- For example, hypoperfusion can be caused when an artery or arteriole that supplies blood to a volume of tissue becomes blocked by an embolus, causing either no blood or at least not enough blood to reach the tissue. Hyperperfusion can be caused by inflammation, producing hyperemia of a body part.

Apr 16, 2024 · Shock is commonly diagnosed when signs of hypoperfusion are associated with low or declining blood pressure. Shock may result from a number of disease processes, including pump failure (cardiogenic), loss of intravascular volume (hypovolaemic), failure of vasoregulation (distributive), or obstruction to blood flow (obstructive).
May 28, 2020 · This article introduces the reader to hypovolaemic shock. It discusses the risk factors, aetiology, investigations, staging, complications, principles of management, education and training. Shock is generally classified according to its cause.
Jul 14, 2022 · Hypovolemia refers to a low extracellular fluid (ECF) volume, often involving a decrease in both water and sodium levels. In order to maintain bodily functions and preserve homeostasis (i.e., a relatively equivalent state), the body requires a specific amount of blood and other bodily fluids.
- Hypovolemia is commonly caused by dysfunction of various organs, such as congestive heart failure or kidney failure. Rarely, neurological disorders...

Apr 21, 2022 · The resulting hypoxia, tissue hypoperfusion and cellular dysfunction can lead to multi-organ failure; if this is not treated in a timely and appropriate manner, it can lead to death. This article gives an introduction to shock with an overview of the condition and its physiological impact on patients.
Mar 6, 2023 · Shock is a state of insufficient blood flow that affects the whole body, putting organs at risk for hypoxia, cellular injury, and ultimately organ failure. The compensated stage of shock refers to the initial stage of shock when the body is still able to compensate for the decrease in tissue perfusion by a series of physiological mechanisms.

Shock is a state of organ hypoperfusion with resultant cellular dysfunction and damage. Mechanisms may involve decreased circulating volume, decreased cardiac output, and vasodilation, sometimes with shunting of blood to bypass capillary exchange beds. Symptoms include altered mental status, tachycardia, hypotension, and oliguria.
Aug 20, 2024 · If left untreated, shock results in sustained multiple organ dysfunction, and end-organ damage with possible death. Tissue hypoperfusion may be present without systemic hypotension, but at the bedside shock is commonly diagnosed when both are present (arterial hypotension and organ dysfunction). [1]
