residual volume

  • This is because closing capacity is equal to closing volume plus residual volume.
  • It can not be estimated through spirometry, since it includes the residual volume.
  • The following method has the advantage of needing no volume information of the body (see the note about the residual volume below).
  • The residual volume in the lungs can add error if not measured directly.
  • Determination of the residual volume is more difficult as it is impossible to "completely" breathe out.
  • Most lab results such as urine analysis, cystometry and postvoid residual volume are normal.
  • The values for residual volume and total lung capacity are generally decreased in restrictive lung disease.
  • The blood shift causes the lungs' capillary volume to expand resulting in a reduction of the residual volume and thus in an increase of the maximum possible depth.
  • Studies have shown that the intraoperative use of this guiding method may reduce the tumour residual volume and prolong progression-free survival in patients suffering from this disease.
  • 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.
  • Exhaled volumes are measured by a pulmonary function test or simple spirometry, leading to an elevated residual volume and a measurement of forced expiratory volume.
  • The closing capacity is greater than the residual volume (RV), the amount of gas that normally remains in the lungs during respiration, and specifically, after forced expiration.
  • A meta-analysis of people with prostate enlargement and healthy males showed a significant reduction of residual volume, while a trend towards an improved urinary flow rate and decreased voiding time was found.
  • Unlike other common obstructive disorders such as asthma or emphysema, bronchitis rarely causes a high residual volume (the volume of air remaining in the lungs after a maximal exhalation effort).
  • The stomach is "tubulized" with a residual volume of about 150 ml.
  • This situation, in which there is residual volume in the bladder is prone to complications such as cystitis and bladder stones, also commonly found in patients with benign prostate hyperplasia.
  • 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.
  • The maximum diving depth of the free diver is mainly determined by the ratio of the residual volume (RV) to the total lung capacity (TLC).
  • 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.
  • 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.
