3. Physiopathology bases of reanimation

Essence and technics of actions reanimation. Actions on revival should be started immediately, remembering that the bark of a brain in conditions normothermie can transfer clinical death no more than 5-6 minutes.

1. The victim stack on a rigid surface, clothes unbutton (cut) and remove.

2. On area of the bottom third of brest make rhythmic pressing by two palms imposed against each other in beat 40-60 in one minutes. These pressing jerky to squeeze a thorax it should be necessary not so much due to force of hands, how many due to weight of a trunk. At the closed massage the thorax should to condense on 5-7 sm; duration of a push of 0,7-0,8 seconds. At each pressing on a brest there is a compression of heart between a brest and a backbone that results in exile of blood in an aorta and an pulmonary artery. Thus it is possible is long to support of blood recycling, sufficient for preservation of viability of an organism if thus it is possible to support arterial pressure at a level not less than 70 mm of a hg.

If indirect massage of heart is inefficient, pass to direct which demands opening a thorax, therefore it s carried out by doctors - experts in well equipped operational where there are devices of artificial ventilation easy, defibrillators etc.

3. An essential component of reanimation is intraarterial in the direction of heart a forcing of blood with glucose and adrenaline, peroxide of hydrogen and vitamins. It provides irritation of angioreceptores and reflexly promotes restoration of intimate reductions. Besides the coronary blood-groove and receipt of nutrients to a myocardium is restored, that also promotes restoration retractileness of hearts. As soon as heart is started, the intraarterial forcing of blood stops.

In case of development of fibrillation carry out of electric defibrillation in the way of gear transmission during 0,01 second an electric current a voltage from 2 up to 7 thousand volt (in essence it is the category of the condenser between which plates there is a patient) that synchronizes muscular reductions, eliminating fibrillation.

All listed actions should be combined with artificial ventilation easy " a mouth in a mouth " or " a mouth in a nose ", that gives receipt of oxygen, and a stretching of pulmonary fabric reflexly promotes restoration of activity of the respiratory center. With this purpose a head of the victim as much as possible throw back, reanimated, rendering the help, one hand is opened with a mouth, and another clamps a nose to the victim. Then having pressed the lips to lips of the patient, makes a sharp breath in him until the thorax of the victim will not start to rise, and removes a head aside. The victim has exhalation. This procedure repeat with frequency about 20 times one minute.

If jaw are strong compressed, use breath " a mouth in a nose ", closing a mouth of the victim. From hygienic reasons artificial breath carry out through a gauze or a handkerchief. Can be used and air lines. An exhalation carry out at the moment of the pressing termination on a brest. Usually one breath is carried out after 5-6 pressings on a brest. Carrying out of artificial massage of heart in a combination to artificial ventilation easy demands, except for high professionalism, the big physical expenses.

Criteria of reanimation efficiency :

1. Occurrence of pulse on sleepy and beam arteries.

2. Reduction of a cyanosis degree . Narrowing up to that the expanded pupils.

3. Increase of arterial pressure up to 60-70 mm of a hg and is higher.

How long necessary to carry out reanimation? In the literature cases of successful revival of an organism after 3-8 hours of continuous massage of heart and artificial breath are described.
