Auto PEEP is measured by (a) expiratory hold (b) both (c) inspiratory hold (d) none.
Understand the Problem
The question is asking us to identify the method of measuring Auto PEEP (Positive End-Expiratory Pressure), which is critical in respiratory physiology. The options provided suggest a choice among different types of holds during the respiratory cycle.
Answer
expiratory hold
The final answer is expiratory hold.
Answer for screen readers
The final answer is expiratory hold.
More Information
Auto-PEEP, also known as intrinsic PEEP, is measured by performing an end-expiratory pause or hold maneuver for 0.5 to 2 seconds, which allows for the measurement of the pressure in the airways at the end of exhalation.
Tips
A common mistake is confusing Auto-PEEP measurement with inspiratory hold maneuvers, which are not used for this purpose.
