The typical pressure pop-off incorporated into most simple bubble humidifiers releases pressure above which of the following?
 
  a. 760 mm Hg
  b. 10 cm H2O
  c. 250 kPa
  d. 2 psig

Question 2

Why should you not heat the reservoirs of a bubble humidifier used with an oronasal O2 delivery system?
 
  a. Condensate will obstruct the delivery tubing.
  b. Heating will melt the reservoir or cause a fire.
  c. Heating will absorb the extra water vapor.
  d. Heating will cause too much aerosol im-paction.

Answer to Question 1

ANS: D
Typically, the pop-off is either a gravity or spring-loaded valve that releases pressures above 2 psig.

Answer to Question 2

ANS: A
Heating the reservoirs of these units can increase humidity content but is not recommended be-cause the resulting condensate tends to obstruct the small-bore delivery tubing to which they connect.
