A physician orders 53% O2 through an air-entrainment nebulizer to a patient with a tidal volume of 0.575 Liters and a respiratory rate of 20 breaths/min. The maximum nebulizer input flow (flow meter setting) is 12 L/min. What is the air to 02 ratio? What is the total flow? What is the patient’s peak inspiratory flow? Does this device meet the patients’ needs?

On low flow oxygen systems, a number of variables can affect FI02. What are some things that increase Fio2? Select all that may apply.

What medical gas cylinder is represented in the US and Canda with the color gray?

Many medical gases are nonflammable or supports combustion. A gas that is nonflammable does not burn.

List 2 common problems with low-flow O2 delivery systems.

A partial rebreathing mask prevents rebreathing with one-way valves.

The RT needs to determine how long a G cylinder of O2 with a gauge pressure of 1800 psi set to deliver 12 L/min will last until empty.

Which of the following is an example of an anecdotal description?
