Airway Management & Ventilation Flashcards

When performing a head-tilt chin-lift on an adult, where should you place your fingers to lift the chin?

Answer: On the bony part of the lower jaw

Fingers should be placed on the bony part of the lower jaw to lift the chin without compressing the soft tissue, which could obstruct the airway.

A bag-mask device should deliver approximately how much air volume per breath to an adult?

Answer: 400–600 mL

Each breath should deliver approximately 500–600 mL (roughly 400–600 mL range), enough to produce visible chest rise without causing gastric inflation.

Which of the following is a sign that rescue breaths are being delivered correctly?

Answer: The patient's chest visibly rises with each breath

Visible chest rise with each breath confirms air is entering the lungs rather than the stomach.

In an unresponsive adult patient with no suspected spinal injury, which maneuver is preferred to open the airway?

Answer: Head-tilt chin-lift

The head-tilt chin-lift is the preferred airway maneuver for unresponsive patients without suspected spinal injury.

How long should each rescue breath be delivered during CPR?

Answer: About 1 second

Each breath should be given over about 1 second, which is enough to produce chest rise without causing excessive gastric inflation.

What is the correct compression-to-ventilation ratio for a single rescuer performing adult CPR?

Answer: 30:2

For adult CPR with one or two rescuers, the recommended compression-to-ventilation ratio is 30:2.

When using a bag-mask device with two rescuers, how should the mask be held?

Answer: Both hands on the mask forming an E-C clamp while the second rescuer squeezes the bag

With two rescuers, one forms an E-C clamp with both hands to maintain a mask seal while the second rescuer squeezes the bag, improving ventilation effectiveness.
