Airway & Breathing Management Flashcards

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

Answer: Maintain a tight mask seal while the other squeezes the bag

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

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

Answer: Hand position forming E and C to seal the mask

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.

Excessive ventilation during CPR is harmful primarily because it:

Answer: Increases intrathoracic pressure and reduces blood return to the heart

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

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

Answer: Unresponsive with no gag reflex

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

How is the proper size of an oropharyngeal airway estimated?

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

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

Once an advanced airway is in place, rescuers should give ventilations at a rate of:

Answer: 1 breath every 6 seconds

With an advanced airway, give continuous compressions and one breath every 6 seconds (10 per minute).

A nasopharyngeal airway is most appropriate for a patient who:

Answer: Has an intact gag reflex but needs airway support

An NPA is tolerated by patients with a gag reflex but should be avoided with suspected basal skull fractures.
