Question 1

What is a device called that provides a precise oxygen concentration between 21% and 100% by mixing air and oxygen?

Accepted Answer

An air/oxygen blender is a device that provides a precise oxygen concentration by mixing air and oxygen.The concentration may be adjusted to any value from room air to 100% oxygen.

Question 2

A patient needs to be transported from the emergency department to the ICU on a 50% Venturi mask.What oxygen equipment is needed for you to accomplish the transport?

Accepted Answer

The answer of A patient needs to be transported from...

Question 3

You attach a pressure reducing valve to a 'M' sized gas cylinder.When you open the cylinder valve you hear gas leaking from of near the valve-cylinder connection.What should you do?

Accepted Answer

The answer of You attach a pressure reducing valve to...

Question 4

A device that reduces the pressure in the medical gas cylinder from 2200 psi to 50 psi is termed a ________________

Accepted Answer

A device that reduces the pressure in the medical gas cylinder from 2200 psi to 50 psi is termed a reducing valve.

Question 5

You are going to transport a patient to the MRI department for a MRI scan.The patient is on a non-rebreathing mask at 15 LPM.The procedure will last approximately 60 minutes.What equipment should the practitioner gather for the transport?

Accepted Answer

The answer of You are going to transport a patient...

Question 6

What device takes air from the atmosphere and separates the oxygen from the other gases in the air,then delivers the oxygen to the patient at as high as 90% concentration?

Accepted Answer

An oxygen concentrator provides an adequate oxygen concentration of between 40% to 90%,depending on the type of unit.

Question 7

If a cylinder needs to be placed in the horizontal position for a transport,which type of flowmeter would be the best to use?

Accepted Answer

A Bourdon gauge flowmeter may also be referred to as a fixed orifice flowmeter.This flowmeter is really not a flowmeter at all but rather a pressure gauge calibrated to measure flow.These flowmeters will operate in any position.

Question 8

What is the purpose of 'cracking' a cylinder before use?

Accepted Answer

Before attachment of any equipment to a cylinder,the cylinder valve must be cracked.Cracking the cylinder removes any dust,or particulate matter,from the outlet of the cylinder valve.This prevents contaminants from entering any equipment.If the materials are flammable,fire hazard is minimized because contaminants are removed before the application of high-pressure oxygen.
