Normal tidal volume, average tidal volume, tidal volume in adults

Tidal volume (sometimes known as “Vt”) is measured as the air volume breathed in during a single inhalation or exhalation from the lungs. In other words, tidal volume is a difference between volumes after a normal inhalation and a normal exhalation.

Normal tidal volume in adults at rest is about 500-600 ml or 17-20 oz of air. Most people breathe deeper and faster than these medical norms. As a result, they have reduced body oxygen levels.

The normal tidal volume numbers are much smaller in newborn, toddlers, infants, and children, down to about 100-150 ml due to smaller lungs.

Medical research suggests there is some correlation between tidal volume and health. It is common that, with development of chronic diseases, such as heart disease, cancer, asthma, COPD, diabetes, HIV-AIDS, and many others, tidal volume becomes larger. The same is true about breathing frequency. Sick people breathe faster and with greatly increased minute volumes at rest.

You can find more facts related to minute ventilation, respiratory rates, and get an idea about tidal volume in healthy people and people with cancer, heart disease, asthma, COPD, lung disease, diabetes, and many other conditions on pages of NormalBreathing.com.

Another webpage with this URL: http://www.e-breathing.com/respiration/tidal-volume/ tidal volume – provides some extra details and a chart related to medical norms and values for tidal volume in people with symptoms and health problems.

Normal values for tidal volume:
– during exercise: about 2 L
– pranayama: 3-4 L (close to maximum inhalation and exhalation in the lungs)
– firebreath (hatha yoga exercise): 150-200 mL if this yoga exercise is done correctly.
