Tracheostomy cuffs why inflate

It is not necessary to deflate the cuff to perform suctioning. After determining amount of air needed to obtain minimum occluding volume, note amount on patient care plan.

The pressure in the tracheostomy tube cuff should be monitored at least every 8 hours if the cuff is inflated continuously. To inflate the cuff with the digital P-V gauge, set slide gauge at "0 cc" mark and then proceed as described in "cuff pressure measuring using digital P-V gauge" 7 above.

Refer to package instructions concerning cuff management for brands of tracheostomy tubes other than the Shiley disposable cannula low pressure cuffed tracheostomy tube. Always test the tracheostomy tube cuff for leakage before inserting the tube. Inflate the cuff with the volume of air indicated in the following table.

Observe for deflation over several minutes or immerse the tube in sterile saline and observe for leakage. However, with a trach tube, air moves in and out of the tube and does not reach the vocal cords. Cuff Deflations: A person can speak with a trach tube by deflating the cuff and placing a speaking valve.

The pulmonologist or nurse practitioner will order cuff deflations when the patient is ready, or they may order partial deflations on patients who are on the ventilator. The following criteria will need to be met before cuff deflations will be considered:.

A speaking valve is a one-way valve that attaches to the end of a trach tube. It is designed to open when the patient takes a breath and close when the patient exhales. When the valve closes, it forces air up into the airway and across the vocal cords, allowing for sound and speech. The patient will breathe in through the trach and exhale out through the nose and mouth. Placement of a speaking valve should initially be done by a respiratory therapist, pulmonary doctor, or nurse practitioner.

Capping a patient who has an inflated cuff can result in DEATH because this would not allow a patient to breathe in, out or both. A tracheostomy cap red cap covers the opening of the trach tube and blocks air from entering the tube. This forces the patient to breathe in and out through their nose and mouth. This is often the last step before the trach is removed decannulation. If the trach can be capped for a long enough time without any problems, it is probably safe to be removed. Patients on ventilators can be allowed to speak by doing partial cuff deflations.

The respiratory therapist will deflate the cuff enough for air to leak past the tube and across the vocal cords but will leave enough air in the cuff to allow for proper ventilation of the patient.

If the cuff were completely deflated, all of the air would escape out of the nose and mouth and would not be delivered to the lungs as a breath. After the stoma is clean, place a gauze pad under the trach tube. Journal of Critical Care, 28 2 , Passy Muir Valves. Educational Products. International Distributors. How to Order.

For one, it directs airflow through the tracheostomy tube in and out of the lungs. Inflation allows the clinician to control and monitor ventilation when the patient is on mechanical ventilation. Secondly, inflation can reduce the amount and speed of aspiration, providing some protection in the patient who may have gross emesis or reflux when aspiration of gastric contents may occur. Aspiration occurs at the level of the vocal cords. A tracheostomy is placed below the vocal cords.

Thus material sitting on top of the cuff is already aspirated. Aspirated and pooled secretions sitting on top of the cuff has the potential to colonize leading to infection. Secretions sitting on top of the cuff also have the potential to harden forming a mucous plug which could easily fall into the lungs.

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.
