performed a systematic review to determine the accuracy of the “cuff-leak” test to predict upper airway edema prior to extubation. The authors concluded that a positive cuff-leak test (i.e., absence of an air-leak) indicates an elevated risk of upper airway obstruction and re-intubation.Click to see full answer. Also to know is, what is a cuff leak test?Prior to extubation, the cuff leak is usually checked. This consists of deflating the cuff of the endotracheal tube to verify that gas is able to move around the tube. Absence of a cuff leak suggests the presence of airway edema, increasing the risks of post-extubation stridor and reintubation.Beside above, how do you perform a leak test on an intubated patient? This easy to perform, noninvasive test involves deflating the balloon cuff on the endotracheal tube (ETT) and observing whether the patient can breathe around it. Detection of air movement auscultation suggests that the airway is patent. A complete absence or reduction in leak would raise the concern of LE. In this regard, how do you assess an endotracheal cuff leak? Inspect the pilot balloon; rule out leaking pilot balloon valve. Evaluate need for chest x-ray to confirm placement. Evaluate need for an airway specialist (someone who can intubate) to check tube placement with laryngoscope. Suction oral airway, deflate cuff, measure amount of air needed to seal.When should you Extubate a patient?Extubation should not be performed until it has been determined that the patient’s medical condition is stable, a weaning trial has been successful, the airway is patent, and any potential difficulties in reintubation have been identified.
