  b. Increased compliance
  c. Decreased airway resistance
  d. Increased airway resistance

Question 2

Calculate the static compliance using the information from the pressure-volume loop below.
 
  a. 15 mL/cm H2O
  b. 20 mL/cm H2O
  c. 25 mL/cm H2O
  d. 30 mL/cm H2O

Question 3

What is the flow-cycle setting for the pressure support ventilation (PSV) breaths shown in the scalars below?
 
  a. 10
  b. 25
  c. 40

Answer to Question 1

ANS: A
The volume delivered remains the same for both the loops. However, the pressure has increased from approximately 20 to 35 cm H2O. The alveolar pressure (PA) has increased also. This is indic-ative of a decrease in compliance.

Answer to Question 2

Answer to Question 3

ANS: D
The peak inspiratory flow is 40 L/min. Inspiration ends at 20 L/min. The flow cycle is therefore set at 50.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
