Erste-Hilfe Kurs München informs that stopping bleeding is a measure aimed at stopping blood loss. When giving first aid, we are talking about stopping external bleeding. Depending on the type of vessel, a distinction is made between capillary, venous, and arterial bleeding.
For venous bleeding, a pressure dressing is applied. This is done by tamponade of the wound: gauze is placed on the wound, over it several layers of absorbent cotton (if no wool – clean towel), tightly bandaged. Veins compressed by such a dressing quickly thrombose and bleeding stops. If the bandage gets wet, press it hard with the palm of your hand.
To stop arterial bleeding, the artery must be clamped.
Technique for clamping the artery: press the artery firmly with your fingers or fist against the underlying bony formations.
Erste Hilfe ostbahnhof says that arteries are easily accessible to palpation, so this technique is very effective. However, it requires physical strength on the part of the first aid provider.
If the bleeding does not stop after applying a tight bandage and compressing the artery, apply a tourniquet. Remember, this is the last resort when other methods do not work.
Techniques for applying a tourniquet
At Erste Hilfe münchen they teach to apply tourniquet in 4 steps:
- Place the tourniquet on clothing or soft padding just above the wound.
- Tighten the tourniquet and check the pulsation of the vessels: the bleeding should stop and the skin below the tourniquet should be pale.
- Apply a dressing to the wound.
- Record the exact time the tourniquet was applied.
A tourniquet can be applied to a limb for a maximum of 1 hour. After that time, the tourniquet should be loosened for 10-15 minutes. If necessary, the tourniquet can be tightened again, but not for more than 20 minutes.
