Study Notes
Giving CPR (Adults)
- Press downward to depress the breastbone to a depth of at least 2 inches (5 cm) during chest compression, while avoiding excessive chest compression depths (greater than 2.4 inches, or 6 cm).
- Release the pressure but do not remove your hands from the chest after compressing.
Giving Rescue Breaths
- Pinch the nose and tilt the chin before placing your mouth over the victim's mouth.
- Give the victim two rescue breaths.
CPR Cycles
- Continue giving cycles of 30 chest compressions and two rescue breaths until help arrives.
- Repeat the cycles until help arrives.
CPR Guidelines
- Check for signs of circulation.
- If signs of circulation are present but there is no normal breathing, provide rescue breathing at:
- 1 breath every 6 seconds (about 10 breaths per minute) for adults.
- 1 breath every 2-3 seconds (20-30 breaths/minute) for children.
- If no signs of circulation are present, begin the cycles of chest compressions.
