Features of blood flow by human body
Two atrium and two ventricles - these are four cavities of the human heart. From the vessels through the atrium blood enters the ventricles. Then the bloodstream leaves the right ventricle, heading through the vessels into the lungs, and is the so-called small circle blood circulation, And from the left ventricle, the blood enters the aorta, in all organs and fabrics, forming a large circle of blood circulation.
Within the framework of a small circle of blood circulation, natural gas exchange in the body is occur: blood is saturated with carbon dioxide, and herself takes away oxygen from there, when the red blood cells are associated with Hemoglobin. Great circle of blood circulation - sphere of reverse gas exchange and the area of focusing of nutritional trace elements. In the Blood aorta, the exchange products comes from tissues through the kidneys, skin and lungs.
It is not difficult to guess what happens if the blood circulation in the body suddenly stops: the gas exchange process and the useful substances will immediately stop. As a result, the exchange products will begin to accumulate in the cells, and carbon dioxide will overnight blood. Due to the stopped metabolism, the mass death of cells from intoxication and oxygen deficiency will occur.
Meaning of the procedure for resuscitation therapy
In most cases, make indirect, or closed, heart massage. Outdoor massage, when hand squeeze the heart directly, relevant with the opened chest cavity during operation.
Despite the fact that with a closed massage of the heart of direct access to the heart muscle, it is considered quite effective for the return of a person to life. The procedure is performed in such a way as to grind the heart with a sternum and a spinal column: under their pressure, the blood leaves the right ventricle and enters the pulmonary artery, and from there penetrates the blood circulation vessels. Ultimately, a full-fledged blood circulation is restored in the brain and coronary arteries, which causes independent rhythmic heart cuts. The indirect heart massage supports constant bloodstream before the heart is scored independently. The procedure is a wonderful way to restore your own electrical activity of the heart and normalize the work of the vascular heart.
When and who needs this procedure?
First you need to feel the pressing area. It is located at a distance of two fingers from the location of the Meso-shaped process in the center of the body axis vertically. Reanimating puts the base of the palms to the pressing area. The power of the junctions must be doubled due to the second palm and weight of their own body. Shone should be operational and rhythmic. Producing shocks on the sternum, remember that the optimal frequency of the impetus is one pressure per second. When performing shocks, the hand of the rescuer must remain straight in the elbows. The chest of the victim should be fed at 4-5 cm.
The purpose of these manipulations is to fill the heart of victim blood victim. To facilitate this process that makes a massage must tear off the arms from the sternum after each shock. At the same time, the legs of the injured person lifted by roller. MyMedinform.COM notes that the closed heart massage makes strictly along the vertical line, producing 101-112 jolts per minute.
Indirect heart massage for children
Features of this procedure, the child depends on its age.
Breast massage makes with the help of second and third fingers pads, children of teenage age - a brush of one hand. An adult man when stimulating a heart should be monitored so that the thumbs of his hand be directed to the head or foot of the victim, which depends on which side of the victim is resuscitative. When pressed, the fingers need to lift so that they do not touch the chest.
The technique of performing a closed massage of the heart in a small child is as follows: Breasts put back on a solid surface head to resuscator. Then pressed on its chest with two fingers, placing thumbs in front of the chest. Two other fingers are located under the blades of the baby.
Kids who have not yet turned 7 years old, a closed heart massage is convenient to make the bottom of the palm, while at the same time from the victim. At the newly recent infants, the infants of the chest should be about 1-1.5 cm, kids up to 1 year - 2-2.5 cm, in children over 1 year - approximately 4 cm.
Do not forget that the number of shocks in the sternum in 1 minute depends on the frequency of the child's pulse and its age. Based on this:
- newborns make 140 times per minute;
- Children 5-6 months - 130-135 pushes per minute;
- one year old kids - 125-130 times per minute;
- Two-year-old kids - 115-120 pushes per minute;
- three-year-old - 105-110 times per minute;
- four-year-100-105 jolts per minute;
- five-year-old - 100 times per minute;
- Six-year-90-95 jogs per minute;
- nine-year-old - 80-85 times per minute;
- twelve-year-old - 80 pushes per minute;
- Teenagers 13-16 years old - 75 times per minute.
During the completion of a closed massage of the heart, a person performing resuscitation can alternate two deep breaths (artificial ventilation of the lungs) with 15 shoes. This is a fairly effective measure to restore the normal vital life of the body of the victim. When performing this complex of rehabilitation, the condition of the victim is controlled by the pulse rate at the carotid artery, as well as by the fact that pupils react to bright light. Combine the procedure of indirect heart massage and Artificial respiratory Easy is convenient when resuscitation is carried out at once 2 rescuers. Their operational and coordinated actions before the arrival of doctors can save the victim.
How long do you need to perform the procedure
Stop providing first aid (abandon the indirect heart massage) in the case when the patient who is unconscious does not come to himself. As a rule, peripheral blood flow under the influence of a closed heart massage is normalized for a quarter of an hour. If, after the specified time, the normal pulsation of sleepy and peripheral arteries is not restored, the pupils are not narrowed, there are no breathing and knock of the heart, and the skin is distinguished by an unnatural light or a blue tint, massaging the heart in an indirect way is stopped.
