Question

your adult friend suddenly collapses at home, and you determine she needs cpr. you begin cpr, starting with chest compressions, and are about to deliver breaths by using mouth - to - mouth breaths. you open the airway with a head tilt - chin lift.
what is the sequence of your next actions?
give 1 breath and blow for about 1 second
give a second breath (blowing for about 1 second, watching for chest rise)
watch for chest rise while giving the breath
pinch the nose and seal your lips around the victims mouth

Explanation:

When performing mouth - to - mouth breaths in CPR:

• First, pinch the nose and seal your lips around the victim's mouth to create an airtight seal. This is essential to prevent air from escaping through the nose and ensure that the air you blow goes into the victim's lungs.
• Then, give 1 breath and blow for about 1 second while watching for chest rise. Watching for chest rise confirms that the breath is effective and the air is entering the lungs.
• Next, give a second breath (blowing for about 1 second, watching for chest rise). Two breaths are given in sequence as part of the rescue breathing cycle in CPR.

Answer:

1. Pinch the nose and seal your lips around the victim's mouth
2. Give 1 breath and blow for about 1 second, watch for chest rise
3. Give a second breath (blowing for about 1 second, watching for chest rise)
