If there was a sudden stop of breathing,the patient urgently needs artificial ventilation. Most often, such help is drowned people, hit by an electric shock, received a thermal or sunstroke. Also, this help may be necessary when strangling or severe poisoning. One way of ventilation is by mouth-to-mouth injection or "mouth to nose". Artificial ventilation is carried out until the victim is unable to breathe by himself. Of course, the air inhaled to a person contains about seventeen percent of oxygen instead of the usual twenty-one that a healthy individual breathes independently. However, this is enough to help the full-fledged.
So, if there were suspicions that the patientHas ceased to breathe, it is necessary to make immediately artificial breath, without losing precious time. When carrying out rescue operations for hygienic reasons, it is best to use a handkerchief or a piece of gauze, making (or biting) in the middle an opening of two to three centimeters. Then, with this slit, put the cloth on the patient's mouth and tighten his lips as close as possible to his lips. Through this opening, air will be injected.
For artificial ventilationis made correctly, the rescuer needs to rise to the left of the patient's head. If necessary, the oral cavity should be quickly cleared of vomit. In the event that the jaws were tightly compressed, they should be immediately expanded. After this, you need to throw back the victim's head, putting one hand on his head, and the other on his forehead. As a rule, the mouth opens.
Pre-rescuers need to do a deepinhale, then, bending over to the patient, completely seal his mouth with his lips. It is also necessary to pinch the nostrils of the injured person with the thumb and forefinger lying on his forehead.
Sometimes, by producing artificial respiration,the rescuer does not provide the necessary tightness, therefore, through the corners of the patient's mouth there is a leakage of air, and all efforts are in vain. Making sure that everything is done correctly, you need to quickly produce a strong exhalation in the respiratory tract of the victim. It should last about one second, its volume should be equal to 1 - 1.5 liters, to ensure the full stimulation of the respiratory center. Be sure to make sure that the patient's chest rises well when performing artificial inspiration.
The victim should exhalelasting about two seconds. At this time, the rescuer needs to take an inhalation one or two times to replenish his air reserves. Inflammation should be done at a frequency of twenty-five to thirty times per minute.
Artificial ventilation is producedby the method of "mouth to nose" in case there is a trauma to the jaws or lips, and also if the victim's teeth are tightly squeezed. One hand must be placed on his forehead, the other on his chin, bending his head and pressing his jaw lower to the top. Fingers supporting the chin, the rescuer needs to press the lower lip to ensure complete sealing of the patient's mouth. Having made the deepest inhalation, the rescuer covers the nose of the victim with his lips and heavily blows air through the nostrils. The movements of the patient's chest should be under constant control.
Of course, more effective impact onthe body is provided with an apparatus for artificial ventilation. It has a breathing bag with a gasket of porous rubber, as well as a mask. When using this device, the patient's head should be thrown back and put on the mask on the nose and mouth, and along with it, push the lower jaw forward. With one hand, the mask should be pressed tightly to the face in the nose with the thumb, and in the area of the chin - with the help of the index finger. The rest of the fingers of this hand are used to grip the chin in order to press the lower jaw to the top and hold it in the extended position. The second hand should press on the breathing bag to perform the inspiration, with the release of the hand is exhaled.
All rescue movements must be quick and collected, because this depends on the life of a person.
