Breathing is the process of inhaling and exhaling air in order to oxygenate the body's tissues. In CPR, the ability to breathe is assessed by checking for the presence of air movement, chest rise and fall, and the sound of breath. If a person is not breathing, rescue breathing may be necessary to provide oxygen to the body.
Breathing is a critical component of cardiopulmonary resuscitation (CPR). Assessing breathing, providing oxygen, and managing the airway are all important steps in providing effective CPR.
If the victim has a pulse but not breathing, you need to open the airway by doing a head tilt, chin lift, or jaw thrust maneuver if the victim has a spine injury. Then pinch the nose shut and give the first rescue breath, lasting for 1 second. The correct ventilation rate for adults is 10 to 12 breaths per minute. Ensure the chest rises and falls with each breath.
If the victim's chest doesn't rise when you give the first rescue breath, ensure the airway is open by doing the head tilt chin lift again before you give the 2nd rescue breath. If the chest still doesn't rise, stop giving rescue breath and perform chest compressions only. The chest compression rate for adults is 100-120 compressions per minute.
Yes, giving an entire full breath to an adult victim is necessary to make the chest rise and fall. But make sure that the breath you give lasts only 1 second. Excessive ventilation or going too fast could push air into the stomach, resulting in gastric insufflation. So it's important to follow the correct ventilation rate of 10 to 12 breaths per minute.
You need to assess the breathing and pulse of the child to determine what actions to give. If the child has a pulse but is not breathing, provide rescue breaths only. If the child has no pulse and is not breathing, provide CPR starting with chest compressions followed by 2 rescue breaths. If you are not trained in CPR or confident in giving rescue breathing, you can perform Hands-Only CPR.
