Shock is known as an electrical discharge, emotional reaction and a harmful condition in the medical field. Thus, it is important to mention the stuffs which may threaten your life.
The way shock happens
There are several types of shock, but they have a characteristic in common that shock happens when not enough blood and oxygen can get to your organs. The closed system including blood vessels and capillaries have to be spread out adequate blood with pressure to push tiny little red blood vessels single file into the capillary beds. It can be said that shock is the result of insufficient of blood pressure.
Trouble with blood pressure
Several factor can make shock imminent, and shock normally leads to the low blood pressure. The stage when the shock continuously progress while the blood pressure is stable is called compensated shock. Until blood pressure turns to decrease, it moves to the stage of uncompensated shock which may be risk of dying if you are not administered in-time treatment.
The blood pressure can stabilize thanks to the cardiovascular system containing three different parts:
- Fluid (blood) that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products
- arteries and veins are tube-shaped vessels that carry blood in the body
- Heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries
Each the failure of the parts mentioned above can trigger four kinds of medical shock.
- Hypovolemic shock
Hypovolemic shock is a life-threatening condition that results when you lose more than 20 percent (one-fifth) of your body’s blood or fluid supply. This severe fluid loss makes it impossible for the heart to pump a sufficient amount of blood to your body. One of the prevalence cause of this shock is Dehydration which occurs when the amount of fluid intake is less than losing.
- Distributive shock
Distributive shock is triggered by blood vessels which open too much for the amount of fluid to keep the enough pressure although the amount of blood may be low or at the normal level.
Distributive shock usually begins from the vessels dilating as a result of a communication failure with the brain (neurogenic shock from a spinal cord injury, for example) or the histamines (anaphylactic shock).
- Cardiogenic shock
Cardiogenic shock stands in relation to the pump which is responsible for heart attacks and cardiogenic shock.
An example of cardiogenic shock is congestive heart failure in which heart work inefficiently. In this case, heart attack influences on one side of the heart, renders it cannot keep up with the speed of the undamaged site, affecting to blood pressure, causing a backup of blood into the body or into the lungs.
- Obstructive shock
A tension pneumothorax (also named a collapsed lung) is the most prevalence trigger of obstructive shock. In this case, air is trapped in the chest outside of the lungs. It interferes the heart pump enough blood and the squeezed vessels limit the amount of blood flow due to the pressure on the heart and vessels.
Besides, pericardial tamponade is also one of common cause of obstructive shock. Blood or fluids fill the space between the sac that encases the heart and the heart muscle. Aftermath, the blocked blood put pressure on the heart and curb the blood flow.
- Combinations of Shocks
There are some types of shock associating with more than two categories mentioned above. For instance, septic shock is the result of an infection, and causes drastic changes including not only dehydration but also vessel dilation in the body.
A chest injury, also known as chest trauma, is any form of physical injury to the chest including the ribs, heart and lungs. It may be a contributor to both a tension pneumothorax and serious bleeding such as hypovolemic.
Hypoperfusion is defined that the decreased blood flow through an organ. Although this shock is uncommon in medical field, but it help healthcare suppliers distinguish which types of shock.
