Question

what assessment is done in a ventilator ?

assess the ventilator for leaks - describe the graphics , types of alarms and how is fixed. Explain potential sites for leaks

Answer 1

Ventilator assessment:

1. Observe and document - Airway type, size and position. Character of insertion site, Date airway inserted, pulmonary assessment of Inspection, palpation, Percussion band Auscultation.

2. Provide oral care. Reapply ETT ( Endotracheal tube) q24h prn ( once a day when necessary).

3. Provide tracheal care and replace inner cannula q12h.

4. Monitor for complications.

5. Suction as needed.

6. Wean and extubate.

​​​​Ventilator leak test: The cuff leak test is proposed as a simple method to predict the occurrence of post extubation stridor. The test is performed by cuff deflation and measuring the expired tidal volume a few breaths later (VT) with and without a deflated cuff.

Large leaks can compromise inspiratory and expiratory pressures band tidal volume delivery. However, the most common asynchrony during Noninvasive ventilation is auto triggering caused by leaks and the inability of the ventilator to distinguish the patient's trigger signal within the noise of the leak.
