Study Notes
Mouth-to-Mouth Breathing Overview
- Mouth-to-mouth breathing offers a vital method to deliver oxygen in emergencies when barrier masks are unavailable.
- Each breath contains approximately 21% oxygen, while rescue breaths provide around 17% oxygen to the victim.
Adult and Child Rescue Steps
- Step 1: Utilize the head tilt-chin lift method to maintain an open airway. Pinch the victim's nose with your thumb and index finger while supporting the forehead.
- Step 2: Breathe normally and seal your lips around the victim’s mouth to create an airtight seal. Administer 1 breath for about 1 second, ensuring the chest rises.
- Step 3: If the chest does not rise, repeat the head tilt-chin lift and provide a second breath. If ventilation fails after 2 attempts, resume chest compressions immediately.
Infant Rescue Steps
- Step 1: Begin by opening the infant's airway using the head tilt-chin lift technique.
- Step 2: Cover both the infant’s mouth and nose with your mouth to form a proper seal.
- Step 3: Deliver one breath for about 1 second, observing for chest rise. If there is no rise, attempt to reseal the airway and provide another breath. If you cannot adequately cover both, revert to the mouth-to-mouth technique.
