what is the purpose of mouth to mouth resuscitation
Mouth-to-mouth resuscitation Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body, where a rescuer presses his or her mouth against that of the victim and blows air into the person's lungs.[1][2] Assistance takes many forms, but generally entails providing air for a person who is not breathing or is not making sufficient respiratory effort on his/her own.[3] It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration).
Cardiopulmonary resuscitation CPR is indicated for any person unresponsive with no breathing or breathing only in occasional agonal gasps, as it is most likely that they are in cardiac arrest.[6]:S643 If a person still has a pulse but is not breathing (respiratory arrest) artificial ventilations may be more appropriate, but, due to the difficulty people have in accurately assessing the presence or absence of a pulse, CPR guidelines recommend that lay persons should not be instructed to check the pulse, while giving healthcare professionals the option to check a pulse.[7] In those with cardiac arrest due to trauma, CPR is considered futile but still recommended.[8] Correcting the underlying cause such as a tension pneumothorax or pericardial tamponade may help.[8]
Swallowing 5) Closure of the nasopharynx
Cardiopulmonary resuscitation Cardiopulmonary resuscitation (CPR) is an emergency procedure that combines chest compressions often with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is recommended in those who are unresponsive with no breathing or abnormal breathing, for example, agonal respirations.[1]
