who is receiving mechanical ventilation. This value can be obtained by dividing the
patient's tidal volume by which of the following:
A. (Pplat - PEEP)
B. (PIP - PEEP)
C. (PIP - Paw)

An alert 59-year-old male patient is orally intubated with an endotracheal tube. During a
weaning trial, the patient was switched to CPAP mode with an FiO2 of 40%. Within the
first 5 minutes, the patient's respiratory rate has increased from 22 to 31 breaths/min
with increased usage of accessory muscles while breathing. Which of the following
would you recommend?
A. Return the patient to full ventilatory support B. Increase the FiO2 to 50%
C. Apply 5-10 cm H2O of pressure support
D. Extubate the patient and reassess - ANSWER C?
A..
