Question

In what scenario is pressure-controlled ventilation (PCV) most often used?

A) when limiting plateau pressure is needed

B) when a pneumothorax is present

C) when the patient has chronic obstructive pulmonary disease

D) when bilateral pneumonia is present

Answer 1

Pressure-controlled ventilation (PCV) is most often used when limiting plateau pressure is needed, such as in acute respiratory distress syndrome (ARDS).

Step-by-step explanation:

Pressure-controlled ventilation (PCV) is most often used in scenarios where limiting plateau pressure is needed, such as in acute respiratory distress syndrome (ARDS). In ARDS, the lungs become stiff and the patients require high-pressure settings to adequately ventilate the alveoli. PCV helps to prevent further lung injury by delivering a controlled and limited amount of pressure to the lungs.
