While there is controversy regarding the use of US of the IVC to accurately determine volume status, measurements consistent with the extremes of volume status (like the elevated CVP in this case) are believed to be more reliable [51].
Firstly, this new approach can accurately measure volume rather than rough indices (e.g., greatest diameter [ 5], approximate BML volume [ 6, 11]).
An accurately measured volume of the resulting solution equivalent to 10.0 mg of EPH was transferred into 100 mL volumetric flask, and diluted to volume with distilled water.
One can calculate accurately the volume fraction by counting the resulting number distribution of individual nanoparticles using confocal microscope image analysis accompanied by molecular dynamics simulation [23].
An accurately measured volume equivalent to 5 mg was dissolved in 25 mL methanol and acetonitrile for method A and B, respectively.
Guarracino et al. have reported that IJV distensibility [(diamax − diamin)/diamin × 100] accurately predicts volume responsiveness in mechanically ventilated septic patients [19].
An accurately measured volume of ophthalmic solution (Olodin, FDC Limited, Aurangabad, India), equivalent to about 10 mg of OLO, was transferred to a 100 mL 163 volumetric flask and diluted with diluent to the volume.
An accurately measured volume of mixed content of 10 ampoules equivalent to 1.0 g of phenytoin base transferred into 100-mL volumetric flask, and then diluted to the mark with methanol.
Several studies have confirmed that respiratory variations of the superior and inferior vena cava diameters (collapsibility index [CI] and distensibility index [DI]) accurately reflect volume responsiveness in mechanically ventilated patients [9, 10].
An accurately measured volume of the mixed contents of 10 ampoules equivalent to 10.0 mg of orphenadrine citrate were transferred into 100 mL volumetric flask, and diluted to 100 mL with distilled water.
