Answer to Question 1

ANS: D
Condensation can disrupt or occlude gas flow through the circuit, potentially altering FiO2 and/or ventilator function. Moreover, condensate can work its way toward the patient and be aspirated. For these reasons, circuits must be positioned to drain condensate away from the patient and must be checked often, and excess condensate must be drained from heated humidifier breathing circuits on a regular basis. Typically, patients contaminate ventilator circuits within hours, and condensate is colonized with bacteria and thus poses an infection risk. To avoid problems in this area, health care personnel should treat all breathing-circuit condensate as infectious waste.

Answer to Question 2

ANS: D
Factors influencing the amount of condensation include (1) the temperature difference across the system (humidifier to airway), (2) the ambient temperature, (3) the gas flow, (4) the set airway temperature, and (5) the length, diameter, and thermal mass of the breathing circuit.
