Web21 jul. 2016 · Bedside spirometry measures forced vital capacity (FVC) and forced expiratory volume (FEV), allowing calculation of other pulmonary function indices, such as timed forced expiratory flow rate. Depending on the type of spirometer used, bedside spirometry can also allow direct measurement of vital capacity and tidal volume.

WebThe Forced Vital Capacity measures the maximal volume of gas that can be expired as forcefully and rapidly as possible after a maximal inspiration to total lung capacity. This measurement will help determine if the patient has any obstructive or … WebVital capacity (VC) is frequently measured by two different methods (inspiration vs expiration). The difference in results is not readily available in the literature. The VC was measured both ways in 60 subjects, including many with obstructive airway disease. Only a minor difference in mean VC (75 ± ml SD) was found. the taunting hour loud house deviantart
