    How Much Blood Can Your Body Lose?

    Aug 15,  · You might still be alive, but your heart will be beating extremely fast. Smaller blood vessels will constrict, helping to keep blood pumping throughout your body. And after you lose over 50 percent of your blood or liters on average, then you’ll be in a comatose state. How much blood can you lose before you die? Once you hit the 50 percent mark, your body will not be able to cope with the low blood volume. If prompt medical treatment is not sought, your organs will begin to fail, as they will not be receiving the amount of oxygen and glucose required to sustain their functions, and the toxic waste products will not be removed efficiently.

    The sight of it causes anxiety, alarm, and sometimes even fainting. But without it, there would be no transport of how to use wall ties, regulation of temperature, or metabolism. This substance plays a key role in our immune system, and supplies the tissues of our body with the nutrients they need. Our bodies would be incapable of running without blood, since it is responsible for so how to get sour smell out of dishcloths of the things that make us functional.

    The reason the sight of it can cause so much distress, however, is because blood is supposed to stay inside of us — seeing blood means something is wrong.

    But what exactly happens when we start to lose blood? What happens when the fluid that is quite literally our life fo begins to flow out of us one way or another? Sometimes blood loss is so inconsequential we barely notice — a nick while shaving, the prick of a finger — but what about the times when blood loss is so great that our bodies begin to suffer serious consequences?

    Without blood properly performing its duties, we humans are in a fair bit of trouble. The technical word for blood loss is hemorrhage, which is defined as the escape of blood from the circulatory system through a ruptured blood vessel. Hemorrhaging can occur both inside internal bleeding and outside the body. Most of the time when we experience outer blood loss, we can take care of the damage pretty easily by ourselves.

    Some areas of the body, however, are more vulnerable than others to dangerous blood loss. Alton points to several blood vessels that could cause severe bleeding, including the jugular vein in the neck, the brachial artery in the armpit, and the many branches of the aorta located in the torso.

    The femoral artery may be king, though, when it comes to rapid blood loss. There are generally no symptoms of blood loss at this point, though some may feel slightly faint. A Class 2 hemorrhage is a loss of 15 to 30 how much blood loss to die of blood volume. This is where symptoms of blood loss begin to manifest. The next level of blood loss occurs with the Class 3 hemorrhage, which references loss of 30 to 40 percent of total blood volume.

    This could be around 3 to 4 pints of blood, for those keeping track. Blood transfusion is usually necessary with a hemorrhage of this magnitude, according to Alton. Smaller blood vessels are constricting to keep the body core circulation going.

    Vlood final classification of hemorrhaging, Class 4, occurs when a person loses over 40 percent of their blood volume. The heart will no longer be able to maintain blood pressure and circulation, Alton said, so organs will fail and the patient will slip into a comatose state preceding death. This hlood is called hypovolemic shockand the prognosis depends on many factors, including the amount of blood lost, the rate at which a patient is losing it, and the illness or injury underlying the blood loss.

    Though the dangers of severe bleeding are obvious, the body does have some defenses in place to try ohw survive. The reason we get so pale when losing blood is not simply because there is less blood in our body, but because of a process called vasoconstriction.

    Not unlike the survival response to large amounts of pressure acting on the body, bloov output is redistributed from less important areas of the body to the brain and torso. The body is trying to keep blood where it belongs, so it makes sense that our first-aid for hemorrhaging should follow the same model. Applying pressure with a sterile bandage or cloth and raising the injury above the level of the heart yow two good first steps in attempting to control bleeding.

    If all other methods have been exhausted, a tourniquet can be applied to the bleeding extremity. Using tourniquets, however, is controversial due to possibility of damaging tissue. For this reason, only those trained to use a tourniquet should attempt to apply one.

    Drawing Blood

    The typical adult has about 5 litres of blood. You can lose 10% without problems - that's a typical blood donation. On the other hand 40% (2 litres) of rapid loss would be expected to cause death in an otherwise healthy individual although the same amount over a few days could be compensated for.

    Blood loss is definitely not a pleasant experience, and, for whatever reason someone might be losing blood — an accident or a disease, such as hemophilia — the aspect of becoming anemic or even dying can be very unnerving. The more common causes of blood loss, such as getting blood tests done, menstruation and nose bleeds, typically do not cause complications; however, roadside accidents, surgeries, etc.

    In this article, we will address the question: How much blood can you lose before you die? The question we first need to address is whether there is a universally accepted threshold of the volume of blood that can be lost before death occurs.

    The answer is no. The amount of blood you can lose before you face complications varies based on your physique, age, and health condition. Thinking in terms of the proportion of blood lost is a better approach. For example, adult men in general have a higher volume of blood in their bodies, so they can afford to lose more blood than adult women. Children, however, have a smaller volume of blood , so a seemingly minor amount of blood loss can affect them adversely. Generally, adults can afford to lose approximately 14 percent of their blood without sustaining damage to their vital organs or facing major side effects; however, dizziness and lightheadedness might occur if the blood is lost too rapidly.

    If you have lost between 15 and 30 percent of your blood, your body will begin responding with palpitations, rapid breathing, decreased urine output, decreased blood pressure and anxiety. In addition, vasoconstriction — decrease in the diameter of the vessels — will occur in your arms, legs and extremities so that the blood pressure in your vitals can be maintained.

    Since the blood flow to your skin will be reduced, you might start looking pale and your skin might feel cool to the touch.

    The body perceives this as a major trauma. As blood flow to your brain decreases, you might begin to experience a brain fog and disorientation. As blood loss increases, the decreased blood pressure would mean that your body cells are not receiving enough oxygen and glucose for respiration; consequently, you might pass out.

    At this point, urgent medical attention is needed to avoid more complications and more blood loss. If you lose about 20 percent of your total blood volume, your body will start going into hypovolemic or hemorrhagic shock.

    The intensity of these symptoms increases with increased blood loss. Some of the symptoms of a hypovolemic shock are:. If the volume of blood lost crosses 40 percent of your total blood volume , the protective mechanisms of your body fail and it becomes difficult for your heart to maintain circulation to your vital organs. Serious damage begins to occur to your organs, and your body might even go into a coma. Once you hit the 50 percent mark , your body will not be able to cope with the low blood volume.

    If prompt medical treatment is not sought, your organs will begin to fail, as they will not be receiving the amount of oxygen and glucose required to sustain their functions, and the toxic waste products will not be removed efficiently. Before your body moves into a coma, you will experience extreme fatigue, but when nearing death, these feelings will become unnoticeable.

    Although your body has great coping mechanisms, it can only handle blood loss up to a certain level. Your organs will begin to stop functioning, as your body will stop supplying blood to all organs it deems unnecessary for survival; eventually, your heart will stop pumping blood and your body will move from a state of coma to death if aggressive end-of-life treatments such as resuscitation are not sought.

    The usual parameter used to decide if a transfusion is necessary is blood hemoglobin level. Men typically have a hemoglobin level between Your doctor will take various factors into consideration before administering a transfusion.

    For blood loss greater than 40 percent of the blood volume , especially in the case of poorly controlled bleeding, a transfusion may not be as effective and the symptoms may become more difficult to reverse. You doctor will consider your overall health, your rate and site of injury, as well as additional injuries before deciding whether or not to administer a transfusion. Blood loss can occur in a variety of situations; you may not even feel the effect of minor blood loss such as that from a small cut.

    Adults can lose quite a bit of blood without any major consequences. Here are some common situations in which you can lose blood, and the consequences of blood loss in these cases.

    You will typically donate one of the ten pints of blood in your body, i. This will not usually cause any major consequences. Although nosebleeds are definitely bloodcurdling, you do not actually lose as much blood as it might seem — not enough to cause major side effects. However, if your nosebleed is very heavy and you have soaked several tissue papers within a span of 5 minutes, it would be advisable to seek medical attention.

    Although seeing blood on your underwear or toilet paper can be daunting, it is rarely a cause of concern, at least in terms of blood loss. You will usually lose only a small amount of blood from a bleeding hemorrhoid. Depending on how heavy your period is, you will usually lose between 60 and 80 mL of blood in one cycle. If you believe that your bleeding is exceptionally heavy, see a doctor; telling them how quickly you go through pads or tampons will help them determine the degree of blood loss and whether it needs medical attention.

    Although bleeding during a miscarriage early on during your pregnancy is similar to that during your period, the bleeding can be heavy later during your pregnancy. The onset of this bleeding is often sudden and you might bleed profusely. Bleeding may also be accompanied by contractions and back ache.

    Natural childbirth leads to a loss of approximately mL — half a quart — of blood, while a cesarean delivery leads to a loss of 1 liter of blood on average. In the case of complications, more blood loss can occur, but your doctor will do their best to manage your bleeding and ensure that you are not in danger. Lab tests are nothing to worry about when it comes to blood loss. Your doctor will only draw about 8.

    Although your surgeon will make every effort to minimize blood loss, you might still end up losing a significant amount of blood during a surgery, especially in the case of a complication. Your doctor will discuss the possible blood loss during the surgery with you beforehand, as well as the steps that would need to be taken if you end up losing too much blood. Your body does have coping mechanisms in place to counter the effects of blood loss, but the rate and amount of loss can greatly affect the consequence of blood loss.

    During an injury, for example, you can lose a significant amount of blood in a short amount of time — in such cases, prompt medical care is necessary. Slower bleeding can be more difficult to assess as needing medical attention. Internal bleeding should not be overlooked; if you suspect internal bleeding, seek medical attention.

    Whether the amount of blood you have lost is sufficient to cause major complications, even death, or not, depends on the proportion of your blood lost, not the volume.
