LIFEGUARDING OXYGEN EXAM QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
What happens when an unconscious person's chest doesn't rise when giving ventilations? - Answers
His airway is obstructed
So what are the steps for an unconscious person choking? - Answers Give 30 chest compressions
then check for object in Victim's mouth. If object is not found, give two ventilations and repeat the
process and use your finger to dislodge object.
Hypoxia - Answers Insufficient amount of oxygen reaches the cells.
What percent is the oxygen humans breathe? How many percent is givin during ventilation? -
Answers 21 Percent, 16 percent.
Giving emergency oxygen to an adult for: - Answers An adult breathing 12 or more than 20 breaths
per minute.
Giving emergency oxygen to a child for: - Answers A child breathing 15 or more than 30 breaths per
minute
Giving Emergency oxygen to an infant for: - Answers An infant breathing fewer than 25 or more than
50 breaths per minute.
How should oxygen should be appropriately given? - Answers It has to be properly sized for the
victim and flow rates that are appropriate for the delivery device.
What are the specifications for emergency oxygen units that are for First-aid use? - Answers They
contain a 15 minute supply of oxygen and have a pre=set rate of at least 6 liters per minute.
How are oxygen cylinders labeled? - Answers They are labeled U.S.P. with a yellow diamond
containing the word "Oxygen". U.S.P. stands for United States Pharmacopeia.
What is the common oxygen cylinder type and how is it used? - Answers The common cylinder uses a
variable-flow-rate oxygen, which allows the user to vary the flow of oxygen.
How to assemble a variable flow rate oxygen? - Answers Assemble the pieces: an oxygen cylinder, a
regulator with pressure gauge, flowmeter, and a delivery device.
The regulator does what? - Answers The regulator lowers the pressure of the oxygen, so that it can
be used safely.
What does the regular also contain? - Answers The regulator also shows the pressure in the cylinder.
What is considered full on the pressure gauge in a cylinder? - Answers 2000 pounds per psi
The regular must be what? - Answers Must be attached carefully to the oxygen cylinder.
What does an o-ring do? - Answers The o-ring gasket makes the seal tight.
The Flow-meter in a variable-flow-rate does what? - Answers controls how rapidly oxygen flows from
the cylinder to the victim. It can be set from 1 to 25 LPM
Some emergency oxygen systems have a what on a fixed-flow rate? And what is it commonly set too?
- Answers Regulator, and it is mostly set at 15 LPM.
What are the other fixed-flow rate tanks set as? - Answers Set between 6 to 12 LPM
What is typical with a fixed-flow rate? - Answers Their delivery device, regulator, and cylinder are
already assembled.
What are some draw backs on a fixed flow rate? - Answers A draw back is that the flow rate cannot
be adjusted, which limits the concentration of oxygen that can be delivered.
How do I operate a fixed-flow rate delivery device? - Answers Simply turn it on according to the
manufacturer's instruction, check if oxygen is flowing and place the delivery device on the victim.
