Airway Management and Rescue Breathing Flashcards

What is the correct technique to open an unresponsive adult's airway before delivering rescue breaths?

Answer: Head-tilt chin-lift

The head-tilt chin-lift is the recommended technique for opening the airway in an unresponsive adult without suspected spinal injury.

When performing rescue breathing on an adult, how long should each breath be delivered?

Answer: About 1 second

Each rescue breath should be delivered over approximately 1 second to produce visible chest rise without over-inflating the lungs.

Which sign confirms that rescue breaths are being delivered effectively?

Answer: Visible chest rise with each breath

Visible chest rise with each breath confirms air is entering the lungs and rescue breaths are effective.

When should the jaw-thrust maneuver be used instead of the head-tilt chin-lift?

Answer: When a spinal injury is suspected

The jaw-thrust maneuver is preferred when a spinal injury is suspected because it opens the airway without extending the neck.

In hands-only CPR without rescue breaths, which victims are MOST likely to benefit from the addition of rescue breaths?

Answer: Children and drowning victims

Children and drowning victims experience respiratory arrest before cardiac arrest, so rescue breaths are especially important for oxygenating their blood.

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

Answer: 30:2

For single-rescuer adult CPR, the ratio is 30 compressions to 2 rescue breaths per cycle per AHA guidelines.

What should a rescuer do if the first rescue breath does not cause the chest to rise?

Answer: Reposition the airway and attempt a second breath

If the first breath does not produce chest rise, reposition the airway (retilt the head and lift the chin) before attempting a second breath.
