Study Notes

Spirometer and Lung Volumes

A spirometer is a device that measures lung volumes and capacities.
The normal depth of breathing is represented by Tidal Volume (TV).
The normal value for Inspiratory Reserve Volume (IRV) is 3000 mL.
The Expiratory Reserve Volume (ERV) is the additional volume of air that can be expired out forcefully, after normal expiration.
The Residual Volume (RV) is the volume of air remaining in the lungs even after forced expiration.
