Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [ 1 ] [ 2 ] It can be caused by severe dehydration or blood loss . [ 3 ] [ 2 ] Hypovolemic shock is a medical emergency ; if left untreated, the insufficient blood flow can cause damage to organs , leading to ...
The 4 stages are sometimes known as the "Tennis" staging of hypovolemic shock, as the stages of blood loss (under 15% of volume, 15–30% of volume, 30–40% of volume and above 40% of volume) mimic the scores in a game of tennis: 15, 15–30, 30–40 and 40. [20] It is basically the same as used in classifying bleeding by blood loss. [citation ...
Shock is when the body does not have adequate circulation to provide oxygen to body tissues. Hypovolemic shock occurs due to low circulating volume of fluids in the blood vessels. Distributive shock , which can occur due to anaphylaxis or sepsis, results in widespread dilation of blood vessels in the body resulting in lower blood pressure.
Shock is divided into four main types based on the underlying cause: hypovolemic, cardiogenic, obstructive, and distributive shock. [2] Hypovolemic shock, also known as low volume shock, may be from bleeding, diarrhea, or vomiting. [1] Cardiogenic shock may be due to a heart attack or cardiac contusion. [1]
Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination . [ 2 ]
The first category is called hypovolemic shock. Hypo- means “low”, -vol- refers to “volume”, and -emia refers to the blood, so hypovolemic shock is shock induced by a low fluid volume of blood, and this could be either non-hemorrhagic or haemorrhagic.

A common type of surgical shock is hypovolemic shock, which is often caused by blood loss. [1] [2] Other types of shock include cardiogenic, obstructive and distributive. [3] [4] Failure to identify and treat the underlying cause of shock in any setting may lead to irreversible multiple organ damage, organ failure, and death. [2] [4] [1]
