Yes, the duration of inspiration or expiration can vary during forced vital capacity (FVC) and expiratory reserve volume (ERV) maneuvers. This variation is influenced by individual factors such as lung capacity, respiratory muscle strength, and airway resistance. In general, inspiration tends to take longer during FVC, while expiration tends to take longer during ERV.
