Respiratory minute volume refers to the volume of breath per minute. During exercise, this amount increases up to 20 to 30 times the normal value. Exercising regularly improves lung performance and makes breathing easier.
Pulmonary ventilation is 6 liters/minute in resting individual. You have a respiratory rate of 12/minute and tidal volume of 500 ml/minute. During heavy exercise tidal volume increases from 10 % of vital capacity to about 50 % of vital capacity. And respiratory rate increases from 12 to about 40 to 45/ minute. Thus increasing the pulmonary ventilation to about 100 liter/minute.
Tidal Volume x Respiratory Rate
The minute respiratory volume also increases from the normal to support high metabolic rate.this leads to more production of carbon dioxide and its concentration in blood will increase.increased breathing will speed the loss of carbon dioxide to maintain a normal Ph.
in order to increase the amount air moving through the lungs every minute, you need to perform some sort of acute exercise which will also increase your breathing rate and heart rate.
the amount of air breathed in 1 minute. Minute Ventilation = Tidal Volume x Respiratory Rate

Respiratory volume or respiratory minute volume is the volume of air which can be inhaled or exhaled from a person's lung in one minute.It is normally consider when a person on a ventilator for breathing problem due to sickness or injury. It is calculated by taking the tidal volume( or lung volume ) and multiplying it by the respiratory rate( the number of breaths per minute a person is taking).
A change in respiratory rate or tidal volume.... meaning, respiratory rate decreases, maybe becomes apneic, or the tidal volume decreases...or maybe BOTH. Also, a circuit disconnect!
7.7 breaths per minute
Due to the presence of dead space
They increase to meet the higher need of oxygen in the body
You take the patients Respiratory Rate and divide it by the tidal volume averaged over 1 minute.
