| 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) |
| Buck's extension | Apparatus for applying longitudinal skin traction on the leg through contact between the skin and adhesive tape; friction between the tape and skin permits application of force, which is applied through a cord over a pulley, suspending a weight; elevation of the foot of the bed allows the body to act as a counterweight. Synonym: Buck's traction. (05 Mar 2000) |
| paraplegia in extension | Paralysis of the legs, maintained in an extended position by hypertonic extensor muscles. (05 Mar 2000) |
| ridge extension | An intraoral surgical operation for deepening the labial, buccal, and/or lingual sulci; it is performed to increase the intraoral height of the alveolar ridge in order to assist denture retention. (05 Mar 2000) |
| crossed extension reflex | Extension of the contralateral hind limb when the paw of an animal is painfully stimulated or the central cut end of an afferent nerve, e.g., the peroneal, is stimulated; sometimes occurs in humans upon tapping the skin. (05 Mar 2000) |
| primer extension | A technique for determining the 5'-untranslated region of a specific mRNA molecule. Uses an oligonucleotide complementary to the known RNA sequence as a primer for cDNA synthesis via reverse transcriptase. (05 Mar 2000) |
| skeletal extension | Traction pull on a bone structure mediated through pin or wire inserted into the bone to reduce a fracture of long bones. Synonym: skeletal extension. (05 Mar 2000) |
| nail extension | An obsolete method of extension, by a weight on a nail or pin in the distal fragment of a fracture. (05 Mar 2000) |
| extension | 1. <orthopaedics> The movement by which the two elements of any jointed part are drawn away from each other. 2. <anatomy> A movement which brings the members of a limb into or toward a straight relation. Origin: L. Extensio (18 Nov 1997) |
