Mindblown: a blog about philosophy.

The department of a hospital responsible for the provision of medical and surgical care to patients arriving at the hospital in need of immediate care. Emergency department personnel may also respond to certain situations within the hospital such cardiac arrests. The emergency department is also called the emergency room or ER.

While there is no formal definition for a “Code,” doctors often use the term as slang to refer to a patient in cardiopulmonary arrest , requiring a team of providers (sometimes called a “code team”) to rush to the specific location and begin immediate resuscitative efforts. The term “Code” derives from the practice at many institutions of…

An organism in the early stages of growth and differentiation, from fertilization to the beginning of the third month of pregnancy (in humans). After that point in time, an embryo is called a fetus.

A blockage or plug that obstructs a blood ‘vessel. Examples of emboli are detached blood clots, clumps of bacteria, and clumps of other foreign material, such as air.

The obstruction of a blood vessel by a foreign substance or a blood clot that travels through the bloodstream, lodging in a blood vessel, plugging the vessel. Foreign substances that can cause embolisms include air bubbles, amniotic fluid, globules of fat, clumps of bacteria, chemicals (such as talc), and drugs (mainly illegal ones). Blood clots are the most common…

Something that travels through the bloodstream, lodges in a blood vessel and blocks it. Examples of emboli are a detached blood clot, a clump of bacteria, and foreign material such as air. Pulmonary emboli are blood clots that have been carried through the blood into the pulmonary artery (the main blood vessel from the heart to the lung) or one…

Elevation of half of the diaphragm, the muscle that separates the chest cavity from the abdomen and that serves as the main muscle of respiration. The elevation of a hemidiaphragm is a significant sign of a problem. That problem may lie below, within or above the diaphragm: An elevated hemidiaphragm may be suspected on the physical examination and confirmed on an X-ray or CT of…

The biomedical field dealing with the study of electric activity in the body. Electrophysiology includes the study of the production of electrical activity and the effects of that electrical activity on the body. See, for example: Electrophysiologic retinal testing ; and Electrophysiologic study of the heart.

A substance that dissociates into ions in solution and acquires the capacity to conduct electricity. Sodium, potassium, chloride, calcium, and phosphate are examples of electrolytes, informally known as lytes. Electrolyte replacement is needed when a patient has prolonged vomiting or diarrhea, and as a response to strenuous athletic activity. Commercial electrolyte solutions are available, particularly for sick children…

A test in which the electrical current generated by the muscle of the stomach is sensed and recorded in a manner very similar to that of an electrocardiogram of the heart. Abbreviated EGG. An EGG is performed by taping electrodes to the skin on the upper abdomen over the stomach. Recordings from the muscle are stored and…
