Asphyxia is a life-threatening condition of acute or subacute lack of oxygen in the blood and an excess of carbon dioxide in the body, which is manifested by a violation of the activity of the nervous system, respiration and circulation. In acute asphyxia, death in the event of failure to provide first aid can occur in 3-6 minutes.
Causes of suffocation.
The most common cause of asphyxiation( breathlessness) is the mechanical obstruction of access to airways in the respiratory tract when they are compressed from the outside( for example, accidental ingestion of food in the respiratory tract, fluid( when popperhivanii, while talking during meals), vomit, foreign bodies, withviolent strangulation of hands, a loop, etc., when drowning).Asphyxia can be caused by inflammatory processes of the larynx( for example, diphtheria), language Westernization with unconscious states, laryngeal tumors, spasm of the glottis, poisonous substances( some poisons, ether, carbon monoxide), lack of oxygen in the room, p
First aid for suffocating.
Calm the person and everyone around him. Extra noise can provoke a spasm of the airways.
If possible, ensure the termination of the factor causing choking( eg, poison).
Unbutton the shirt collar.
If possible, move the victim to a convenient place.
When cardiac arrest, it is urgent to begin external heart massage;when breathing is stopped - to artificial respiration( see Resuscitation), and also call an ambulance.
Immediately apply Heimlich's method with accidental ingress of foreign bodies( food, food) into the respiratory tract.
This method consists of several techniques depending on the state of the person.
If the person is conscious and able to stand, the caretaker becomes behind the victim and wraps him around the abdomen with his hands at the level of the navel, clasping the hands in front in the "lock".Then you need to make a few strong squeezing movements. Thus, a sharp increase in intra-abdominal pressure is transmitted to the diaphragm and lungs. And the air in the lungs will push the barrier( foreign body) outwards and the victim will begin to breathe normally.
If the victim is unconscious, he should be laid with his back on a hard surface and pushed hard on the upper abdomen( at the stomach level).Children are more likely to get stuck in the respiratory tract than food, and toys and various items, so for more grown-up children, the Heimlich method is used, for the little ones - turning upside down and tapping on the chest from the back. If the child has a foreign body stuck in the throat, we must additionally press the index finger of the root of the tongue. Then, when tapping the chest in an inverted head, the foreign body will fall out.
What can not be done with asphyxia.
Leave the victim alone before the onset of a persistent recovery of consciousness or the arrival of a physician.
Give the affected person to eat or drink.
Knock the palm between your shoulders, as usual and do in the home. This can contribute to the fact that the foreign body will move along the airways even lower and cause a complete overlap of the large bronchus( trachea).And it can end even fatal in a few minutes.
Apply anything under the head, as this can cause constriction or blockage of the airways.
