CPR Techniques 3

Question 1

When giving rescue breaths, how long should each breath last?

Accepted Answer

About 1 second

Answer

Each rescue breath should be delivered over about 1 second and produce visible chest rise.

Question 2

What is the proper head position to open the airway in an unresponsive adult with no suspected spinal injury?

Accepted Answer

Head-tilt, chin-lift

Answer

The head-tilt, chin-lift maneuver opens the airway in adults without suspected neck injury.

Question 3

If the first rescue breath does not make the chest rise, what should you do?

Accepted Answer

Reposition the head and try again

Answer

Re-tilt the head to reopen the airway and attempt the breath once more.

Question 4

What airway technique is preferred when a spinal injury is suspected?

Accepted Answer

Jaw-thrust without head tilt

Answer

The jaw-thrust maneuver opens the airway while minimizing neck movement.

Question 5

During mouth-to-mouth ventilation, what must you do to prevent air from escaping?

Accepted Answer

Pinch the victim's nose closed

Answer

Pinching the nose ensures air enters the lungs rather than escaping through the nostrils.
