The definition of SIRS is shown below: SIRS is the presence of two or more of the following: abnormal body temperature, heart rate, respiratory rate, or blood gas, and white blood cell count. Sepsis is defined as SIRS in response to an infectious process. [48]
Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1 ] [ 2 ] It is one of four categories of shock , a condition where there is not enough oxygen -carrying blood to meet the metabolic needs of the cells ...
A blood gas test or blood gas analysis tests blood to measure blood gas tension values and blood pH.It also measures the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

Septic thrombophlebitis is characterized by a bacterial or fungal infection that coexists with venous thrombosis.Deep veins or superficial veins could be affected. Septic thrombophlebitis can manifest as anything from a harmless condition that affects a small area of superficial veins to serious systemic infections that cause shock and even death.
Venous blood is typically colder than arterial blood, [1] and has a lower oxygen content and pH. It also has lower concentrations of glucose and other nutrients and has higher concentrations of urea and other waste products. The difference in the oxygen content of arterial blood and venous blood is known as the arteriovenous oxygen difference.
A blood clot could be a broken thrombosis that got clotted to the blood vessel wall. Infarctions are divided into two types according to the amount of blood present: White infarctions ( anemic infarcts ) affect solid organs such as the spleen , heart and kidneys wherein the solidity of the tissue substantially limits the amount of nutrients ...
The definition of refractory shock or vasodilatory shock varies. In 2018, the American College of Chest Physician stated that it is presents if there is an inadequate response to high-dose vasopressor therapy defined as ≥ 0.5 mg/kg/min norepinephrine-equivalent dose. [4]
