Why we should donate blood?

We are often able to answer questions:
– Why donate blood?
– How come there’s no blood?
– Isn’t the state concerned?
It is understandable that such questions are posed because of the lack of information on blood donation and the role of blood in the treatment of sick and injured people.
Blood is a liquid tissue that flows in a closed circulatory system. Blood is a hereditary and unchanging characteristic of humans. We already know that there are 4 blood groups: A, B, O and AB. An adult human body contains 5 to 6 liters of blood (depends on the person’s height and weight). The basic function of the blood is to supply oxygen and nutrients to the tissues, and to remove carbon dioxide. The bone marrow produces new and fresh blood cells, whose life span is 120 days, which means that the blood is restored.
Blood consists of erythrocytes, platelets, leukocytes, and plasma (the liquid part of the blood). Each of these elements plays an essential role in our body. Due to illness, injuries, traffic accidents and the like, the bone marrow is not able to produce enough blood. Then a blood transfusion is required. That is why it is said to be blood-medicine.
We never know when a person will need blood. Therefore, the blood should always “wait” for the patient and not vice versa. The only source of this medicine is the blood donor. When they find themselves in one of these situations, all people are dependent solely on blood donors. The blood we donate is a precious drug that depends on the lives of many patients. We are all responsible for sufficient amounts of blood because it depends on us whether there will be sufficient blood supply.
A single dose of blood can save three lives
The usual dose to be given is 450 ml of blood. This is the standard dose of blood taken. According to it, the required number of doses of blood products for the treatment of the patient is calculated. Giving whole blood takes 8-12 minutes. From a dose of 450 ml of blood, one dose of erythrocyte concentrate, one dose of platelet concentrate and one dose of plasma are processed.
Any healthy adult age 18-65 can be a blood donor. A medical examination checks the level of hemoglobin in the blood and determines that donating blood will not endanger the person who donates the blood or the person to whom it would be given blood.

For blood donation, the following criteria must be met:
-that the person is healthy and in good overall condition
-weight of 50 kg
-Hemoglobin should be above 135g / L (Hct = 0.38) for men
-Hemoglobin should be above 125g / L (Hct = 0.4) for women
-the interval between blood donation is 3 months (for men) and 4 months (for women)
The medical technician will determine the hemoglobin level and your blood type from a drop of your blood. The hemoglobin is determined by a medical examination. Your doctor measures your blood pressure and takes a medical history and gives you an assessment of whether you can be a blood donor. After a medical examination, you begin to donate blood for 8-12 minutes. The accessories used for taking blood (needles, PVC systems, PVC bags, etc.) are sterile and disposable. There is no possibility of infection. All donated blood is tested for hepatitis B and C, HIV and syphilis. If any of these tests are positive, you will be notified. You should be honest with every medical examination. Tell your doctor even your doubts as this protects yourself and other patients.
Becoming a blood donor is a privilege that contains responsibility to yourself and the patient. Blood donation is free, anonymous and voluntary.
Blood transfusion saves patients every day. In hospitals, donated blood is given to injured and sick people.
In all countries of the world there is a constant need for blood donors and for meeting the needs with blood components. The role of healthy and sick persons is to encourage blood donation.
