First aid for bleeding

Fundamentals of First Aid (OPMP)

At the first sign bleeding steps should be taken to stop it. Various physical, biological and medicinal means are used. With external bleeding, a temporary (preliminary) and permanent (final) stop of bleeding is distinguished. Temporary stop of bleeding prevents dangerous blood loss and allows you to buy time for the final stop of bleeding. Ways to temporarily stop external bleeding include:

1) applying a pressure bandage; digital pressure of the artery;

2) application of a hemostatic tourniquet; forced flexion of the limb.

A pressure bandage to temporarily stop external bleeding is applied mainly for small bleeding (venous, capillary) and for bleeding from small arteries. The imposition of a pressure bandage is the only method for temporarily stopping bleeding from wounds located on the trunk, on the scalp

Pressing the artery along, i.e., not in the area of the wound, but higher (closer to the heart in the blood flow) is the most accessible way in any situation to temporarily stop large arterial bleeding. To use it, you need to know the place (point) where this artery lies closest to the surface, and it can be pressed against the bone; at these points, you can almost always feel the pulsation of the artery. Finger pressure makes it possible to stop bleeding almost instantly. This technique is important because it allows you to buy time for other methods of temporarily stopping bleeding, most often for applying a tourniquet.

Tourniquet application is the main way to temporarily stop bleeding in case of damage to large arterial vessels of the extremities. With the correct application of the tourniquet, the bleeding immediately stops, and the skin of the limb turns pale. The degree of compression is determined by the pulse on any available artery below the applied tourniquet. A note should be attached to the tourniquet indicating the time of its application, since after 2 hours from the moment of application, the tourniquet should be removed, otherwise congestion will develop in the tissues of the limb, leading to necrosis.

Forced limb flexion as a way to temporarily stop bleeding is applicable to the upper limb. With forced flexion of the limb, bleeding stops due to the bending of the arteries.

With any bleeding, and especially the limbs, it is necessary to give an elevated position and ensure the rest of the affected part of the body. The final stop of external bleeding is carried out by the surgeon, to whom the victim must be immediately delivered.

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. ... >>

Wireless charging for Toyota electric vehicles 11.12.2013

Toyota Motor Corporation has entered into an agreement with WiTricity Corporation, a manufacturer of induction chargers. The peculiarity of WiTricity's business model is that it does not sell finished products, but licenses for their development. Through the collaboration, Toyota will gain access to WiTricity Corporation technologies. The ultimate goal is to equip both all-electric and hybrid Toyota vehicles with wireless battery charging systems.

Chargers based on WiTricity patents use the classic effect of electromagnetic induction, which involves the interaction of two coils with current. In this case, one of the coils is built into the transmitter connected to the electrical network (it can lie, for example, on the garage floor), and the second coil is located inside the car. The battery starts charging automatically when the car is parked over the transmitter.

With regard to passenger cars, the technology allows charging an "empty" battery in 4 hours, while transferring from 3,3 to 6 kW of energy. This figure can reach 25 kW for larger vehicles. The developers report that wireless charging takes about the same time as conventional charging from the mains.

To date, it has not been specified in which Toyota car models WiTricity technology will be used. In August 2013, the Japanese automaker announced plans to add wireless charging capabilities to its green Prius line. At that time, it was about the 2014 Toyota Prius Plug-In model.

There are more than 2445 CHAdeMO express charging stations globally today, roughly double the number from a year earlier, according to analysts at IHS Automotive. CHAdeMO technology is supported by more than 57 electric vehicles (including Mitsubishi i-MiEv, Nissan Leaf and Honda Fit EV models), accounting for about 80% of the non-ICE vehicle market.

The cost of installing one CHAdeMO charging station is in the range of 20-30 thousand dollars. Such a station makes it possible to charge the batteries in about 20 minutes, although, of course, this is still much longer when compared with the time of refueling gasoline at a conventional gas station.

Tesla Motors is working on a faster "recharge" method. The company equips its vehicles with rechargeable batteries that can be replaced after being discharged at specialized stations. This battery replacement takes only 10 minutes.
