It depends on the situation, pay attention to the contraindications of blood donation, patients with high blood pressure, low blood pressure, anemia, poor physical fitness, it is not suitable to donate blood, if there is an infectious disease can not donate blood, avoid infecting the infectious disease to others.

In the daily blood donation behavior, the general amount of blood donation is not more than 400ml, because the blood volume of the human body is related to the weight of the human body, the weight of the general blood accounts for 7%-8% of the human body weight, converted into volume, the normal blood of adults is about 4200-4500ml, and the blood donation of 400ml at a time basically reaches about 1 10 of the whole body blood volume, and the human body will not have obvious discomfort.

China advocates a donation of 200ml and 400ml of whole blood at a time, and the specific amount of blood donated will be considered according to the donor's weight, hemoglobin content and other health conditions.

At present, most countries in the world stipulate that each blood donation is 200ml 400ml, and European and American countries can donate 450ml and 480ml at a time, this standard is based on a large number of medical scientific research and nearly 100 years of global blood donation practice to prove, as long as blood donation conditions and blood donation precautions are donated blood will not cause any adverse effects on the human body.

Receiving one 400 ml bag of blood is theoretically twice as likely to cause a transfusion immune response and infectious disease as it is to receive two 200 ml bags of blood, so it is also more beneficial to the patient.

In fact, if you participate in the voluntary blood donation, as long as you donate once, you will basically have a free blood donation card, generally speaking, you can buy a donation of 200cc first, and there is no amount of blood required.

A healthy person's total blood volume accounts for about 8 percent of their body weight. Normally, 80% of the blood circulates through the heart and blood vessels; The other 20 percent of the blood is stored in organs such as the liver and spleen. In the event of blood loss or strenuous exercise, this blood enters the circulatory system.

The total blood volume of an adult is about 4000-5000 ml. Therefore, the weight standard for blood donation is set at 50 kg for men and 45 kg for women. A person who donates 200-400 ml of blood at a time, accounting for only 5-10 of the total blood volume, and the stored blood will be replenished immediately.

The water and inorganic substances lost after blood donation will be replenished in 1-2 hours; Plasma protein, which can be replenished within a day or two; Platelets, white blood cells and red blood cells also quickly return to their original levels.

The amount of blood in the human body is directly proportional to the body weight, generally accounting for 7% 8% of the body weight, such as a person weighing about 60 kg, the blood volume in the body is about 4200 4800ml. Therefore, people with heavier weight can consider donating a little more blood according to their own situation, which can be as high as 400ml. For those with a lower body weight, it is recommended to donate between 200 and 300ml.

Proper blood donation can promote the release of blood in the liver and spleen, promote blood metabolism, promote the bone marrow to make new blood cells, reduce the viscosity of blood, and avoid the formation of blood clots in blood vessels, thereby preventing cardiovascular and cerebrovascular diseases.
