How Extreme Is Having To Put 7 Units Of Blood Into A Person

What would happen if someone lost 2 liters of blood?

First, 5 litres of blood is an estimate of how much blood an average 70kg man has – most patients are not 70kg men and their blood volumes vary accordingly. See: Estimated blood volume calculator.Second, the effects depend on the pre-blood loss hemoglobin concentration of the patient. If they are already anemic (low hemoglobin) much smaller volume blood loss may compromise tissue oxygenation. If they have high hemoglobin levels pre- blood loss they can lose much higher volumes before oxygenation is severely compromised.Third, this table shows what changes in vital signs would be expected with certain volume of blood loss. When circulatory volume starts dropping you body starts constricting arterioles leading to non vital organs, directing blood to vital organs such as your brain and heart. Your heart and respiratory increase to ensure oxygen delivery. Your body can compensate, up to a point. For example the blood pressure will not decrease until the patient has lost more than 30% of their blood volume.  I've seen an elderly person lose 1.7 litres of blood during routine operation. He did not require blood transfusion despite the blood loss.What then kills you if you have massive blood loss? When you lose enough blood, your body stops being able to compensate and goes into hypovolemic shock, your body is unable to maintain adequate perfusion to organs. In absence of adequate oxygenation your tissues start relying on anaerobic respiration, this leads to metabolic acidosis, which can result in cardiac (arrhythmia or cardiac arrest) or neurological (stupor, lethargy, seizures, coma) complications and dysfunction of organs which may be lethal. Acidosis also makes your blood less able to clot making it harder to stop the bleeding.Your heart rate can only increase so much to compensate for the reduced blood volume. After a point with faster rate your heart becomes less effective at pumping blood forward (eg. less time for the heart chamber to fill leads to lower stroke volume), this further compromises the oxygen delivery to vital tissues. In addition your heart muscle only receives oxygenated blood during diastole, when the heart is resting. When you lose blood you become tachycardic, your heart beats faster and faster and the myocardium receives less and less oxygenated blood and your heart may eventually stop because of lack of oxygen.

How do you determine someone's blood type fast in an emergency?

You don’t. You give O negative blood to everyone (some people/hospitals advocate using O positive blood for men and postmenopausal women and reserving O negative for premenopausal women to prevent formation of rhesus antibodies) until the blood is crossmatched.Generally if a trauma patient comes in, when inserting the cannulas the doctor takes blood samples and sends them to the lab for group and crossmatching.The initial resus fluid is 0.9% saline until you can get O negative blood. Depending on the availability of blood, the lab may send type-matched blood as the typing can be done in several minutes. Because typing can be done so quickly it is usually always done before sending type specific blood (unless the patient’s blood group has been tested in the hospital before so is already in their system) instead of relying on the patient/relative remembering it correctly as wrong blood can kill the patient.A full crossmatch takes about an hour and it tests the patient’s blood against the donor’s serum for antibodies.Crossmatch

What is the rarest blood type?

The most rare blood of world is AB(-). It's just add upto to be 5% population of world having this blood group..But from recent updates a new blood group INRA type is found which doesn't match with any other A, B, O, AB and also BombayBlood Groupor also called as HH Blood Group.As said a total of only 7 people are having this blood group in whole world.It's just said not a Proper confirmation is their till now.. that why till then AB(-) us the most rare one.Cheers!!

I donated blood and they gave me a wbn/din number?

Whether or not you are given an actual number, you are assigned one in the donation center's computer. The reason for this is because blood is classified as a drug, since it has a therapeutic effect upon administration to the body, so it is regulate by the FDA. Part of that regulation, and part of the standards of modern blood banking practice, is that you have to know the final disposition of each unit or component of blood your center has processed.

If a person tested positive for HIV on a donation, the testing center would contact them, and then each hospital or facility that got any component of that person's blood would be notified for a disposition check. Anyone who got components from the person who is now testing positive will have their doctor notified, and the doctor can decide whether or not to have them tested for HIV.

***Edit: I love how people give a thumbs down to valid information.

Would someone who is in a coma be put in a private room in hospital?

I'm doing research for a fictional story. What is the procedure for when someone who has been in a coma wakes up? Would that person be put in a hospital, or a hospice, or what? What machines would the person be hooked up to? Who are the first people he/she would see upon waking up out of the coma? Would that person be put in a private room in the hospital, or a normal ward, or what? How likely is it that someone in a coma will wake up? Is it dangerous for them to wake up? How long would it be till they could see their family? How long would it be till they can leave the hospital? Would they need to take any medication afterwords? Basically, I need to know everything you can tell me about what waking up from a coma is like. Note: this is a serious question. I expect to get serious answers from people who know what they are talking about. If you're arsing around, I'll know. I'm sorry to have to say that, but you know what people on the internet are like. I hope it doesn't offend you.

Had a blood sugar of 1147 ?

wensday I woke up very thirsty and urinating alot and thought nothing of it, thursday I went to work and lost my apetite and became thristy again, I felt fine except always going to the bathroom, Friday my vision began to blur and I was still thirsty and running to the bathroom, So I went home early from work, The next day my vision was totally screwed and very blurred, So I called into work that night and was going to take some tylenol pm (to help me sleep and I thought I had the flu) But my mom grabbed a bloodsugar machine from walgreens and tested me ( My grandmother had diabetis so she knew the symptoms) The machine said see doctor, So she rushed me to the hospital and right after they took another they rushed me into the emergency room and hooked me onto some IV thingy, I felt better and was not as thirsty but still my vision sucked, They also took a urine test, But I wanted to go home because I felt fine, Well the doctor came in and said I was going no were and my Blood sugar was 1147, My mom started crying and the doctor was puzzled that I was able to walk into the hospital and was still awake, But how can they know it was that high if there machines only go up to 600 ????


Im not over weight (140 pounds and 5/8) I have been in top health and get plenty of exercise?

people keeps telling me im lucky, But really can a blood sugar level that high kill you??? I felt nothing and if my vision was not messed up I would of never went to the hospital, Now im in insulin and I feel bad when it goes too low and it happens all the time, I think a low blood sugar can kill you because the first night out of the hospital the doctor put me on 25ml of lantus and I woke up in a sweat with a blood sugar level of 26 I think a low blood sugar can kill you more then a high one.
