The use of [[intravenous drip|intravenous fluids]] (IVs) may help compensate for lost fluid volume, but IV fluids cannot carry oxygen in the way that blood can, however [[blood substitutes]] are being developed which can. Infusion of [[colloid fluids|colloid]] or [[crystalloid fluid|crystalloid]] IV fluids will also dilute [[clotting factor]]s within the blood, increasing the risk of bleeding. It is current best practice to allow [[permissive hypotension]] in patients suffering from hypovolemic shock,<ref>http://www.trauma.org/archive/resus/permissivehypotension.html Permissive Hypotension</ref> both to ensure clotting factors are not overly diluted but also to stop blood pressure being artificially raised to a point where it "blows off" clots that have formed.

Excessive sweating is not a cause of hypovolemia, because the body eliminates significantly more water than sodium.<ref>http://highered.mcgraw-hill.com/sites/dl/free/0077262514/621682/Saladin_24_Ext_Outline.doc</ref> ==Diagnosis== Clinical symptoms may not be present until 10–20% of total whole-blood volume is lost. Hypovolemia can be recognized by [[tachycardia]], diminished blood pressure,<ref>http://www.stagesofshock.com/stage3/index.html</ref> and the absence of [[perfusion]] as assessed by skin signs (skin turning pale) and/or [[capillary refill]] on [[forehead]], [[lip]]s and [[nail beds]]. The patient may feel dizzy, faint, nauseated, or very thirsty. These signs are also characteristic of most types of [[Shock (circulatory)|shock]]. Note that in children, compensation can result in an artificially high blood pressure despite hypovolemia. Children will typically compensate (maintain blood pressure despite loss of blood volume) for a longer period than adults, but will deteriorate rapidly and severely once they do begin to decompensate. This is another reason (aside from initial lower blood volume) that even the possibility of [[internal bleeding]] in children should almost always be treated aggressively. Also look for obvious signs of external bleeding while remembering that people can bleed to death internally without any external blood loss. ("Blood on the floor, plus 4 more" = intrathoracic, intraperitoneal, retroperitoneal, pelvis/thigh) Also consider possible mechanisms of injury that may have caused internal bleeding such as ruptured or bruised internal organs. If trained to do so and the situation permits, conduct a [[Advanced_Trauma_Life_Support#Secondary_survey|secondary survey]] and check the chest and abdomen for pain, deformity, guarding, discoloration or swelling. Bleeding into the abdominal cavity can cause the classical bruising patterns of [[Grey Turner's sign]] or [[Cullen's sign]]. ===Stages of hypovolemic shock=== Usually referred to as "Class" of shock.
