Recently, accidents, plane crashes and other emergencies have become more frequent, because of which many people need a blood transfusion. Such blood can only be taken from donors, and now we’ll try to find out how much blood can be donated to such a person.
Is it helpful to donate blood?
In the human body, on average, there are about 5-6 liters of blood. Therefore, if you donate blood, following the recommendations of medical personnel, there will definitely be no harm from this. But the benefit will be both to the person who gets your blood and can survive, and to the donor himself. Therefore, before finding out how many liters of blood you can donate, let's figure out how good you will be with the delivery of such biomaterial.
- The circulatory system will be updated.
- The functioning of the liver will improve, one of the functions of which is the purification of blood from its dead particles.
- The immunity will increase and the digestive system will improve.
- The risk of developing cardiovascular disease will be reduced.
- Life expectancy will increase.
Contraindications to donation
As you can see, there are many advantages to donating blood. However, before you read further, in order to find out how much blood can be donated to a donor, it is better to determine if you have any contraindications to this, so that when you come to the donor center you will not be refused. So, you can not take biomaterial to persons:
- whose weight is less than 50 kg;
- whose age is less than 18 years;
- with a heartbeat of more than 55-100 beats per minute;
- with high or low blood pressure;
- suffering or having recently had a serious illness;
- those who have tattoos or treated their teeth in the last year;
- in contact with persons suffering from infectious or viral diseases;
- pregnant and lactating women, as well as women during menstruation and PMS.
Who can become a donor
Having found out to whom it is contraindicated to donate biomaterial, let’s clarify to whom it can be done, then to specify exactly how much blood can be donated at one time, and then go to the donor center. So, any person aged 18 to 60 years old with a weight of more than 50 kg who has undergone a medical examination, confirming that he is completely healthy and has no contraindications for such a procedure, can become a donor.
Moreover, sometimes even people over 60 are allowed to donate blood if they have not revealed any serious diseases, since, unfortunately, there are very few donors in our country, and the need for blood is quite high.
What you can’t do and what you need to do before donating blood
And now you have already outstripped that you have no contraindications to blood donation. How many times can I take it all the same? Does this question bother you? But this is understandable. However, let's first find out what you can’t do before you go to the donor center in order to avoid donating bad blood, which not only does not save the life of another person, but, on the contrary, can aggravate his situation.
- Two hours before the procedure, you can not smoke.
- Two days before blood donation, you can not drink alcohol.
- From the evening until the procedure, you should not eat fatty, spicy, smoked, and fried foods, as well as dairy products, eggs, bananas, chocolate and butter.
- Three days before the procedure, you should not take medications that have analgesics in their composition.
But instead, a day before going to the donor center, you should start drinking a lot of ordinary water, and in the morning on the day of blood donation you will definitely need to have a sweet oatmeal snack on water without oil or an ordinary bun with sweet tea.
Registration for blood donation
And then you finally came to the hospital to become a donor. However, before we know how much blood can be donated, let's first look at the process of registering and obtaining permission to donate. Actually, everything is very simple here.
First, you will need to go to the registry and fill out the "Donor Questionnaire" there, honestly answering all the questions. Then the potential donor is sent for a medical examination by a therapist who will measure his pulse and temperature, examine the mucous membrane and skin.
Be sure to take blood from a finger to determine the Rh factor and blood group, as well as the level of hemoglobin. After that, the transfusiologist analyzes all the available data, if necessary, asks additional questions, concludes whether a person can become a donor of blood or its components, and issues a referral to the buffet for tea with a bun.
How is the blood sampling process
Some potential donors are afraid to donate biomaterial only because they don’t know how blood donation is done, and they are afraid of this process. Therefore, before we tell you how many ml of blood can be donated to a person, let's figure out how it will look. First of all, you don’t need to worry that during the blood sampling an infection will be introduced into the body and infection will occur. This simply cannot be, because the whole procedure is performed by a disposable tool, which is unpacked right in front of the donor.
So, after unpacking the blood collection instrument, the donor sits in a comfortable special donor chair, a tourniquet is placed on his forearm so that the veins are visible, the area of the skin from which the blood will be taken is thoroughly disinfected. Only after this begins the process of sampling the biomaterial. The usual blood collection lasts about 5-10 minutes, plasma - 40 minutes, thrombocytapheresis - from half an hour to one and a half hours, erythrocytapheresis - 20-30 minutes.
How much blood can a man donate
So, let's now figure out the amount of biomaterial that a donor can donate in a specialized center. Usually this amount is 400 ml. However, if necessary, you can donate as much as 500 ml of whole blood.
In turn, the donor plasma can donate as much as 600 ml, red blood cells - up to 400 ml, and platelets - 200 * 10 9 cells. At the same time, a man can donate whole blood 5 times a year, no more than once every 60 days, and plasma - once a month, that is, at least up to 12 times a year.
How much blood can be donated to a female donor
Women recover much harder after blood donation, so they have a slightly different amount of biomaterial collected than men. And above all, this concerns the frequency of the procedure, since a woman can donate whole blood only 4 times a year, that is, no more often than once a quarter.
The only option when relaxation of these norms is allowed is an urgent need for this type of blood, but in this case, specialists will first conduct a thorough examination of the woman and decide how much she recovered from the previous collection of biomaterial. The volume of blood donated by women should average 370 ml, and should not exceed 450 ml.
Donation Recovery
Now that we have learned how much blood can be donated to a woman, and how much a man has completed this procedure, you need to let your body recover after taking the biomaterial. To do this, you must strictly follow the instructions of the doctors:
- 10-15 minutes you need to continue to lie in the donor chair, resting after the procedure and gaining strength;
- if you feel dizzy or nauseous, it is best to consult a doctor right away so that certain measures are taken to eliminate these symptoms;
- at least 2 hours after the procedure, do not smoke;
- 3-4 hours you can not touch and wet the bandage at the site of blood collection;
- during the day, any physical exertion should be avoided - this day should be spent in a relaxed mode;
- during the day it is not recommended to drink alcohol, with the exception of 100 grams of red wine;
- for two days, you should eat properly and regularly and drink more water to restore strength;
- within 10 days should not be vaccinated.
Legal benefits for a single blood donation
So, finally, we figured out how much blood can be donated and how much this biomaterial is donated on average, which means it's time to find out how the donor is compensated for his blood donation. After all, a person leaves work for this, suffers certain inconveniences, which means that the state is obliged to compensate for this.
Of course, blood donation itself is completely free and you should not go to this procedure just for the sake of receiving money. However, donating blood, you can get a free lunch at the clinic or cash compensation for it, the size of which is 500 rubles. In addition, for the donation of biomaterial, the donor receives a form 402 / y, which gives the right to 2 days of paid leave - on the day when he donates blood, and the next day.
In addition, if you donated your blood or its components several times a year, you can get a monetary reward from the state. To do this, before the beginning of April, you must provide your passport, application for monetary compensation in accordance with the established model, and received certificates from the blood transfusion center about the amount of biological material donated to the social protection authority located at your place of residence.
After that, within 95 days, the application is reviewed and the donor receives his monetary compensation. However, if no application is submitted before April, there will be no monetary reward for the previous year.
Honorary Donor
Now that we have learned in full detail about how much blood can be donated and how much donor will benefit from it, let's figure out how to get the title of “Honorary Donor of Russia” and what it will give you. So, in order to earn such an honorary title, you must necessarily donate your whole blood 40 times, 60 times - hardware plasma, and also more than 60 times - plasma, blood and its other components.
Having received such a worthy title, the honored donor can count on certain privileges:
- getting a vacation at any time at his convenience;
- getting vouchers to sanatoriums and rest homes in the first place;
- completely free travel both in public transport and in suburban;
- purchase of medicines at a significant discount;
- annual cash payments.
The last point is worth stopping separately. The amount of these payments, of course, is relatively small and amounts to about 12,000 rubles per year. However, due to inflation, changes in the cost of living and average wages are annually indexed for this monetary reward, due to which this amount can be further increased.
In addition, in certain regions of the country for people with the title of "Honorary Donor of Russia" additional privileges are legislatively fixed. For example, they may receive some compensation for the use of utilities and some more pleasant bonuses at the discretion of local authorities.
