Progressive Shock. Low Cardiac Output decreases arterial pressure and reduces transport of nutrients to tissues Blood pH then decreases because of lactic & carbonic acid buildup.
Some texts refer to Dehydration as “a form of shock”, however the terms are not synonymous.
Dehydration is the result of total body water loss
Hypovolemic shock results from loss of blood volume and MAY result from dehydration as well as other alternate or contributing factors.
Forms of Shock:
Fluid Loss is primarily from Vascular spaces:
Sweat glands move fluid from the blood to the skin
Kidneys move fluid from the blood to the urine (highest contributor to fluid loss)
Fluid may also be lost through breathing as well as vomiting or diarrhea (lost fluid originally from blood within gut walls).
This fluid loss may CAUSE hypovolemic shock.
