Pulmonary embolism (PE) is typically caused by a blocked artery in your lungs. Imaging studies are essential for the diagnosis of pulmonary embolism. These are not routinely recommended for reperfusion treatment for massive or submassive PE, but can be considered under selected circumstances. Other rare causes of PE have also been identified, including air, tumor embolism, and foreign particles from injections or surgery.2 PE can lead to loss of functional lung tissue, pulmonary infarction, cardiac dysfunction, heart failure, and, ultimately, death.1 The majority of deaths from PE are the result of right ventricular dysfunction and right ventricul… Certain racial groups have increased risk for developing pulmonary embolism. Validated practical clinical decision tools are available to assess pre-test probability of PE. Pulmonary embolism is often caused by blood clots that travel to the lungs from the legs. Physicians who work in emergency departments may use the pulmonary embolism rule-out criteria (PERC). Intermittent pneumatic compression of the calf and thigh is recommended over venous foot pumps when anticoagulants are contraindicated. Doses of these anticoagulants for morbidly obese patients are uncertain, but Enoxaparin 30 mg subcutaneously every twelve hours has been recommended for patients whose BMI is greater than 35.
