Tidal volume and breathing frequency

WebbIn a typical terrestrial mammal the volume of air inhaled and exhaled in one breath is in the range of 10–15% of TLC. In marine mammals, tidal volume is typically greater than 75% … WebbDuring exercise, tidal volume increases as the depth and rate of breathing increase. This has the effect of taking more oxygen into the body and removing more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 liters of air) when you are resting up to about 40-60 times a minute (100 liters of air) …
