American Red Cross Lifeguarding Exam
Questions With Complete Solutions
what is the amount of oxygen that you exhale into a victim using only your pocketmask?
35-55%
what is the amount of oxygen given to a victim using a BVM without oxygen?
Up to 90%
what is the amount of oxygen given to a victim using a BVM hooked up to oxygen?
90% or higher
What are some signs of hypoxia?
increased breathing & heart rates, changes in LOC, restlessness, chest pain, cynosis
LOC
Level of consciousness
cynosis
tissue doesnt get enough oxygen; victim turns blue.
What are the breathing rates for an adult?
12-20 bpm
BPM
breaths per minute
What are the breathing rates for a child?
15-30 bpm
What are the breathing rates for an infant?
25-50 bpm
What if breathing rate is above or below normal rates?
administer emergency breathing
When placing mask on victim, what is the proper placement?
For adults, you want the narrow part over the nose and the rim (bottom part) over the chin. Same for
children. But for infants, the sides are reversed.
What is the best method to determine that breaths given by a BVM are effective?
check for chest rise and fall, rise in oxygenation, and change in color.
, You and another rescuer arrive on the scene and are about to give breaths using BVM. You just sealed
the mask. Whats next?
make sure head is in proper alignment
What is the flow rate for nasal cannula?
1-6 LPM
LPM
Liters per minute
What is the flow rate for resuscitation mask?
6-15 LPM
What is the flow rate for a non-rebreather mask?
10-15 LPM
BVM
Bag-Valve Mask
What is the flow rate for a BVM?
15LPM or higher
What do you use to set LPM?
with a variable-flow-rate oxygen system, turn the FLOWMETER to suggested L.P.M
how do you determine oxygen is flowing?
Listen for a hissing sound and feel for oxygen flow through the delivery device.
What will interfere with the accuracy of a pulse oximeter reading?
shock, cardiac arrest, excessive motion of patient during reading, carbon monoxide poisoning,
fingernail polish, hypothermia or other other cold related emergency, sickle cell anemia, cigarette
smokers, swelling, time lag detection of repiratory insufficiency
Pulse oximeter (the finger box thing)
used to measure percentage of oxygen saturation in the blood.
What should you do when the oxygen cylinder reaads 200 lbs per sq. inch?
do not use. you want the pressure gauge to read more than 200 psi
What should you do when the oxygen cylinder reaads 800 lbs per sq. inch?
its ok to use
What pulse oximeter reading indicates possible hypoxia?
94% and below. 91-94 is mild, 86-90 is moderate, less than 85 is severe
