| tidal creek | Wetlands situated in channels where water flows both directions due to the tides. (09 Oct 1997) |
|---|---|
| tidal drainage | Drainage of the urinary bladder by means of an intermittent filling and emptying apparatus. (05 Mar 2000) |
| tidal influence | Exposure of intertidal land to periodic inundation of seawater twice daily due to the rising and falling of the tides. (09 Oct 1997) |
| tidal prism | The change in the volume of water covering an area, such as a wetland, between a low tide and the subsequent high tide. (09 Oct 1997) |
| tidal regime | The range of elevations in a wetland experiencing a specific pattern of tidal inundation. (09 Oct 1997) |
| tidal waters | Those waters that rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun. Tidal waters end where the rise and fall of the water surface can no longer by practically measured in a predictable rhythm due to masking by hydrologic, wind, or other effects. Source: 33 CFR |
| tidal wave | The wave between the percussion wave and the dicrotic wave in the downward limb of the arterial pulse tracing. (05 Mar 2000) |
| end-tidal | at the end of a normal expiration. (05 Mar 2000) |
| end-tidal sample | A sample of the last gas expired in a normal expiration, ideally consisting only of alveolar gas. (05 Mar 2000) |
| atomic volume | The atomic weight of an element divided by its density in the solid state; the volume of the gram-atomic weight of a solid element. (05 Mar 2000) |
| blood volume | Volume of circulating blood. It is the sum of the plasma volume and erythrocyte volume. (12 Dec 1998) |
| blood volume determination | Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight. (12 Dec 1998) |
| blood volume nomogram | A nomogram used to predict blood volume on the basis of the individual's weight and height. (05 Mar 2000) |
| cardiac volume | The volume of the heart, usually relating to the volume of blood contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is stroke volume. (12 Dec 1998) |
| packed cell volume | <haematology> Measurement of the proportion of the blood occupied by the red blood cells. Normal values are 40-54% in males, 35-47% in females. (13 Nov 1997) |
