Explain how a heated High Flow Nasal Cannula system works. (2pts) Include details such as Fi02 range, flow range, heater, as well as how to adjust for both a worsening patient condition as well as improvements in patient conditions (weaning).

The highest FIO2 may be obtained from which of the following?

Oxygen tension below normal at the tissue level is:

Choose the following conditions that may be a response by the body to compensate for hypoxia: tachypnea  tachycardia increased cardiac output restlessness orthopnea

A venturi mask is likely to deliver a FIO2 higher than intended if:

Approximately how many hours will it take to empty an H cylinder of O2 that contains 1500 psi and is running at 10 Lpm?

You receive an order to check your patient’s SpO2 at 1530. This time is equivalent to:

At what point is humidity added to a patient’s nasal cannula?

A patient is receiving oxygen by venturi mask at 40% resulting in adequate oxygenation. The patient will not leave the mask on and quickly desaturates when the mask is off. Which of the following would be a viable alternative to attempt to achieve approximately the same level of oxygen?

A nasal cannula running at 3 Lpm assuming a normal breathing pattern will provide a delivered O2 concentration of approximately:
