How to Provide First Aid for Bleeding

To begin with, visually determine the type of bleeding: arterial, venous, or capillary. Erste-Hilfe Kurs München teaches that any of them are potentially life-threatening.

Arterial bleeding case

Arterial bleeding occurs when arteries are damaged (large pulsating tubes of various diameters, through which blood passes from the heart to organs and tissues under high pressure), the most dangerous.

Brk sanitätsdienst provides the signs: scarlet blood gushes from the wound with a strong pulsating stream.
First aid: press a bleeding vessel with your fingers or apply a tourniquet (above the wound site, since the direction of blood flow is from the center to the periphery.
When this time has elapsed and you move the tourniquet, apply finger pressure in the wound or throughout.

Give the bleeding area an elevated position, apply a clean pressure bandage, bend the limb at the joint as much as possible. Press the vessels above the wound at certain anatomical points to find where the vessel passes superficially. Malteser sanitätsdienst considers it better to press not with one, but with several fingers of one or both hands, lined up in one line.

A tourniquet is applied when large arteries of the extremities are damaged above the wound so that it completely squeezes the artery.
A tourniquet is applied with a raised limb, placing a soft cloth under it (bandage, clothing, etc.), making several turns until the bleeding stops completely.
The turns should lie close to one another so that folds of clothing do not fall between them. The ends of the tourniquet are securely fixed.

Asb sanitätsdienst advises attaching a note to the tourniquet indicating the time the tourniquet was applied. The tourniquet is applied in summer for no more than 1.5 hours, in winter for 40 minutes. You can not hide the imposed tourniquet under clothes.
