| inspiratory | Relating to or timed during inhalation. (05 Mar 2000) |
|---|---|
| inspiratory capacity | The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the tidal volume and the inspiratory reserve volume. Common abbreviation is ic. (12 Dec 1998) |
| inspiratory centre | The region of the medulla oblongata that is electrically active during inspiration and where electrical stimulation produces sustained inspiration. (05 Mar 2000) |
| inspiratory reserve volume | The extra volume of air that can be inspired with maximal effort after reaching the end of a normal, quiet inspiration. Common abbreviation is irv. (12 Dec 1998) |
| inspiratory stridor | A crowing sound during the inspiratory phase of respiration due to pathology involving the epiglottis or larynx. (05 Mar 2000) |
| apneic pause | Cessation of air flow for more than 10 seconds. See: sleep apnea. (05 Mar 2000) |
| pause | 1. A temporary stop or rest; an intermission of action; interruption; suspension; cessation. 2. Temporary inaction or waiting; hesitation; suspence; doubt. "I stand in pause where I shall first begin." (Shak) 3. In speaking or reading aloud, a brief arrest or suspension of voice, to indicate the limits and relations of sentences and their parts. 4. In writing and printing, a mark indicating the place and nature of an arrest of voice in reading; a punctuation point; as, teach the pupil to mind the pauses. 5. A break or paragraph in writing. "He writes with warmth, which usually neglects method, and those partitions and pauses which men educated in schools observe." (Locke) 6. A hold. See 4th Hold. Synonym: Stop, cessation, suspension. Origin: F, fr. L. Pausa. See Pose. Source: Websters Dictionary (01 Mar 1998) |
| respiratory pause | Cessation of air flow for less than 10 seconds. See: sleep apnea. (05 Mar 2000) |
| compensatory pause | The pause following an extrasystole, when the pause is long enough to compensate for the prematurity of the extrasystole; the short cycle ending with the extrasystole plus the pause following the extrasystole together equal two of the regular cycles. (05 Mar 2000) |
| postextrasystolic pause | The somewhat prolonged cycle immediately following an extrasystole. (05 Mar 2000) |
| preautomatic pause | A temporary pause in cardiac activity before an automatic pacemaker escapes. See: escape. (05 Mar 2000) |
| sinus pause | A spontaneous interruption in the regular sinus rhythm, the pause lasting for a period that is not an exact multiple of the sinus cycle. See: sinus arrest, sinus standstill. (05 Mar 2000) |
| activated clotting time | The most common test used for coagulation time in cardiovascular surgery. (05 Mar 2000) |
| activated partial thromboplastin time | The time needed for plasma to form a fibrin clot following the addition of calcium and a phospholipid reagent; used to evaluate the intrinsic clotting system. (05 Mar 2000) |
| A-H conduction time | Forward conduction of the cardiac impulse from atria to ventricles via the A-V node or any bypass tract, represented in the electrocardiogram by the P-R interval. P-H conduction time is from the onset of the P wave to the first high frequency component of the His bundle electrogram (normally 119 ± 38 msec); A-H conduction time is from the onset of the first high frequency component of the atrial electrogram to the first high frequency component of the His bundle electrogram (normally 92 ± 38 msec); P-A conduction time is from the onset of the P wave to the onset of the atrial electrogram (normally 27 ± 18 msec).
