| functional residual capacity | The volume of air remaining in the lungs at the end of a normal, quiet expiration. It is the sum of the residual volume and the expiratory reserve volume. Common abbreviation is frc. (12 Dec 1998) |
| blood pressure, high | High blood pressure (hypertension) is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg. High blood pressure is also called the silent killer. Chronically high blood pressure can cause blood vessel changes in the back of the eye (retina), thickening of the heart muscle, kidney failure, and brain damage. No specific cause for high blood pressure is found in 95% of patients. High blood pressure is treated with salt restriction, regular aerobic exercise, and medications. (12 Dec 1998) |
| blood sugar, high | Elevated levels of blood glucose (hyperglycaemia) can be found in a number of conditions. The hyperglycaemia leads to spillage of glucose into the urine, hence the term sweet urine. (Diabetes mellitus means sweet urine. ) (12 Dec 1998) |
| cardiac output, high | A state of elevated cardiac output. Conditions that lower peripheral vascular resistance, such as anaemia, arteriovenous fistulas, thyrotoxicosis, and pregnancy, are among the most important factors augmenting the venous return and therefore elevating cardiac output. Increased cardiac output also occurs in muscular exercise, fever, and severe anoxia. (12 Dec 1998) |
| radiotherapy, high-energy | Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; X-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle.

| mean higher high water | <marine biology> The average height of the higher high water over a 19-year period. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |
| mean high water | <marine biology> The average height of the high water over a 19-year period. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. All high-waters heights are included in the average where the type of tide is either semidiurnal or mixed. Only the higher high-water heights are included in the average where the type of tide is diurnal. So determined, mean high water in the latter case is the same as mean higher high water.

| chromatography, high pressure liquid | Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed. (12 Dec 1998) |
| pregnancy, high-risk | Pregnancy in which the mother and/or foetus are at greater than normal risk of morbidity or mortality. Causes include lack of adequate prenatal care, previous obstetrical history, pre-existing maternal disease or pregnancy-induced disease, and multiple gestation, as well as advanced maternal age.
