Answer 2

The amount of air that enters the lungs during the recoil phase of chest compressions

Question 3

this results in _____ intrathoracic presssure

Answer 3

Negative

Question 4

Negative intrathoracic pressure caused by impedance threshold device is good because it ________

however, the impedance threshold device can be used with devices that

Answer 6

Devices that Provide active compression decompression CPR

Question 7

What is one instance where the impedance threshold device should be removed?

Answer 7
