Answer: Assist control mode ventilation

Flashcard 57: _____ delivers oxygen at 40-60 L/min and increases PEEP

Answer: High-flow nasal cannula

Flashcard 58: Laryngeal mask airway is associated with _____ risk of gastrointestinal aspiration when compared with tracheal intubation.

Answer: increased

Flashcard 59: Patients with an RSBI _____ are eligible candidates for successful extubation

Answer: < 105

Extra: RSBI (Rapid Shallow Breathing Index) = Frequency / Tidal Volume (f/Vt in Liters). An RSBI < 105 breaths/min/L is a predictive parameter for successful weaning and extubation.
