Fatal time of arterial hemorrhage and first aid

Bleeding from a large artery usually kills in 5 minutes, and a small artery usually takes 10 minutes as in a hand.

First aid measures, hemostasis, blood transfusion.

Death from bleeding in the large arteries in 2-5 minutes.

First aid for traumatic bleeding.

Acupressure hemostasis, at the top of the wound, i.e., proximal end, find the beating blood vessels, and press tightly with your fingers This is an urgent temporary hemostasis method, and at the same time, materials should be prepared for other methods of hemostasis.

With this method, the rescuer must be familiar with the pressure points of vascular bleeding in each area.

Facial hemorrhage: Compress the facial artery between the mandibular angle and the mental tuberosity with the thumb.

Anterior head hemorrhage: compression of the temporal artery above the mandibular joint in front of the ear.

Posterior head hemorrhage: Compress the posterior auricular artery slightly below the posterior auricular protrusion.

Axillary and shoulder hemorrhage: In the supraclavicle concave, the outer edge of the sternocleidomastoid muscle is posteriorly down medially, aligning the first rib and pressing the subclavian artery.

Forearm hemorrhage: At the medial biceps biceps groove of the upper arm, pressure is applied to press the brachial artery against the humerus.

Bleeding in the palms and dorsum of the hands: Blood pressure in the beating radial artery is pressed within the wrist joint, where we usually press the pulse.

Finger bleeding: Use the finger on the unaffected side to pinch the root of the finger of the injured hand to stop the bleeding.

Thigh bleeding: Flex the thigh, relax the muscles, press the pressure point of the femoral artery with your thumb (at the midpoint of the groin at the base of the thigh), and press back forcefully, to increase the pressure, the thumb of the other hand can overlap the pressure.

Foot bleeding: On the underside of the ankle joint, where the dorsum of the foot beats, press tightly with your fingers.

Pressurized bandaging hemostasis: use sterilized gauze and cotton to make a cushion on the wound, and then bandage it vigorously to increase the pressure to achieve the purpose of hemostasis. This method is widely used and has good results.

You need to be rushed to the hospital for rescue.

Methods of hemostasis for arterial hemorrhage are:

1.Tourniquet first aid hemostasis: when the arteries of the limbs are bleeding, use a tourniquet to stop the bleeding.

It is best to stop the bleeding with a thicker, elastic rubber tube. If there is no rubber tube, you can also use a wide cloth belt for emergency needs. When using a tourniquet, first wrap a towel or bandage around the ** on the part above the wound, then stretch the rubber tube, tightly wrap it around the limb wrapped with the towel or bandage, and then tie the knot.

The tourniquet should not be wrapped too loosely or too tightly so that blood no longer flows. When the upper limb is injured, it is tied to the upper arm, and when the lower limb is injured, it is wrapped around the thigh to achieve the purpose of hemostasis. In principle, the time to tie the tourniquet should not exceed one hour, and if the tourniquet is needed for a longer time, the tourniquet should be loosened every half an hour for about half a minute.

While loosening the tourniquet, the wound should be pressed to avoid heavy bleeding.

2.Acupressure hemostasis: Use your thumb to press on the top of the bleeding blood vessel (proximal end) to close the blood vessel and interrupt blood flow. In areas where a tourniquet cannot be used, acupressure hemostasis may be used temporarily in an emergency.

3.Compression wound hemostasis: If the injury is serious and there is no hemostatic equipment nearby, you can use anything you can get at hand, such as a clean handkerchief, torn off clothing or directly press the wound with your hands to stop the bleeding, so as to buy time to send the wound to the hospital for treatment.

High intra-arterial blood pressure, high lateral pressure caused by blood flow to the blood vessel wall, and rapid blood flow Arterial bleeding, bright red in color, in the form of a jet; The intravenous blood pressure is low, the lateral pressure caused by the blood flow on the blood vessel wall is small, and the blood flow is slower Venous bleeding, dark red in color, slow outflow Therefore, arterial bleeding is more severe than venous bleeding When arterial bleeding is not stopped in time, the patient will die due to excessive blood loss

So the answer is:

Arteriole bleeding, the wound is not large, can be applied to the wound with sterilized cotton, pressure bandaging, usually can stop the bleeding.

If the bleeding does not stop, the injured limb can be elevated to slow the blood flow and help stop the bleeding.

When the bleeding of the limbs is severe, the tourniquet can be tied to the upper end of the wound, and a towel or cloth should be padded before the bandage, and then it has to be relaxed once every half an hour, and the binding time should not exceed 2 hours in total, so as to avoid ischemia and necrosis of the limbs.

After initial treatment, you should be sent to the hospital for treatment immediately.
