The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score , which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out the risk of PE in people when the physician has already ...
A related term is embolism, which describes the phenomenon of an embolus lodging in a vessel and creating a blockage. [2] An embolism is technically a consequence of an embolus, but the terms are sometimes used interchangeably. [6] Both emboli and embolisms are usually named according to their composite substance.

Generally speaking the risk for thrombosis increases over the life course of individuals, depending on life style factors like smoking, diet, and physical activity, the presence of other diseases like cancer or autoimmune disease, while also platelet properties change in aging individuals which is an important consideration as well. [31]
An embolism can cause partial or total blockage of blood flow in the affected vessel. [2] Such a blockage (vascular occlusion) may affect a part of the body distant from the origin of the embolus. An embolism in which the embolus is a piece of thrombus is called a thromboembolism. An embolism is usually a pathological event, caused by illness ...
Prevention of atherosclerosis, which is a major risk factor of arterial embolism, can be performed e.g. by dieting, physical exercise and smoking cessation. [ 6 ] In case of high risk for developing thromboembolism, antithrombotic medication such as warfarin or coumadin may be taken prophylactically.
People who maintain or start physical activity of any intensity after receiving a dementia diagnosis may be at a decreased risk for all-cause mortality, a new study suggests.
These include a sedentary lifestyle, prior surgery, trauma, history of DVT, and hypertension. [31] A sedentary lifestyle and lack of movement are critical modifiable risk factors for PE. [ 32 ] Immobility reduces the rate of leg muscle contraction, enhancing thrombus formation in vessels of the calves that may propagate to the lungs. [ 33 ]
Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
