carotid or femoral artery

Question 14

Compression depth of child BLS

Answer 14

at least 2 inches

Question 15

Compression rate of child BLS

Answer 15

100-120 per minute

Question 16

Compression to ventilation rate of child BLS

Answer 16

30: 2 with 1 rescuer
15: 2 with 2 rescuers

Question 17

Number of ventilations in child BLS

Answer 17

1 breath every 6 seconds

Question 18

active compression- decompression CPR

Answer 18

compressing the chest and then actively pulling it back up to its neutral position or even beyond to increase amount of blood that returns to the heart and thus, increases amount of blood ejected from the heart during compression phase

Question 19

chest compression fraction

Answer 19

total percentage of time during a resuscitation attempt in which active chest compressions are being performed

Question 20

impedance threshold device (ITD)

Answer 20

valve device placed between endotracheal tube and a bag valve mask that limits amount of air entering the lungs during the recoil phase between chest compressions

Question 21

ischemia

Answer 21

lack of oxygen that deprives tissues resulting in partial or complete blockage of blood flow; potentially REVERSIBLE

Question 22

ROSC

Answer 22

return of spontaneous circulation i.e. return of a pulse and effective blood flow to the body in someone who was previously in cardiac arrest
