| innate heat | In ancient Greek medicine, the heat of the heart sustained by the pneuma and distributed by the arteries throughout the body. (05 Mar 2000) |

| unit of heat | Calorie (gram calorie; kilocalorie) Synonym: British thermal unit. Synonym: joule. (05 Mar 2000) |
| latent heat | The amount of heat that a substance may absorb without an increase in temperature, as in conversion from solid to liquid state (ice to water at 0캜), or from liquid to gaseous state (water to steam at 100캜). Compare: sensible heat. (05 Mar 2000) |
| anaesthetic shock | Shock produced by the administration of anaesthetic drug(s), usually in relative overdosage. (05 Mar 2000) |
| anaphylactic shock | <immunology> A serious, often life-threatening allergic reaction that is characterised by low blood pressure, shock (poor tissue perfusion) and difficulty breathing. (27 Sep 1997) |
| anaphylactoid shock | A reaction that is similar to anaphylactic shock, but which does not require the incubation period characteristic of induced sensitivity (anaphylaxis); it is unrelated to antigen-antibody reactions. Synonym: anaphylactoid crisis, pseudoanaphylactic shock. (05 Mar 2000) |
| break shock | The shock produced by breaking a constant current passing through the body. (05 Mar 2000) |
| cardiac shock | A form of shock (inadequate delivery of oxygen to the tissues) that occurs secondary to the weakened pumping function of the heart. This condition may be precipitated by myocardial infarction or cardiomyopathy. Treatment includes fluid restriction, diuretics, vasopressors (dopamine) to support the blood pressure and the use of intravenous medications (dobutamine) which stimulate the heart to contract more forcefully. (27 Sep 1997) |
| cardiogenic shock | A form of shock (inadequate delivery of oxygen to the tissues) that occurs secondary to the weakened pumping function of the heart. This condition may be precipitated by myocardial infarction or cardiomyopathy. Treatment includes fluid restriction, diuretics, vasopressors (dopamine) to support the blood pressure and the use of intravenous medications (dobutamine) which stimulate the heart to contract more forcefully. (27 Sep 1997) |
| cardiopulmonary obstructive shock | <cardiology> This term describes a number of conditions that involve a severe disturbance of the cardiopulmonary circuit resulting in shock (inadequate delivery of oxygen to the tissues). Examples include: pulmonary embolism, pericardial tamponade, pneumothorax and constrictive pericarditis. (27 Sep 1997) |
| vasogenic shock | Shock resulting from depressed activity of the higher vasomotor centres in the brain stem and the medulla, producing vasodilation without loss of fluid so that the container is disproportionately large. In oligaemic shock, blood volume is reduced; in both, return of venous blood is inadequate. (05 Mar 2000) |
| reversible shock | Shock that will respond to treatment and from which recovery is possible. (05 Mar 2000) |
| chronic shock | The state of peripheral circulatory insufficiency developing in elderly patients with a debilitating disease, e.g., carcinoma; a subnormal blood volume makes the patient susceptible to haemorrhagic shock as a result of even a moderate blood loss such as may occur during an operation. (05 Mar 2000) |
| wet shock | A severe condition that occurs when the level of blood glucose (sugar) drops quickly. The signs are shaking, sweating, dizziness, double vision, convulsions, and collapse. Insulin shock may occur when an insulin reaction is not treated quickly enough. See: hypoglycaemia. (09 Oct 1997) |
| cultural shock | A form of stress associated with the beginning of an individual's assimilation into a new culture vastly different from that in which he or she was raised. (05 Mar 2000) |
