Lung Functions in Menopausal Obese Women After COVID 19 Recovery

Spirometry assesses the integrated mechanical function of the lung, chest wall, respiratory muscles, and airways by measuring the total volume of air exhaled from a full lung (total lung capacity \[TLC\]) to maximal expiration (residual volume \[RV\]). This volume, the forced vital capacity (FVC) and the forced expiratory volume in the first second of the forceful exhalation (FEV1), should be repeatable to within 0.15 L upon repeat efforts in the same measurement unless the largest value for either parameter is less than 1 L. In this case, the expected repeatability is to within 0.1 L of the largest value.
