cuff leak test in COVID-19

Q: Routine cuff leak should be performed in all COVID-19 patients on extubation?

A) True
B) False

Answer: B

Cuff leak test may have a potential of aerosolization. It should be avoided routinely in COVID-19 patients unless clinically indicated. It can be done judiciously in patients with suspicion of upper airway edema, prolonged intubation of more than a week, age more than 80 years, large endotracheal tube (ETT), and known trauma during intubation. In an ideal situation, if a clinician feels an extreme necessity of doing a cuff leak test prior to extubation, it should be performed in an airborne isolation room. A successful cuff leak test consists of volumes of greater than 110 mL or greater than 24 percent of the delivered tidal volume (TV).
