Upon arrival to the emergency department, a patient is found to have an SpO2 of 75% on a non-rebreathing mask. You notice that the nonrebreathing mask is hooked to a bubble humidifier
The humidifier bottle is whistling and is expanded. What is your next action as the respiratory therapist?
a. Change the bubble humidifier; it's defec-tive.
b. Check for kinks in tubing.
c. Remove the nonrebreathing mask from the humidifier and run off of O2.
d. Place a Venturi mask on the patient.
ANS: C
The humidity bottle is not designed for high flows. When it is set to a high flow, the humidity bottle expands and whistles; in turn there is a greater likelihood that the oxygen flowmeter will pop off from the pressure source.
