What is Hypovolemic Shock?
According to the University of Maryland Medical Center, Hypovolemic shock is an emergency condition in which severe blood and fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working. Losing about 1/5 or more of the normal amount of blood in your body causes hypovolemic shock. The signs and symptoms of hypovolemia include:

• Cold skin
• Agitation and anxiety
• Decrease in the output of urine
• Confusion
• Feeling of weakness in general
• Paleness in skin
• Rapidness in breathing
• Moist skin and increased sweating
• Falling unconscious
Hypovolemic shock can result in orthostatic hypotension, which means there can be lowered blood pressure. The person feels dizzy and might even lose consciousness. Hypovolemia can hinder the amount of blood that the heart pumps to the organs. This indicates that there are many signs related to the heart caused by hypovolemia. One of the major signs is tachycardia, which is characterized by the rapid beating of the heart. The skin loses its elasticity and inability to be stretched as compared to normal. This is the result of loss of fluid from the body and reduction in the blood volume. The temperature of the body is regulated by different factors; any change in the loss of fluid, intake of fluid or alteration in perspiration can result in rise or fall of body temperature. Another sign of hypovolemia can be increase in the body temperature.

For adults, the clinical staging relating to loss of blood volume can be classified as: * Class 1: 10 to15% blood loss; physiological compensation, only minimal tachycardia is seen. Usually, no changes in BP, pulse pressure, or respiratory rate occur. A delay in capillary refill of longer than 3 seconds corresponds to a volume loss of approximately 10%. * Class 2: 15 to 30% blood loss; postural hypotension, generalised vasoconstriction and reduction in...
