What Is Hypovolemic Shock?

Hypovolemic shock is a life-threatening condition that results when you lose more than 20 percent (one-fifth) of your body's blood or fluid supply. This severe fluid loss makes it impossible for the heart to pump a sufficient amount of blood to your body. This condition requires immediate emergency medical attention because it can lead to organ failure.

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. Blood transfusion is usually necessary with a hemorrhage of this magnitude, according to Alton.

Hypovolemic shock results from significant and sudden blood or fluid losses within your body. Blood loss of this magnitude can occur because of:

– bleeding from serious cuts or wounds
– bleeding from blunt traumatic injuries due to accidents
– internal bleeding from abdominal organs or ruptured ectopic pregnancy
– bleeding from the digestive tract
– significant vaginal bleeding
– Endometriosis

In addition to actual blood loss, the loss of body fluids can cause a decrease in blood volume. This can occur in cases of:

– excessive or prolonged diarrhea
– severe burns
– protracted and excessive vomiting
– excessive sweating

Blood carries oxygen and other essential substances to your organs and tissues. When heavy bleeding occurs, there is not enough blood in circulation for the heart to be an effective pump. Once your body loses these substances faster than it can replace them, organs in your body begin to shut down and the symptoms of shock occur. Blood pressure plummets, which can be life-threatening.

The symptoms of hypovolemic shock vary with the severity of the fluid or blood loss. However, all symptoms of shock are life-threatening and need emergency medical treatment. Internal bleeding symptoms may be hard to recognize until the symptoms of shock appear, but external bleeding will be visible. Symptoms of hemorrhagic shock may not appear immediately. Older adults may not experience these symptoms until the shock progresses significantly. Some symptoms are more urgent than others.

Mild symptoms can include:

– headache
– fatigue
– nausea
– profuse sweating
– dizziness

Severe symptoms, which must be taken seriously and warrant emergency medical attention, include:

– cold or clammy skin
– pale skin
– rapid, shallow breathing
– rapid heart rate
– little or no urine output
– confusion
– weakness
– weak pulse
– blue lips and fingernails
– lightheadedness
– loss of consciousness

The sign of external hemorrhaging is visible, profuse bleeding from a body site or area of injury.

Signs and symptoms of internal hemorrhaging include:

– abdominal pain
– blood in the stool
– black, tarry stool (melena)
– blood in the urine
– vomiting blood
– chest pain
– abdominal swelling

Emergency care and first aid

Untreated hypovolemic shock will lead to death. Hypovolemic shock is a medical emergency. Call 911 immediately if you observe a person experiencing shock symptoms. Until responders arrive:

- Have the person lie flat with their feet elevated about 12 inches.
- Refrain from moving the person if you suspect a head, neck, or back injury.
- Keep the person warm to avoid hypothermia.
- Don't give the person fluids by mouth.
- Don't elevate their head.
- Remove any visible dirt or debris from the injury site. Do not remove embedded glass, a knife, stick, arrow, or any other object stuck in the wound. If the area is clear of debris and no visible object protrudes from it, tie fabric, such as a shirt, towel, or blanket, around the site of injury to minimize blood loss. Apply pressure to the area. If you can, tie or tape the fabric to the injury.

What complications are associated with hypovolemic shock?

A lack of blood and fluid in your body can lead to the following complications:

- damage to organs such as your kidney or brain
- gangrene of the arms or legs
- heart attack

The effects of hypovolemic shock depend on the speed at which you're losing blood or fluids and the amount of blood or fluids you are losing. The extent of your injuries can also determine your chances for survival. Chronic medical conditions such as diabetes, previous stroke, heart, lung, or kidney disease, or taking blood thinners like Coumadin or aspirin can increase the likelihood that you'll experience more complications from hypovolemic shock.

How long does it take for someone to pass out due to blood loss?

You can lose quite a bit of blood without experiencing any side effects or complications. The exact amount depends on your size, age, and general health.

It helps to think of loss in percentages instead of total amounts. Adult men, on average, have more blood than most adult women. This means they can typically lose a little more before experiencing adverse effects. Children, on the other hand, have much less blood than adults, so even small blood losses could affect a child negatively.

Most adults can lose up to 14 percent of their blood without experiencing any major side effects or changes in vital signs. Some, however, may feel lightheaded or dizzy if this amount is lost quickly.

How much blood can you lose before you begin to experience mild side effects?

You'll start to feel mild side effects, such as nausea, when blood loss reaches 15 to 30 percent of total blood volume. This amount of loss increases your heart and respiratory rates. Your urine output and blood pressure will be decreased. You may feel anxious or uneasy.

Your body starts to compensate for blood loss by constricting the blood vessels in your limbs and extremities. This is your body's attempt to maintain your blood pressure and blood flow. This subsequently lowers the amount of blood your heart pumps outside the center of your body. Your skin may become cooler and pale.
