RџSЂRё artificial respiration in the mouth-to-mouth method, the caregiver draws as much air into the lungs as possible and exhales vigorously into the lungs of the victim through his mouth or nose. Exhaled air contains more than 16% oxygen, and the volume of air entering in this case into the lungs of the victim is about four times greater than with other methods of artificial respiration. At the same time, the pulmonary alveoli actively expand and reflex excitation of the respiratory center of the brain occurs, which determines the effectiveness of the use of such artificial respiration, not accidentally called the "kiss of life" (Fig. 76).

Rice. 76. Performing artificial respiration according to the "mouth to mouth" method.

Before starting artificial respiration, it is necessary to make sure that the upper respiratory tract of the victim is free for the passage of air.

If it is not possible to open the mouth, one should carefully insert any board, metal plate, spoon handle, etc. into the corner of the mouth between the molars and unclench the teeth. Then it is necessary to remove liquid and mucus from the oral cavity (if they have accumulated) using a handkerchief or any other soft tissue, if there are removable teeth or dentures, they must be removed. Only after this, the victim is placed on his back, the assisting person kneels at the head of the victim from any side. One hand should be placed under the neck of the victim, and with the other hand, tilt his head back as much as possible. Then it is necessary to pinch the nostrils (to exclude the possibility of the exit of the blown air through the nose) with the thumb and forefinger of the hand with which the head was thrown back. In this position, the assisting person takes a deep breath and, pressing his mouth tightly (through a handkerchief or gauze) to the victim’s open mouth, blows air sharply and strongly for 5 seconds so that the victim’s chest rises noticeably. After this, it is necessary to move away from the victim so as not to interfere with the free exit of air from the lungs.

It is better to blow air through special rubber tubes produced by the industry. One end of the tube, up to the oval flange on it, is inserted into the victim's mouth so that it enters the windpipe, and not the esophagus.

At the end of the exhalation, the assisting person takes a deep breath and the whole cycle repeats. Such injections should be done at least 12-15 per minute (in the rhythm of one's own breathing).

If the victim's jaws are tightly clenched and cannot be quickly unclenched, it is necessary to blow air into the victim's nose. When helping young children, air is blown into the mouth and nose simultaneously. The frequency of injections in this case should be 15-18 per minute. The volume of air blown in decreases according to the age of the child.

If the victim began to breathe on his own, then artificial respiration should be continued for some time, blowing in air at the same time as the victim begins to inhale. The pulse is best checked at the neck by pressing two fingers (thumb and forefinger) against the arteries on both sides of the neck. In addition to artificial respiration, it is necessary to do heart massage in parallel.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
