Webminute volume (RMV). Mathematically, respiratory minute volume is the product of tidal volume and the respiratory cycle frequency: RMV = (TV x BPM) A normal adult value for RMV is (500 mL/breath) x (12 breaths/minute) = 6 L/min. Respiratory minute volume varies with the body’s need for oxygen and the need for excreting carbon dioxide. During ...
