Online calculators are available that can compute predicted lung volumes, and other spirometric parameters based on a patient's age, height, weight, and ethnic origin for many reference sources.

Oct 13, 2016 · Learn lung volumes (tidal, residual) and capacities (vital, total), normal ranges, and how obstructive vs restrictive diseases affect breathing. Includes charts and video.

Jun 7, 2025 · In this article we will look at the lung volumes and capacities, how they are measured and how they are affected by pathology. It is useful to divide the total space within the lungs into volumes …

Normal Lung Volumes ERV = expiratory reserve volume; FRC = functional residual capacity; IC = inspiratory capacity; IRV = inspiratory reserve volume; RV = residual volume; TLC = total lung …

The below Lung volumes and capacities chart provides the average and normal lung volumes and capacities for men and women. The lung volume is measured using tidal volume (TV), expiratory …

Figure 63.1 – Respiratory Volumes and Capacities: These two graphs show (a) respiratory volumes and (b) the combination of volumes that results in respiratory capacity.

Vital capacity (VC): maximum volume of air that can be exhaled after maximum inhalation. Total lung capacity (TLC): total volume of air in the lungs after a maximum (forced) inhalation. Inspiratory …

Lung capacities are derived from a summation of different lung volumes. The average total lung capacity of an adult human male is about 6 litres of air. Lung volumes measurement is an integral part of …

Discover how factors like age and sex influence your lung capacity. Understand what’s typical for you and why this measure matters for respiratory health.

Spirometry is a diagnostic test that provides different measures of lung capacity. Often used to diagnose chronic obstructive pulmonary disorder (COPD) or asthma, spirometry results are also used to see if …
