Traumatic wounds and hemorrhages are some of the most common injuries that we have to deal with in traffic accidents. Massive hemorrhages are deadly for us. An uncontrolled hemorrhage leads to shock, called hypovolemic shock, and death. How to effectively help a victim with massive hemorrhages? You will learn about this at erste hilfe kurs ohne anmeldung.
Causes of bleeding
The most common cause of hemorrhage is injuries. When you are injured as a result of an injury, for example, you break the skin and damage a large vessel through which blood is transported. We are talking then about external hemorrhage. It is a situation where blood from a damaged vessel “escapes” through a wound, through the damaged skin, and outside our body.
Internal bleeding is the opposite. For example, blood from a damaged vessel is poured into your body. Mixed hemorrhage is a situation where there is blood in your body, i.e. internal hemorrhage, and blood released through natural openings in your body – e.g. nose, mouth, etc. The erste hilfe kurs instructor must tell you about the causes of bleeding.
Deadly hemorrhagic shock
A shock is a life-threatening form of acute heart failure associated with insufficient oxygen consumption by the cells. It is a condition in which the circulatory system does not supply the tissues (and vital organs) with oxygen and nutrients in the amount needed. In hypovolemic shock, there is a reduction in total blood volume, i.e. whole blood loss due to internal or external hemorrhage. We then call it hemorrhagic shock. Serious problems begin with a loss of 20-25% of circulating blood!
Venous and arterial hemorrhage
In erste hilfe kurs für führerschein, this topic is given some attention. Arterial blood is saturated with oxygen, so it is light red. Venous hemorrhage is slightly calmer and milder. It is softer in the sense that it is not so violent but more uniform.
