WebApr 27, 2024 · Not only does your breathing rate increase during exercise, but you'll also start taking in larger gulps of air. That amount of air is called the "tidal volume," or the amount of air you can take in during inspiration. That total lung capacity doesn't change much for an individual over time, even with changes to fitness levels. WebThe rate of ventilation of the lungs (in liters/min, L/min) is equal to the volume of air breathed in and out during one breath (in L/breath) multiplied by the rate of breathing (breaths/min). Lung ventilation (L air/min) = tidal volume (TV, liters air/breath) x breathing rate (BR, breaths/min) Figure 4. Lung volumes. WebAs an example, a patient who has a respiratory rate of 25 breaths/min and an average tidal volume of 250 mL/breath has an RSBI = (25 breaths/min)/(0.25 L) = 100 breaths/min/L.
