The mouth to mouth or mouth to nose technique of Artificial Respiration in the absence of equipment is the most practical method foe emergency ventilation of a person of any age who has stopped breathing, regardless of why breathing has stopped. The mouth to mouth and mouth to nose resuscitation are unequivocally superior to any of the manual techniques.
The mouth to mouth, mouth to nose techniques provides more ventilation that the other methods using direct air pressure exerted by the rescuer to obtain more accurate information on the volume, pressure and timing of efforts needed to inflate the victim’s lungs that is afforded by other methods. Another advantage of this method of Artificial Respiration aside from its effectiveness in ventilating the lungs is that it may be given in the water, in a boat underneath wreckage, and in other place where immediate resuscitation might be necessary. The manual methods of Artificial Respiration are chiefly of historical interest because they are not as effective as the mouth to mouth and nose to mouth method.
