Inspiratory capacity (IC), inspiratory reserve volume (IRV), tidal volume (V T), and breathing frequency (F b) responses versus minute ventilation during constant work rate exercise across the continuum of health and COPD severity. The IC at rest and throughout exercise progressively decreases with advancing disease.
inspiratory capacity (IC) throughout rest and exercise. Despite the valuable insight that the IC provides, there are no established recommendations on how to perform the maneuver during exercise and how to analyze and interpret the data.
There are five pulmonary capacities that are the sum of two or more lung volumes; Inspiratory Capacity (IC), Expiratory Capacity (EC), Functional Residual Capacity (FRC), Total Lung Capacity (TLC), and Vital Capacity (VC). Note that RV, FRC, and TLC cannot be measured by spirometry.
The vital capacity (VC) is the amount of air that is exchanged between inhaling and exhaling when the person tries to inhale and exhale as much as they can. It can be measured by adding the tidal volume plus the inspiratory reserve volume plus the expiratory reserve volume.

There are four respiratory volumes (determined by spirometry) required to indirectly calculate the respiratory capacity: The four lung capacities are calculated as follows:

15 Αυγ 2023 · The calculation for inspiratory capacity is the tidal volume (the amount of air you casually breathe in) plus the inspiratory reserve volume (the amount of air you forcefully breathe in after a normal inhalation). This equation is written as: TV + IRV = IC.
