Which of the following are acceptable means to help minimize the problems caused by condensa-tion in heated humidifier circuits?
 
  1. Installing water traps in the circuit
  2. Using a heated-wire circuit
  3. Setting heater temperature to 25 to 28 C
  a. 1, 2, and 3
  b. 2 and 3 only
  c. 1 and 2 only
  d. 1 and 3 only

Question 2

When using nebulizers, where should you place them to minimize risk of contamination?
 
  a. In the inspiratory limb only, at a high point in the circuit
  b. In both the expiratory and inspiratory limbs, at high points in the circuit
  c. In the expiratory limb only, at a low point in the circuit
  d. In both the expiratory and inspiratory limbs, at low points in the circuit

Answer to Question 1

ANS: C
One common method is to place water traps at low points in the circuit (both the inspiratory and expiratory limbs of ventilator circuits). The most common approach uses wire heating elements inserted into the ventilator circuit.

Answer to Question 2

ANS: A
To minimize this risk, place nebulizers in a superior position, so that any condensate travels downstream from the nebulizer.
