| 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) |
|---|
| 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) |
| peak expiratory flow rate | Measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are pefr and pfr. (12 Dec 1998) |
| peak flow rate | Maximum urinary flow rate during voiding as measured by a uroflowmeter. (05 Mar 2000) |
| voiding flow rate | Urinary flow as a function of time during micturition, as graphically recorded by a flow meter. (05 Mar 2000) |
| flow rate | The amount of water that moves through an area (usually pipe) in a given period of time. (05 Dec 1998) |
| average | <statistics> A value that represents the sum of values divided by the number of values in the set. It represents or summarises the relevant features of a set of values. Origin: M.E. Averays, loss from damage to ship or cargo, fr. It. Avaris, fr. Ar. 'awariya, damaged goods, + damage (05 Mar 2000) |
| average megawatt | <physics> One megawatt of capacity produced continuously over a period of one year. 1 MWa = 1 MW x 8760 hours/year = 8,760 Mwh = 8,760,000 kWh. Acronym: MWa (05 Dec 1998) |
| average pulse magnitude | <physics> The amplitude of pulse averaged throughout its duration; identical with peak amplitude for a square wave or pulse without droop. (05 Mar 2000) |
| law of average localization | Visceral pain is most accurately localised in the least mobile viscera and least accurately in the most mobile. (05 Mar 2000) |
| Bingham flow | The flow characteristics exhibited by a Bingham plastic. (05 Mar 2000) |
| blood flow velocity | A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. (12 Dec 1998) |
| gene flow | The movement of genes from one population to another viainterbreeding. (09 Oct 1997) |
| 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) |
| renal blood flow, effective | The amount of blood flowing to the parts of the kidney that are involved with the production of constituents of urine. It is that portion of the total renal blood flow that perfuses functional renal tissue (e.g., the glomeruli). It should be differentiated from renal plasma flow, effective which is based on the amount of plasma rather than on total renal blood. (12 Dec 1998) |
