Circulatory Shock Overview

A state where blood flow is insufficient to deliver oxygen and nutrients to tissues, leading to potential cell damage.

Circulatory shock caused by a loss of blood volume. This can be due to blood loss (hemorrhage), plasma loss, or both.

Hypovolemic shock due to bleeding.

Hypovolemic shock caused by loss of plasma from the bloodstream, even without red blood cell loss.

Circulatory shock arising from a weakened heart's inability to pump blood effectively.

Circulatory shock caused by a sudden loss of blood vessel tone, leading to widespread vessel dilation and reduced blood return to the heart.

Loss of blood flow to the tissues due to a reduction in blood's ability to carry oxygen.

Loss of blood volume due to fluid loss from the body.

A serious condition where the body's blood pressure drops dangerously low due to an allergic reaction, triggered by an antigen-antibody reaction that causes the release of histamine. Rapid vasodilation and increased capillary permeability lead to fluid and protein loss into the tissues.

A severe condition characterized by widespread bacterial infection in the bloodstream, leading to extensive tissue damage. It can be triggered by various sources like peritonitis or skin infections.

A type of septic shock specifically caused by gram-negative bacteria, primarily colon bacilli. These bacteria release a toxin called endotoxin, which, upon entering the bloodstream, triggers a reaction similar to anaphylaxis.

A stage of shock where the body's compensatory mechanisms are still working, and the body can potentially recover without external intervention.

This stage of shock occurs when the body's compensatory mechanisms fail, and vital organs start to shut down due to lack of oxygen and nutrients.

A stage of shock where the body's compensatory mechanisms are still working to maintain blood pressure and circulation.

A stage where the body's compensatory mechanisms are failing and shock is getting worse, leading to organ damage.

A decrease in heart muscle function due to reduced blood flow to the heart, further reducing cardiac output.

Blood flow to the brain reduces so much that control of blood vessel dilation and constriction is lost.

Tiny blood clots form in small blood vessels, further blocking blood flow.

Increased permeability of blood vessels allows fluid to leak out into tissues, reducing blood volume.

Tissues starved of oxygen and nutrients release harmful substances that worsen shock.

Many cellular processes break down in the body, including the ability to transport nutrients and produce energy.

A severe medical condition where the body's circulatory system fails to deliver enough oxygenated blood to the tissues, leading to organ damage and potential death.

Specialized drugs, such as epinephrine and norepinephrine, that mimic the effects of the sympathetic nervous system, helping to constrict blood vessels and increase heart rate.

The process of replacing lost fluids and blood components in cases of shock.

A condition where the lungs fill with fluid, impairing their ability to function properly.

The ability of the heart to contract and pump blood effectively.

The process of returning blood from the lower extremities to the heart.
