Tracheostomy Button: Clinical Uses, Benefits, and Risks

A tracheostomy button is a specialized airway device used to maintain a tracheostomy stoma after a tracheostomy tube has been removed. It is most useful for patients who no longer need a standard tracheostomy tube for continuous airway support but still need the stoma kept open for safety, secretion clearance, or future airway access.

In respiratory care, the tracheostomy button is important because it allows a patient to breathe, speak, cough, and eat more normally while preserving access to the trachea if respiratory support becomes necessary again.

What Is a Tracheostomy Button?

A tracheostomy button, sometimes called a trach button, is a short, hard plastic tube placed into a tracheostomy stoma. Its main purpose is to keep the opening from closing after a tracheostomy tube has been removed.

Unlike a standard tracheostomy tube, a tracheostomy button is not typically used as the primary airway for long-term mechanical ventilation. Instead, it acts as a stoma-maintaining device. It helps preserve the opening so that a tracheostomy tube can be reinserted quickly if the patient develops respiratory distress or needs a secure airway again.

This makes the tracheostomy button a useful device during the transition between having a full tracheostomy tube and allowing the stoma to close completely. In some patients, the button may be temporary. In others, it may be used for a longer period because the patient remains at risk for airway problems or may need repeated tracheostomy access.

For respiratory therapy students, the key point is that a tracheostomy button is not the same as a cuffed tracheostomy tube. It does not provide the same level of airway protection or ventilatory support. Its main role is to maintain the stoma while allowing more normal upper-airway function.

Purpose of a Tracheostomy Button

The primary purpose of a tracheostomy button is to maintain the tracheostomy stoma. After a tracheostomy tube is removed, the opening can begin to close. In many cases, closure is desired because the patient no longer needs artificial airway access. However, some patients are not ready for the stoma to close completely.

A physician may decide that the patient no longer needs a traditional tracheostomy tube but still needs access to the trachea preserved. This can happen when a patient is recovering from a respiratory condition, neuromuscular weakness, upper-airway problem, or another disorder that could worsen again.

By keeping the stoma open, the tracheostomy button provides a safety route. If the patient develops respiratory difficulty, a standard tracheostomy tube can be inserted through the existing opening without performing another tracheotomy.

The button can also provide direct access for suctioning. This is helpful when the patient still has difficulty clearing secretions. In some patients, secretion clearance may remain a major issue even after they no longer require a standard tracheostomy tube.

Another purpose is to allow more normal breathing through the upper airway. When the button is plugged, the patient breathes through the nose, mouth, pharynx, larynx, and trachea. This allows the patient to resume more natural breathing patterns while still keeping the stoma available.

When a Tracheostomy Button Is Used

A tracheostomy button may be used after decannulation when the stoma needs to remain open. Decannulation refers to the removal of a tracheostomy tube. In many patients, the stoma is allowed to close after the tube is removed. However, selected patients may benefit from having the stoma maintained.

A tracheostomy button may be considered for patients who are breathing adequately through the upper airway but still have a risk of respiratory difficulty. It may also be used in patients who may need repeated tracheostomies, such as those with certain neuromuscular diseases or spinal cord injuries.

Examples include patients with myasthenia gravis, quadriplegia, or high cervical spine injury. These patients may have periods when they can breathe without a standard tracheostomy tube, but they may still be at risk for respiratory weakness, secretion retention, or sudden airway compromise.

A tracheostomy button may also be useful in patients with upper-airway problems, obstructive sleep apnea, excessive secretions, or airway pathology such as scarring or tumor. In these cases, the goal is often to maintain airway access without requiring a full artificial airway for continuous ventilation.

The device may also be used in certain laryngectomy patients. After a laryngectomy, the patient breathes through a permanent stoma because the larynx has been surgically removed. Some laryngectomy patients may use button-type devices to help maintain the stoma and prevent narrowing over time.

How a Tracheostomy Button Is Different From a Tracheostomy Tube

A tracheostomy tube is usually longer and is designed to function as an artificial airway. It may be cuffed or uncuffed, fenestrated or nonfenestrated, and may be used for mechanical ventilation, airway protection, suctioning, or bypassing an upper-airway obstruction.

A tracheostomy button is shorter and is mainly designed to keep the stoma open. It does not usually provide the same secure airway as a standard tracheostomy tube. It may allow suctioning, oxygen delivery, aerosol therapy, or temporary connection to respiratory equipment, but it is not ideal for controlled mechanical ventilation.

This distinction matters clinically. If a patient needs reliable positive-pressure ventilation, a cuffed tracheostomy tube is usually more appropriate. A tracheostomy button may allow connection to equipment through a standard adapter, but leakage can occur. Therefore, it should not be viewed as the best option for patients who need dependable ventilatory support.

A tracheostomy button is also more compatible with normal function. Many patients can speak, eat, cough, and breathe through the upper airway more naturally. This is one of its major advantages over a standard tracheostomy tube.

Structure of a Tracheostomy Button

A tracheostomy button has several design features that help it stay in place and function properly. It usually consists of a hollow outer cannula that sits within the tracheostomy stoma.

The proximal end is slightly flared. This flared end helps prevent the button from slipping inward through the stoma. This is important because migration into the airway could create serious problems.

The distal end may be flanged or split into flexible grippers. These help secure the device at the tracheal end and reduce the chance that it will fall out or be pulled out accidentally.

The button may also include a plug, a hollow inner cannula, spacers, or a one-way valve depending on the patient’s needs. Each component changes how the device functions.

A closure plug can be inserted into the outer cannula to seal the opening. When the plug is in place, the patient must breathe through the upper airway. This is often used when the goal is to allow normal breathing while simply keeping the stoma open.

A hollow inner cannula may be used instead of the plug. This allows suctioning and may permit attachment of respiratory care equipment. Some inner cannulas have a standard 15-mm outside diameter adapter, which allows connection to devices such as a T-piece, aerosol setup, or other respiratory therapy equipment.

Role of Spacers

Spacers are an important part of tracheostomy button placement. They help adjust the depth of the button so that it sits correctly in the stoma and trachea.

After the tracheostomy tube is removed, the depth of the stoma may be measured. Spacers of different lengths can then be added to match the patient’s anatomy. The goal is for the device to enter the trachea enough to maintain access without protruding too far into the airway.

This is a major safety issue. If the button is too shallow, it may not maintain useful access to the trachea. It may become unstable or ineffective. If it is too deep, it may irritate the airway, increase resistance, obstruct airflow, or cause respiratory distress.

For exam purposes, an important point is that respiratory distress with an unplugged tracheostomy button may indicate that the button protrudes too far into the trachea. The correction may involve repositioning the device by changing the number or width of the spacers.

Note: Proper placement should allow the patient to breathe without added resistance. If breathing becomes difficult after placement, malposition should be suspected.

Closure Plug and Upper-Airway Breathing

A tracheostomy button may be plugged when the goal is to make the patient breathe through the natural upper airway. With the plug in place, air does not pass through the tracheostomy opening. Instead, the patient inhales and exhales through the nose or mouth.

This helps assess whether the patient can tolerate normal upper-airway breathing. It also allows more natural humidification, filtration, warming of inspired gas, speech, coughing, and swallowing.

The ability to cough through the upper airway is especially important. Coughing helps clear secretions and protect the airway. If the patient can cough effectively with the button plugged, this may suggest improved airway control and secretion clearance.

However, the patient must be carefully monitored. If the patient develops distress while the button is plugged, the plug may need to be removed. The clinician must determine whether the issue is upper-airway obstruction, poor secretion clearance, weak respiratory effort, or another problem.

Hollow Inner Cannula and Suctioning

A hollow inner cannula allows direct access through the tracheostomy button. This can be useful when the patient needs suctioning or connection to respiratory therapy equipment.

One of the major advantages of a tracheostomy button is that it allows the stoma to remain available for secretion removal. Some patients can breathe through the upper airway but still have difficulty clearing secretions. In these cases, the button gives the respiratory therapist a route for suctioning without requiring a full tracheostomy tube.

Patency is critical. A suction catheter should be able to pass through the hollow opening. If the catheter cannot pass, obstruction, secretion buildup, blood, foreign material, or malposition should be suspected.

This is a common exam point. If a patient with a tracheostomy button develops difficulty breathing, one of the first concerns is whether the button is patent. Passing a suction catheter through the device helps determine whether the airway opening is clear.

Note: If the button is obstructed and the patient is in distress, the clinician should act quickly. The button may need to be removed and replaced with another button or a standard tracheostomy tube.

One-Way Valve and Speech

Some tracheostomy buttons can be used with a one-way valve. A one-way valve allows gas to move in one direction. With this setup, the patient may inhale through the button but exhale through the upper airway.

This has an important benefit: speech. When exhaled air is redirected through the larynx and vocal cords, the patient can speak. This can improve communication, comfort, and quality of life.

The Kistner tracheostomy button is an example of a button that may include a one-way valve. It has a hollow plastic cannula that keeps the stoma open. The distal end is flanged to help reduce accidental removal. The proximal end is capped with a one-way valve.

During inspiration, the patient can inhale room air or an oxygen- or aerosol-enriched gas source through the button. During exhalation, the valve directs air through the upper airway, allowing speech, eating, and coughing to occur more normally.

Note: This setup may be useful for patients who should not inhale through the upper airway but can exhale through it. Examples include selected patients with neuromuscular disease or high cervical spine injury.

Dead Space and Low Tidal Volume

A tracheostomy button with a one-way valve may provide a physiologic advantage in patients with very small tidal volumes. This is especially relevant in patients with neuromuscular weakness or high spinal cord injury.

In a normal breath, some of the inhaled air remains in the anatomic dead space. This includes the nose, mouth, pharynx, larynx, trachea, and conducting airways. This air does not participate in gas exchange.

For patients with low tidal volumes, dead space can represent a large portion of each breath. This reduces the amount of fresh gas reaching the alveoli. As a result, alveolar ventilation may be reduced, and carbon dioxide removal may become less effective.

When a patient inhales through a tracheostomy button, some upper-airway dead space is bypassed. This can improve the relationship between dead space and tidal volume. The patient may still exhale through the upper airway, which allows speech.

Note: This is one reason a tracheostomy button may be helpful in selected patients with small tidal volumes. It may improve ventilation while preserving communication.

Speaking Valves and Safety

Speaking valves, such as Passy-Muir and Mallinckrodt valves, function in a similar way to other one-way valves. They open during inspiration and close during expiration. When the valve closes during exhalation, gas is redirected through the upper airway and vocal cords, allowing speech.

Speaking valves can be used with tracheostomy tubes or tracheostomy buttons that have the correct standard connection. However, safety is essential.

The patient must be able to exhale. If exhaled gas cannot escape, a dangerous obstruction can occur. This can cause severe respiratory distress and may become life-threatening.

If a speaking valve is placed on a standard tracheostomy tube, the cuff must be deflated. If the cuff is inflated, air cannot pass around the tube and out through the upper airway. This traps exhaled gas.

If a speaking valve is used with a fenestrated tracheostomy tube, special precautions apply. The cuff may remain inflated only if the inner cannula is removed and gas can pass through the fenestration and upper airway. If the setup blocks exhalation, the patient is at serious risk.

Note: With a tracheostomy button, the clinician must also make sure the valve is working correctly and that the patient can exhale through the upper airway. If the patient develops dyspnea after a speaking valve is attached, the valve should be removed and the patient reassessed.

Troubleshooting a Tracheostomy Button

Troubleshooting is a major part of tracheostomy button management. The respiratory therapist must be able to recognize problems quickly and respond appropriately.

Common problems include obstruction, malposition, incorrect spacer size, secretion buildup, blood, foreign material, or valve malfunction. Any of these can cause increased work of breathing or respiratory distress.

One practical way to assess patency is to pass a suction catheter through the button. If the catheter passes easily, the lumen is likely open. If the catheter does not pass, obstruction or malposition should be suspected.

If the patient has a speaking valve attached and reports difficulty breathing, the valve should be removed first. The clinician should then reassess the patient. If breathing improves after removing the valve, the valve may have been defective, obstructed, or inappropriate for that patient at that time.

If the patient continues to have difficulty breathing after the valve is removed, the button itself should be evaluated. It may need to be removed. A new button or a traditional tracheostomy tube may be inserted if airway access is needed.

Note: If distress occurs while the button is unplugged, excessive protrusion into the trachea may be the problem. In that case, the device may need to be repositioned using different spacers.

Placement Confirmation

Proper placement is essential for safe use of a tracheostomy button. The device must sit at the correct depth and should not obstruct the trachea.

In some cases, fiber-optic bronchoscopy may be used to confirm proper placement. This allows direct visualization of the airway and the position of the device. Bronchoscopy may be especially helpful when there are signs of malposition, obstruction, or unexplained respiratory distress.

A correctly positioned tracheostomy button should maintain the stoma without increasing airway resistance. The patient should be able to breathe comfortably according to the intended setup, whether the button is plugged, unplugged, or used with a valve.

The clinician should also make sure that all parts fit together properly. The plug, inner cannula, valve, and connectors should be secure but easy to remove when needed. Equipment that cannot be disconnected quickly may create problems during an emergency.

Tracheostomy Button in Laryngectomy Patients

A tracheostomy button may also be discussed in relation to laryngectomy care. A laryngectomy is the surgical removal of the larynx. After this procedure, the trachea is brought to the skin surface to create a permanent stoma.

This is different from a standard tracheostomy. In a laryngectomy patient, there is no connection between the upper airway and the lungs. The patient cannot breathe through the mouth or nose. All breathing occurs through the stoma.

Because of this, airway management must occur through the stoma or airway device. This includes ventilation, oxygen delivery, aerosol therapy, suctioning, and emergency airway access.

Some laryngectomy patients use laryngectomy tubes or buttons to help maintain the stoma. Over time, some patients may develop stomal stenosis, which means narrowing of the opening. Button-type devices can help prevent or manage this problem by keeping the stoma open.

Note: In these patients, a button may be more than a convenience device. It may be the main route for airway care.

Advantages of a Tracheostomy Button

A tracheostomy button has several advantages for selected patients. The most important advantage is that it keeps the stoma open without requiring a full tracheostomy tube.

This allows the patient to function more normally. Depending on the setup, the patient may be able to breathe through the upper airway, speak, eat, cough, and clear secretions more naturally.

The button also preserves access to the trachea. If the patient develops respiratory distress, a traditional tracheostomy tube can be inserted through the existing stoma. This can avoid the need for another surgical tracheotomy.

The button can also allow direct suctioning of secretions. This is helpful in patients who are improving but still need occasional airway clearance support.

Another advantage is that it may help selected patients with low tidal volumes by reducing upper-airway dead space during inspiration when used with a one-way valve. This can improve ventilation while still allowing exhalation through the upper airway for speech.

Note: Overall, the tracheostomy button provides a balance between safety and normal function.

Limitations and Risks

A tracheostomy button is not appropriate for every patient. It should not be used as a substitute for a secure airway when a patient needs reliable mechanical ventilation or airway protection.

One limitation is that leakage can occur if positive-pressure ventilation is attempted through the button. This makes it less suitable for controlled ventilation compared with a cuffed tracheostomy tube.

Another risk is obstruction. Secretions, blood, mucus plugs, or foreign material can block the button. If the button becomes obstructed, the patient may develop respiratory distress.

Malposition is another concern. If the button protrudes too far into the trachea, it may increase resistance or obstruct airflow. If it does not extend far enough, it may fail to maintain access properly.

Valve misuse can also be dangerous. Any speaking valve or one-way valve must allow the patient to exhale. If exhalation is blocked, severe distress can occur.

Note: For these reasons, patients with tracheostomy buttons require careful assessment, proper device selection, correct placement, and ongoing monitoring.

Respiratory Therapist Responsibilities

The respiratory therapist plays an important role in the care of patients with tracheostomy buttons. The therapist must understand the purpose of the device, how it is assembled, and how to troubleshoot complications.

One responsibility is to assess patency. This may include passing a suction catheter through the button when appropriate. If the catheter cannot pass, the therapist should suspect obstruction or malposition.

Another responsibility is to monitor the patient’s breathing pattern, work of breathing, oxygenation, secretion clearance, and ability to tolerate the device. Any increase in distress should be taken seriously.

The respiratory therapist must also understand how plugs and valves affect airflow. A plugged button forces the patient to breathe through the upper airway. A one-way valve may allow inspiration through the button and expiration through the upper airway. These setups are useful only if the patient can tolerate them.

The respiratory therapist should also be prepared for emergency airway management. If the patient cannot breathe adequately and the button is the source of the problem, it may need to be removed. A standard tracheostomy tube may need to be inserted to reestablish the airway.

Key Takeaways

For respiratory therapy exams, the tracheostomy button is most often tested as a specialized airway device used after decannulation. It keeps the stoma open while allowing the patient to function more normally.

Remember that a tracheostomy button is not primarily used for full ventilatory support. If a patient needs reliable mechanical ventilation, a cuffed tracheostomy tube is usually the better choice.

A suction catheter should be able to pass through the button. If it cannot pass, think obstruction or malposition.

If a patient has dyspnea with a speaking valve attached, remove the speaking valve first and reassess. If the patient improves, the valve may have caused the problem. If distress continues, assess the button and be prepared to remove it.

If distress occurs while the button is unplugged, think excessive protrusion into the trachea. The device may need to be repositioned by changing spacers.

Note: If placement is uncertain, fiber-optic bronchoscopy may be used to confirm position.

Obstruction of the trachea can increase work of breathing and cause respiratory distress.

80. What is the relationship between a tracheostomy button and airway resistance?
A properly placed tracheostomy button should not add significant resistance to breathing.

81. What is the best device for a patient who needs mechanical ventilation at night but wants to communicate during the day?
A fenestrated tracheostomy tube is typically recommended rather than switching between a tracheostomy tube and a tracheostomy button.

82. Why is switching back and forth between a tracheostomy tube and a tracheostomy button not recommended?
Repeatedly changing between the devices is impractical and may damage tracheal tissue.

83. How can a fenestrated tracheostomy tube help a patient who needs nighttime ventilation but daytime speech?
It allows mechanical ventilation when needed and can also permit airflow through the upper airway for speech during spontaneous breathing.

84. Why is a tracheostomy button not the best choice for routine nighttime mechanical ventilation?
It is not ideal for reliable mechanical ventilation because leakage may occur and it does not provide the same secure airway as a cuffed tracheostomy tube.

85. What does it mean when a tracheostomy button is described as a stoma-maintenance device?
It means the device is used primarily to keep the tracheostomy opening patent rather than to provide full ventilatory support.

86. How can a tracheostomy button support supplemental oxygen delivery?
A hollow cannula or adapter may allow oxygen or aerosol-enriched gas to be delivered through the button when needed.

87. How can a tracheostomy button support humidification?
Respiratory therapy equipment may be attached to the button to provide humidified gas when appropriate.

88. What type of airway problem may lead to the use of an uncuffed tracheostomy tube or tracheostomy button?
Upper-airway obstruction, airway pathology, excessive secretions, or the need to maintain airway access without artificial ventilation may lead to their use.

89. Why might a patient with obstructive sleep apnea need a tracheostomy button?
A tracheostomy button may help maintain a patent airway or preserve tracheal access in selected patients with airway obstruction.

90. Why might a patient with upper-airway scarring need a tracheostomy button?
Upper-airway scarring may create airway narrowing, making preserved tracheal access useful for safety and airway management.

91. What is stomal stenosis?
Stomal stenosis is narrowing of the stoma over time.

92. How can button-type devices help laryngectomy patients?
They can help maintain the stoma and reduce the risk of stomal narrowing.

93. How is a laryngectomy patient different from a standard tracheostomy patient?
A laryngectomy patient has no connection between the upper airway and the lungs, so all breathing occurs through the stoma.

94. Why must oxygenation and ventilation in a laryngectomy patient occur through the stoma?
Because the larynx has been removed and the upper airway is no longer connected to the trachea and lungs.

95. What airway procedures must be performed through the stoma in a laryngectomy patient?
Ventilation, oxygen delivery, suctioning, aerosol therapy, and intubation must be performed through the stoma.

96. Why is a tracheostomy button sometimes considered less invasive than a standard tracheostomy tube?
It is shorter and mainly maintains the stoma while allowing more normal upper-airway function when appropriate.

97. What is one advantage of a plugged tracheostomy button during patient assessment?
It helps determine whether the patient can breathe and cough effectively through the upper airway.

98. What should the respiratory therapist monitor in a patient with a tracheostomy button?
The therapist should monitor breathing effort, oxygenation, secretion clearance, airway patency, device position, and tolerance of plugs or valves.

99. What is the most important priority when managing a patient with a tracheostomy button?
The most important priority is maintaining a patent airway and responding quickly to signs of obstruction, malposition, or respiratory distress.

100. What should students remember most about tracheostomy buttons for board exams?
Students should remember that tracheostomy buttons maintain the stoma, allow suctioning and emergency access, support more normal speech and coughing, and are not the preferred device for routine mechanical ventilation.

Final Thoughts

A tracheostomy button is an airway-management device used to maintain a tracheostomy stoma after the tracheostomy tube has been removed. It allows selected patients to breathe, speak, eat, and cough more normally while preserving access to the trachea if airway support is needed again.

The main clinical priorities are correct placement, proper spacer selection, valve safety, and continued patency. Respiratory therapists must recognize signs of obstruction or malposition and respond quickly.

For exam preparation, remember that a tracheostomy button maintains the stoma, allows suctioning and emergency access, and is not the preferred device for routine mechanical ventilation.
