Which of the following reduce the risk of nosocomial infection when using heated humidifica-tion systems?
 
  1. Use of wick or membrane humidifiers
  2. Use of heated-wire delivery circuits
  3. High humidifier reservoir temperatures
  4. Frequent changing of delivery circuits
  a. 1 and 3 only
  b. 1, 2, and 3 only
  c. 3 and 4 only
  d. 2, 3, and 4 only

Question 2

In checking a servo-controlled heated-wire humidifier system, you notice that a few drops of condensate tend to form but only near the patient's airway. Based on this observation, what can you conclude?
 
  a. The gas at the airway is fully saturated.
  b. The temperature setting of the heater is too high.
  c. The airway temperature exceeds the dew point.
  d. The temperature setting of the heater is too low.

Answer to Question 1

ANS: B
It is now known that frequent ventilator-circuit changes actually increase the risk of nosocomial pneumonia.

Answer to Question 2

ANS: A
To ensure that the inspired gas is being properly conditioned, clinicians should always adjust the temperature differential to the point that a few drops of condensation form near the patient wye. Lacking direct measurement of humidity, observation of this minimal condensate is the most reliable indicator that the gas is fully saturated at the specified temperature.
