or fluids from reaching the lungs.
- Uncuffed tubes are used once a patient no longer needs ventilator support. Without the balloon, air can flow around the tube and up through the vocal cords, which is an important step toward speaking again.
- Fenestrated tubes have small holes along the curved portion that allow air to pass upward through the throat. These are used specifically to help patients practice breathing through their natural airway and to prepare for eventual tube removal.
Most tubes also have a removable inner cannula, a smaller tube nested inside the outer one. This inner piece can be pulled out for cleaning without disturbing the main tube, which is important because mucus builds up quickly.
What Daily Care Looks Like
A tracheostomy requires consistent daily maintenance, whether in a hospital or at home. The inner cannula needs cleaning or replacing at least every 12 to 24 hours, and more often if secretions are thick or heavy. The skin around the stoma needs a clean, dry dressing at least once per nursing shift, with immediate changes if the dressing gets wet or soiled.
Suctioning is the other major task. Because the tracheostomy tube bypasses the throat, the body can’t clear mucus the way it normally would through coughing. A thin catheter is inserted through the tube to suction out secretions, but only when there are audible signs of buildup, not on a fixed schedule. Each pass lasts no more than 15 seconds, with at least 30 seconds to a minute between passes to let the patient recover. The catheter should be no wider than half the tube’s inner diameter to avoid blocking airflow during the process. In patients with fenestrated tubes, a standard inner cannula must be inserted before suctioning, or the catheter can poke through the holes and damage the tracheal wall.
Speaking With a Tracheostomy
One of the biggest concerns for patients and families is whether speech is possible. With a standard cuffed tube and the cuff inflated, it isn’t, because no air reaches the vocal cords. But as patients improve, a one-way speaking valve can restore the ability to talk.
The valve attaches to the outer opening of the tube. It opens during inhalation, letting air flow in through the tube as usual. On exhalation, it closes, redirecting air upward around the tube, through the vocal cords, and out through the mouth and nose. This restores the pressure below the vocal cords that’s needed for speech. The cuff must be deflated for the valve to work, since air needs a path around the tube to escape upward. Speaking valves can even be connected to a ventilator circuit for patients who still need breathing support, though the ventilator settings need adjustment to account for the air escaping through the upper airway.
Beyond speech, these valves also improve swallowing function and restore the sense of smell, since air once again flows through the nose.
Possible Complications
Most tracheostomies go smoothly, but complications do occur. In one study of critically ill neurosurgical patients, the most common issues were mucus buildup blocking the tube (about 7% of cases), bleeding from multiple insertion attempts (6%), and excessive bleeding (3%). Less common but more serious problems included the tube being placed alongside rather than inside the trachea (about 1%), tears in the back wall of the windpipe (under 1%), and collapsed lung (under 1%).
Over the longer term, the main concern is narrowing of the airway (tracheal stenosis), which can develop at the stoma site or where the cuff sits against the tracheal wall. Keeping cuff pressure at appropriate levels and downsizing the tube as soon as possible help reduce this risk. Infection at the stoma site is another possibility, which is why keeping the area clean and dry matters so much.
Getting the Tube Removed
Removal of a tracheostomy tube, called decannulation, happens when the original reason for the tracheostomy has resolved and the patient meets several criteria. They need to be alert, have a strong cough to clear secretions on their own, swallow without food or liquid entering the airway, and have adequate lung function for breathing independently.
The process typically involves two steps. First, a flexible camera is passed through the nose to check that the upper airway is open, at least one vocal cord is moving properly, and swallowing is safe. Patients may be given colored liquids to swallow while the camera watches for any leakage into the airway. If that goes well, the tube is capped, forcing the patient to breathe entirely through the nose and mouth while the tube remains in place as a safety net. This capping trial tests whether the patient can handle the resistance of their natural airway and clear secretions on their own. If they tolerate it without drops in oxygen or signs of distress, the tube is removed.
After removal, the stoma typically closes on its own within days to weeks. In some cases, a small surgical closure is needed.
Coordinated Care and Recovery
Recovery with a tracheostomy works best when multiple specialists are involved. Structured interprofessional teams that include respiratory therapists, speech therapists, and nursing staff have been shown to lead to earlier use of speaking valves, faster time to speech, quicker decannulation, and fewer complications overall. Programs like the “Trach Trail” pathway have demonstrated how coordinated care can smooth the transition from ICU to home and reduce setbacks along the way.
For patients going home with a tracheostomy, caregiver education is critical. Family members or home health aides learn suctioning technique, inner cannula cleaning, stoma care, and how to recognize signs of a blocked tube. Home nursing support and the right equipment, from portable suction machines to humidifiers that keep secretions from drying out, make long-term tracheostomy life manageable and safe.
