How reliable is the tidal volume measurement in predicting the type of lung disease present?
 
  a. Very reliable
  b. Somewhat reliable
  c. Not reliable
  d. Reliable but only in certain age groups

Question 2

During a helium (He) dilution functional residual capacity (FRC) measurement, the technologist first bleeds in 500 ml of He (He Vol) and obtains an initial reading of 4.0 (FiHe). After equili-bration, the second He reading is 3.2 (FfHe).
 
  What is the patient's FRC?
  a. 4450 ml
  b. 3125 ml
  c. 2680 ml

Answer to Question 1

ANS: C
Normal tidal volumes are often observed in both restrictive and obstructive lung diseases. There-fore, the VT alone is not a valid indicator of the type of lung disease.

Answer to Question 2

ANS: B
If the patient is connected to the circuit at the resting level, the FRC can be calculated with the following equation: FRC = (vol He  FiHe)  (FiHe  FfHe)  FfHe.
