Variable-Flow-Rate Oxygen

Question 4

CRITICAL FACT

Answer 4

Oxygen cylinders have U.S.P. and are yellow diamond labels that make them easy to recognize. In the United States, oxygen cylinders typically have green markings.

Question 5

Answer 9

is used only on breathing patients and delivers oxygen through the patient’s nostrils. A plastic tube is held in place over the patient’s ears, and oxygen is delivered through two small prongs inserted into the nostrils.

Question 10

Resuscitation mask with Oxygen inlet

Answer 10

Can be used with emergency oxygen to deliver oxygen to a non breathing patient, it can also be used to deliver emergency oxygen to someone who is breathing but still requires oxygen.

Question 11

Non-rebreather mask

Answer 11

is used to deliver high concentrations of oxygen to breathing patients. It consists of a face mask with an attached oxygen reservoir bag and a one-way valve between the mask and bag to prevent the patient’s exhaled air from mixing wight he oxygen in the reservoir bag. Inhales air from bag, exhales through flutter valves.
