Question

A 60 kg (132 lb) patient is being mechanically ventilated with the following settings: VC, A/C; VT 500 mL, respiratory rate 12/min, FIO₂ 1.00 and 10 cm H₂O PEEP. The patient's peak airway pressure is 60 cm H₂O and his SpO₂ is 85%. A current chest x-ray shows diffuse bilateral infiltrates. Which of the following is the most appropriate action in order to reduce peak airway pressure?

A. Increase the frequency.
B. Change to airway pressure release ventilation.
C. Decrease the inspiratory time.
D. Increase PEEP to 15 cm H₂O

Answer 1

The most appropriate action to take in order to reduce peak airway pressure in this patient is to change to airway pressure release ventilation (APRV).

Step-by-step explanation:

The most appropriate action to take in order to reduce peak airway pressure in this patient is to B. Change to airway pressure release ventilation. Airway pressure release ventilation (APRV) is a mode of mechanical ventilation that allows for spontaneous breathing while maintaining adequate lung recruitment and ventilation. By switching to APRV, the patient can have better control over their breathing, allowing for a reduction in peak airway pressure.
