Question

12-14

12. Why would a bubble humidifier not provide adequate humidification for a patient with a tracheostomy tube in place? Provide two reasons. 13. Humidifier #1 has a large diffuser head and produces small bubbles. Humidifier 2 has a small diffuser head and produces large bubbles. Which will provide the best humidification Explain your answer. 14. Setup the disposable bubble humidifier with your nasal cannula and practice placing on your partner at 6 LPM. What occurs when the oxygen tubing becomes completely occluded (manually kink tubing)?

Answer 1

1. Ist reason- exhibit high resistance to airflow imposing higher work of breathing.

2.2nd reason- humidifying capacity is low and Whenever high flow rates (usually in
excess of 10 L/min) are used, bubble humidifiers
can produce aerosols. These water droplets can
transmit pathogenic bacteria from the humidifier
reservoir to the patient.

13. Humidifier #1 with a large diffuser head and small bubbles will provide the best humidification because The smaller the bubbles, the larger the gas-water interface allowing for higher water vapor content And the greater the surface area of the diffuser the more the evaporation.

14.when the oxygen tubing becomes fully occluded then
there is a risk that the pressure
relief valve becomes dysfunctional, which can lead
to the build-up of excessive pressures and burst
the humidifier bottle whenever a flow obstruction occurs.
