A client has been placed on 6 L of humidified oxygen via nasal cannula. Which action by the nurse is most appropriate?
a. Drain condensation back into the humidifier, maintaining a closed system.
b. Keep the water sterile by draining it from the water trap back into the humidifier.
c. Turn down the humidity when condensation begins to collect in the tubing.
d. Remove condensation in the tubing by disconnecting and emptying it appropriately.
D
Condensation often forms in the tubing when a client receives humidified high-flow oxygen. Remove this condensation as it collects by disconnecting the tubing and emptying the water. Some humidifiers and nebulizers have a water trap that hangs from the tubing so the condensation can be drained without disconnecting. To prevent bacterial contamination, never drain the fluid back into the humidifier or the nebulizer. Do not turn down the humidity because the physician has ordered it and the client needs it. Minimize how long the tubing is disconnected because the client does not receive oxygen during this period.
