Compensated Shock

Compensated shock, blood pressure decreases only a moderate amount, and the mechanisms that regulate blood pressure successfully reestablish normal blood pressure and blood flow. As blood volume decreases, the stress-relaxation response of blood vessels causes them to contract and helps sustain blood pressure. Progressive shock, blood pressure declines to a level that is inadequate for maintaining blood flow to cardiac muscle. When blood pressure declines to a very low level, blood begins to clot in the small vessels and blood vessels begin to dilate due to decreased sympathetic activity and a lack of oxygen in capillary beds. Capillary permeability increases under ischemic conditions, allowing fluid to leave the blood vessels and enter the interstitial spaces. Shock leads to irreversible shock in this stage, the damage to tissues, including cardiac muscle. Irreversible shock is decreasing heart function and progressive dilation of and increased permeability of peripheral blood vessels. Patients suffering from circulatory shock are normally placed in a horizontal position, usually with the head slightly lower than the feet. Oxygen is often supplied. Several types of shock can be classified by cause.

• Plasma loss shock is causes of plasma loss shock include intestinal obstruction, in which a large amount of plasma moves from the blood into the intestines and severe burns, which cause large amounts of plasma to be lost from the burned surface.
• Neurogenic shock is a rapid loss of vaso-motor tone, leading to vasodilation so extensive that blood pressure declines severely.
• Emotional shock stems from emotions that cause strong parasympathetic stimulation of the heart and results in vasodilation in skeletal muscles and in the viscera.
• Anaphylactic shock results from an allergic response in which the release of inflammatory substances increases vasodilation and capillary
