Why are rescue breaths encouraged when giving CPR to children and infants?
- Children's chests are too small and soft to receive any compressions
- Breaths replace the need to call 911 for a child
- Breaths are easier to give than compressions for a child
- Breaths plus compressions improve survival in children and infants
Mostra la risposta
Risposta: D. Breaths plus compressions improve survival in children and infants
For out-of-hospital cardiac arrest in infants and children, breaths plus compressions improve survival.

An AED for a 4-year-old has pediatric pads or a pediatric setting available. What should you do?
