The lung capacity calculator helps you find the respiratory volumes of your or your patient’s lungs.
Scroll down if you’re not sure how to calculate Total Lung Capacity (TLC), vital capacity (VC), inspiratory capacity (IC), and functional residual volume (FRS).
The uses four lung volume measurements from spirometry, a ventilatory pulmonary function test:
- IRV – Inspiratory Reserve Volume;
- TV – Tidal Volume;
- ERV – Expiratory Reserve Volume;
- RV – Residual Volume.
