A sudden drop in blood pressure deprives the brain's neurons of oxygen, causing a deep syncopal state. Unconsciousness is accompanied by a sharp relaxation of skeletal muscles, which carries a direct threat of severe traumatic brain injuries when hitting a hard surface.
Timely restoration of cerebral blood flow blocks tissue necrosis and prevents the development of hypoxic coma. The pre-medical algorithm requires strict monitoring of the patency of the respiratory tract and the correct positioning of the victim's body before the arrival of the intensive care unit.
Assessment of basic reflexes and opening of the respiratory tract
The first stage of rescue operations is palpation of the carotid artery to fix the heart rhythm. Tilting the head back with a slight extension of the lower jaw tightens the neck muscles and prevents the root of the tongue from sinking into the larynx.
In the presence of rhythmic excursions of the chest, it is necessary to immediately remove mechanical resistance for free blood circulation. Easing the pressure on the cervical veins reduces intracranial pressure and accelerates the return of plasma to the right atrium.
To stabilize the gas exchange, perform the following manipulations:
- undo the top buttons of your shirt and remove the stiff tie;
- loosen the leather waist belt or unlace the tight corset;
- open the windows in the room to reduce the concentration of carbon dioxide.
The elimination of external compression of the diaphragm triggers the process of complete blood oxygenation. The victim must be in a strictly horizontal position on flat asphalt or hard flooring.
Techniques for stimulating peripheral blood circulation
The gravitational redistribution of fluids is the main tool for removing a person from deep hypoxia. The elevation of the lower extremities by 30-40 centimeters above the level of the myocardium provides a hydrostatic discharge of venous blood from the calf muscles to the main vessels.
An increase in the volume of circulating blood in the thoracic aorta increases the pressure in the carotid arteries by 15-20 millimeters of mercury. Neurons receive a fresh dose of oxygen, which triggers the activation of the reticular formation of the brain stem.
The effect on nociceptive receptors accelerates the exit from syncope:
- bring a gauze swab with an ammonia solution to a distance of 5 cm from the nose;
- rub the earlobes with intense circular movements of the phalanges of the fingers;
- moisten your face with cold water for a sharp spasm of peripheral capillaries.
Handling corrosive ammonia vapors requires strict adherence to a safe distance. Close contact of the chemical with the mucous membrane of the nasal passages provokes a reflex spasm of the bronchi and a chemical burn of soft tissues.
Critical errors in pre-medical procedures
The verticalization of a person immediately after opening the eyes provokes an immediate orthostatic collapse. Vascular tone is restored smoothly, so the patient needs to lie down for at least 10 minutes after the return of stable speech contact.
Attempts to put the victim on a chair force the heart to work against the gravity vector. A weakened heart muscle cannot cope with pumping blood upward, which leads to repeated and prolonged cerebral cortex ischemia.
The infusion of liquids into the oral cavity with a suppressed swallowing reflex ensures the aspiration of water into the respiratory tract. With laryngeal spasm, fluid penetrates the trachea, triggering the mechanism of severe aspiration pneumonia.
Slashing blows to the cheeks do not stimulate the vagus nerve, but only form deep subcutaneous hematomas on the face. If the pulse on the main arteries is not felt for more than two minutes, the protocol requires an immediate transition to chest compressions.
