Rescue Breathing
Rescue breathing is giving breaths to an unresponsive victim who has a pulse but is not breathing. you may provide rescue breathing by using a barrier device (eg, pocket mask) or bag- mask device. if emergency equipment is not available, the rescuer may provide breaths by using the mouth-to-mouth or mouth -to-mouth -and-nose technique.
Rescue Breathing for Adults-give 1 breath every 5 to 6 second (about 10 to 12 breaths per minute).
Rescue Breathing for infants and children- give 1 breath every 3 to 5 seconds (12 to 20 breath per minute)
Give each breath in 1 second.
Each breath should result in visible chest rise.
Check the pulse about every 2 minutes.
Technique for Giving Breath Without a barrier Device
Many cardiac arrest happen at home or other setting where rescue equipment is not available. this section describes techniques for giving breaths when you do not have a barrier device, such as a pocket mask or bag-mask device.
Mouth-to-Mouth Breathing for Adults and children
Mouth-to-Mouth breathing is a quick, effective technique used to provide oxygen to an unresponsive adult or child. follow these steps to give mouth-to-mouth breaths to adults and children:
STEPS
Hold the victim's airway open with a head tilt-chin lift.
Pinch the nose closed with your thumb and index finger using the hand on the forehead).
Take a regular (not deep) breath and seal your lips around the victim's mouth, creating an airtight seal.
Deliver 1 breath over 1 second, watch for thest to rise as you give the breath.
if the chest does not rise, repeat the head tilt-chin lift.
Give a second breath (blow for about 1 second). watch for the chest to rise.
if you are unable to ventilate the victim after 2 attempts, promptly return to chest compressions.
Breathing Techniques for Infants
The following techniques are used to give breath in infants
Mouth-to-Mouth-and-nose
Mouth-to-Mouth
The mouth-to -mouth-and-nose technique is preferred for infants. however, if you can't cover the infant's nose and mouth with your mouth, use the mouth-to-mouth technique instead.
Mouth-to-Mouth-and-nose
Maintain a head tilt-chin lift to keep the airway open.
place your mouth over the infant's mouth and nose and create an airtight seal.
blow into the infant's nose and mouth( pausing to inhale between breath). just enough to make the chest rise with each breath.
if the chest does not rise, repeat the head tilt-chin lift
