The answer is calculated by multiplying the rate of respiration times tidal wave. Respiratory minute volume (or also known as minute ventilation or minute volume) is the measurement of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from an individual's lungs per minute. If both tidal volume (VT) and respiratory rate (ƒ or RR) are identified, we can get the minute volume by multiplying the two values. One must also take care to consider the effect of dead space on alveolar ventilation.
