QUESTIONS WITH CORRECT ANSWERS
VERIFIED GRADED A+
⩥ What is the rate of compressions for adults, children and infants?
Answer: The UNIVERSAL rate for all in cardiac arrest is 100 - 120
bpm.
⩥ What is the compression-to-ventilation ratio for single rescuers with
adults, children and infants?
Answer: 30:2
⩥ What is the compression-to-ventilation ratio for 2 rescuers with adults,
children and infants?
Answer: adults = 30:2
children = 15:2
infants = 15:2
⩥ What is the hand placement for compressions in infants?
Answer: 2-finger technique (2 fingers vertically, just below the nipple
line); don't press on the xiphoid process
,2 thumb-encircling hand technique (place both thumbs side-by-side in a
horizontal fashion, thumbs may be placed on top of each other with very
tiny infants)
⩥ Does the 2-finger technique or 2 thumb-encircling hand technique
produce greater blood flow?
Answer: 2 thumb-encircling hand technique
⩥ This compression technique is recommended for infants when CPR is
provided by 2 rescuers as it:
*produces better supply to the heart muscle
*helps ensure consistent depth and force of chest compressions
*may generate higher blood pressures
Answer: 2 thumb-encircling hands technique
⩥ Why is it especially important to provide rescue breathing to children
and infants in cardiac arrest?
Answer: When SUDDEN cardiac arrest occurs, the oxygen content of
the blood is typically adequate to meet oxygen demands of the body for
the first few minutes after arrest. So delivering chest compressions is an
effective way of distributing oxygen to the heart and brain.
In contrast, infants and children often have respiratory failure or shock
BEFORE a cardiac arrest which reduces the oxygen content of the
blood. Chest compressions for children and infants won't be adequate by
, themselves. Rescue breathing must happen in addition to chest
compressions for CPR to be effective.
⩥ What is the correct compression-to-ventilation ratio for a single
rescuer of a 3-year-old child?
a. 15:1
b. 15:2
c. 20:2
d. 30:2
Answer: d. 30:2
⩥ What is the correct compression-to-ventilation ratio for a 7 yo when 2
or more rescuers are present?
a. 15:1
b. 15:2
c. 20:2
d. 30:2
Answer: b. 15:2
⩥ For what age victim is the 2 thumb-encircling hands technique
recommended when 2 or more rescuers are present?
