➡️ Question:
A 63-year-old female patient is receiving pressure-controlled A/C mechanical ventilation. Which of the following changes would occur if her lung compliance were to decrease?
A. Her delivered volume will decrease
B. Her peak pressure will increase
C. Her inspiratory time will increase
D. Her PEEP level will decrease
➡️ Rationale Explanation:
To get this one correct, you must have a basic understanding of lung compliance. You also have to take into account that the ventilator is in the pressure control mode, which means that the pressure is preset. If there is a decrease in lung compliance when the ventilator is operating in the pressure control mode, the machine will continue delivering a constant pressure. But, since the lungs don’t expand as much when there is decreased compliance, it reaches the set pressure limit much faster. That means that there will be a decreased tidal volume. In this case, the inspiratory time will decrease and the PEEP levels should not be affected.
