CPR Airway & Breathing Management 3

Question 1

When using a bag-mask device with two rescuers, one person should:

Accepted Answer

Maintain a tight mask seal while the other squeezes the bag

Answer

Two-rescuer bag-mask ventilation works best with one maintaining the seal and the other squeezing the bag.

Question 2

What does the 'E-C clamp' technique refer to in bag-mask ventilation?

Accepted Answer

Hand position forming E and C to seal the mask

Answer

The E-C clamp uses the thumb and index finger as a 'C' to hold the mask and remaining fingers as an 'E' to lift the jaw.

Question 3

Excessive ventilation during CPR is harmful primarily because it:

Accepted Answer

Increases intrathoracic pressure and reduces blood return to the heart

Answer

Over-ventilation raises chest pressure, decreasing venous return and cardiac output.

Question 4

An oropharyngeal (OPA) airway should only be used in a patient who is:

Accepted Answer

Unresponsive with no gag reflex

Answer

An OPA can trigger vomiting or laryngospasm if a gag reflex is present, so it is only for unresponsive patients.

Question 5

How is the proper size of an oropharyngeal airway estimated?

Accepted Answer

Corner of the mouth to the angle of the jaw/earlobe

Answer

OPA size is measured from the corner of the mouth to the angle of the jaw or earlobe.
