Question 2

Correct Answer:

Verified

Changes in compliance may be assessed using the pressure-volume graphical display.By assessing the slope of the loop,changes in compliance may be determined.Be sure to save or print out a pressure volume loop to compare with subsequent loops.A non-graphic method is to determine static compliance measurements but often images are easier to understand.

If the volume wave form does not reach zero on exhalation,the practitioner can determine which of the following?
