'''Tidal volume''' (symbol '''V<sub>T</sub>''' or '''TV''') is the volume of air inspired and expired with each passive breath.<ref>{{Citation|last1=Haddad|first1=Moshe|title=Physiology, Lung|date=2021|url=http://www.ncbi.nlm.nih.gov/books/NBK545177/|work=StatPearls|place=Treasure Island (FL)|publisher=StatPearls Publishing|pmid=31424761|access-date=2021-03-17|last2=Sharma|first2=Sandeep}}</ref> It is typically assumed that the volume of air inhaled is equal to the volume of air exhaled such as in the figure on the right. In a healthy, young human adult, tidal volume is approximately 500&nbsp;ml per inspiration at rest or 7&nbsp;ml/kg of body mass.<ref>Beardsell, I et al: ''MCEM Part A:MCQs'', page 33, Royal Society of Medicine Press, 2009</ref>
