| voiding flow rate | Urinary flow as a function of time during micturition, as graphically recorded by a flow meter. (05 Mar 2000) |
|---|---|
| maximal expiratory flow rate | <chest medicine, physiology> Measurement of rate of airflow during the first liter expired after the first 200 ml have been exhausted during a forced vital capacity determination. Common abbreviations are MEFR, FEF 202-1200, and fef 0.2-1.2. Acronym: MEFR (21 Jun 2000) |
| maximal midexpiratory flow rate | Measurement of rate of airflow over the middle half of a forced vital capacity determination (from the 25 percent level to the 75 percent level). Common abbreviations are mmfr and fef 25%-75%. (12 Dec 1998) |
| voiding cystogram | <investigation, radiology> A special X-ray study which allow visualisation of the bladder and urethra on X-ray. A catheter is placed into the urethra, through which a radio-opaque contrast material is injected. Subsequent X-rays will show the anatomy of the bladder and urethra. (27 Sep 1997) |
| maximal | The greatest possible, allowable or appreciable, the reverse of minimal. (18 Nov 1997) |
| maximal dose | <pharmacology> The largest amount of a drug or physical procedure that an adult can take with safety. (05 Mar 2000) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| maximal Histalog test | A test for measurement of maximal production of gastric acidity or anacidity; it is similar to the histamine test, but uses Histalog (betazole hydrochloride), an analogue of histamine. Synonym: maximal Histalog test. (05 Mar 2000) |
| maximal stimulus | A stimulus strong enough to evoke a maximal response. (05 Mar 2000) |
| maximal voluntary ventilation | Measure of the maximum amount of air that can be breathed in and blown out over a sustained interval such as 15 or 20 seconds. Common abbreviations are mvv and mbc. (12 Dec 1998) |
| point of maximal impulse | The point on the chest wall at which the maximal cardiac impulse is seen and/or felt. (05 Mar 2000) |
| abortion rate | The number of abortions per 1000 terminated pregnancies during a given period of time. (05 Mar 2000) |
| age-specific rate | A rate for a specified age group, in which the numerator and denominator refer to the same age group. (05 Mar 2000) |
| attack rate | A cumulative incidence rate used for particular groups observed for limited periods under special circumstances, such as during an epidemic. (05 Mar 2000) |
| average flow rate | <physiology> The flow rate determined by dividing the total volume passed in a time period divided by the time period, usually quoted in mls per minute. (05 Mar 2000) |
