The two waveforms that are common for pressure scalars are which of the following?
 
  a. Sinusoidal and ascending ramp
  b. Rectangular and exponential rise
  c. Descending ramp and ascending ramp
  d. Exponential decay and descending ramp

Question 2

To help prevent inflated alveoli from collapsing and reexpanding with each breath, the positive end-expiratory pressure (PEEP) level should be set at which point on the deflation part of the loop?
 
  a. Above the upper inflection point
  b. Below the upper inflection point
  c. Above the lower inflection point
  d. Below the lower inflection point

Answer to Question 1

ANS: B
Pressure waveforms are usually the rectangular or rising exponential type.

Answer to Question 2

ANS: C
Setting positive end-expiratory pressure (PEEP) above the lower inflection point on the deflation part of the loop may help prevent inflated alveoli from collapsing and reexpanding with each breath.
