Why would you deflate a tracheostomy cuff?
The definition of aspiration is when any food, liquid, or other matter passes below the vocal folds. Therefore, the cuff cannot prevent aspiration as it is located below the vocal folds (see Figure 1). When neither mechanical ventilation or a risk of gross aspiration is present, the cuff should be deflated.
Can trach patients eat with cuff inflated?
If your tracheostomy tube has a cuff, the speech therapist or provider will ensure the cuff is deflated during meal times. This will make it easier to swallow. If you have a speaking valve, you may use it while you eat.
How much air should be in a trach cuff?
How to Inflate Cuff. Measure 5 to 10 mL of air into syringe to inflate cuff. If using a neonatal or pediatric trach, draw 5 ml air into syringe. If using an adult trach, draw 10 mL air into syringe.
What is the difference between cuffed and uncuffed Trach?
Tracheostomy tubes can be cuffed or uncuffed. Uncuffed tubes allow airway clearance but provide no protection from aspiration. Cuffed tracheostomy tubes allow secretion clearance and offer some protection from aspiration, and positive-pressure ventilation can be more effectively applied when the cuff is inflated.
What happen if tracheostomy cuff over inflated?
Excessive tracheal tube cuff pressure can cause mucosal ischaemia leading to tracheal stenosis or tracheooesophageal fistulae [1] and under-inflation of the cuff has been associated with an increased risk of ventilator-associated pneumonia [2].
What is the difference between a cuffed and uncuffed Trach?
What does a cuff on a trach do?
A cuff is necessary when a patient is on a mechanical ventilator. Inflating the cuff during mechanical ventilation makes sure that air is entering the lungs and not escaping through the nose and mouth. The cuff also prevents aspiration of saliva in patients who have trouble swallowing.
Can you talk with a cuffed trach?
If your tracheostomy has a cuff, it will need to be deflated. Your caregiver should make the decision about when to deflate your cuff. When the cuff is deflated and air can pass around your trach, you should try to talk and make sounds. Speaking will be harder than before you had your trach.
When to inflate or deflate the tracheostomy tube cuff?
To inflate or deflate Deflating the cuff is the way to go (Bivona foam trach is the exception). After the first 24 hours post tracheostomy, benefits of cuff deflation can be safe. Some airflow is reestablished through the upper airway when the cuff is deflated.
Are there any misconceptions about the tracheostomy cuff?
Clinicians often have a misconception that the tracheostomy cuff prevents aspiration. However, evidence indicates that: Aspiration occurs at the level of the vocal folds. Therefore, any material that reaches the tracheostomy cuff has already been aspirated.
Where does aspiration occur in the tracheostomy cuff?
Aspiration occurs at the level of the vocal folds. Therefore, any material that reaches the tracheostomy cuff has already been aspirated. The cuff may create a reservoir for aspirated and pooled secretions to colonize.
What are the signs of successful cuff deflation?
Medical stability, respiratory stability and the amount of above the cuff secretions (less than 1ml/hr) were the main indicators for successful cuff deflation (Pryor, L et al, 2016). For information specific for patients with COVID-19 for cuff deflation please see COVID-19 and Tracheostomy and Mechanical Ventilation.

How to monitor the patient during cuff deflation?
Monitor the patient’s vital signs during cuff deflation, particularly when it is the initial time. If vitals are stable, next suction via the mouth and/or stoma as necessary to remove any secretions prior to cuff deflation. If available, above the cuff suctioning can be utilized.
What happens to the airway when the cuff is deflated?
When the cuff is deflated, some airflow is reestablished through the upper airway. There is movement of airflow both through the tracheostomy tube as well as through the upper airway. This increases the effective airway diameter.
