The values for residual volume and total lung capacity are generally decreased in restrictive lung disease.
2.
This reduces the amount of residual volume in the bladder, increases the urinary flow rate and decreases the voiding time.
3.
Determination of the " residual volume " is more difficult as it is impossible to " completely " breathe out.
4.
Not all air is expelled from the lungs even after a forced breath out; the remainder of the air is called the residual volume.
5.
In 1964, Sachithanandan and JF Nunn et al . were the first investigators to demonstrate age-dependent airway closure in humans whilst breathing at residual volume.
6.
As a perception of volume mishandling, a voiding diary ( to assess voided volumes and frequency of voiding ) and a post-void residual volume would be valuable information.
7.
Therefore, measurement of the residual volume has to be done via indirect methods such as radiographic planimetry, body plethysmography, closed circuit dilution ( including the helium dilution technique ) and nitrogen washout.
8.
The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal.
9.
The total lung capacity ( TLC ), functional residual capacity ( FRC ), residual volume ( RV ), and vital capacity ( VC ) are all values that can be tested using this method.
10.
Standard errors in prediction equations for residual volume have been measured at 579 mL for men and 355 mL for women, while the use of 0.24 * FVC gave a standard error of 318 mL.
