CAB stands for Compressions, Airway, Breathing, prioritizing compressions first.
Question 2: When giving rescue breaths, how long should each breath last?
- About 1 second (Correct answer)
- About 5 seconds
- About 3 seconds
- Less than half a second
Correct answer: About 1 second
Each rescue breath should last about 1 second and produce visible chest rise.
Question 3: What is a sign that a rescue breath was effective?
- The chest visibly rises (Correct answer)
- The stomach expands
- The victim coughs

Visible chest rise indicates the breath reached the lungs.
