The calculation of minute ventilation is simple: MV=TV*Rf or minute volume is equal to tidal volume (amount of air for one breath, ml) multiplied by the respiratory frequency (number of breaths per minute). This table shows normal minute ventilation (liters of air per minute) in healthy subjects at rest .
So what is minute ventilation of a 70kg person. Minute ventilation for a 70 kg person would be 700 X 15 which would be approximately 10500ml. A person requires a minimum of 6 to 8 litres of minute volume for the proper oxygenation of the tissues and the removal of carbon dioxide from the lungs.
Sep 22, 2019 · During physical exercise, respiratory rate depends on the individual and can vary from about 30 to 60 breaths per minute, while minute volume (ventilation) can range from about 50 to 100 liters per minute. How to measure one’s own breathing at rest?
Respiratory minute volume (or minute ventilation or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels. It can be measured with devices such as a IC: Inspiratory capacity: the sum of IRV and TV.
