Minute ventilation
Minute Ventilation
Minute Ventilation (MV), pronounced as /ˈminit ˌven(t)əˈlāSH(ə)n/, is a term used in Respiratory Physiology to describe the total volume of gas (in liters) that is moved in and out of the lungs per minute. It is a crucial parameter in assessing the respiratory status of a patient.
Etymology
The term "Minute Ventilation" is derived from the Latin word "minutus", meaning small, and the Latin word "ventilatio", meaning an action of fanning. The term is used to describe the small amount of air that is ventilated in and out of the lungs every minute.
Calculation
Minute Ventilation is calculated by multiplying the Tidal Volume (TV) - the amount of air inhaled or exhaled during a normal breath - by the Respiratory Rate (RR) - the number of breaths taken per minute. The formula is as follows:
MV = TV x RR
Related Terms
- Alveolar Ventilation: The volume of gas per unit time that reaches the alveoli, the gas-exchange area of the lungs.
- Dead Space Ventilation: The portion of the tidal volume that does not participate in gas exchange because it ventilates anatomical or physiological dead space.
- Respiratory Rate: The number of breaths a person takes per minute.
- Tidal Volume: The volume of air moved into or out of the lungs during a single breath.
