Tidal Volume
Tidal Volume (Pronunciation: Tie-dal Vol-yoom) is a term used in the field of Pulmonology to describe the amount of air that is inhaled or exhaled from the lungs during normal breathing.
Etymology
The term "Tidal Volume" is derived from the word "tide", which refers to the ebb and flow of sea levels. This is a metaphor for the ebb and flow of air in and out of the lungs during normal respiration.
Definition
Tidal Volume is the volume of air displaced between normal inhalation and exhalation when extra effort is not applied. In a healthy, young human adult, tidal volume is approximately 500 milliliters per breath. This value can be higher in men than in women and it is lower in children and infants.
