Abstract:
A method and apparatus to determine residual long volume of a subject is disclosed. Physical characteristics of water in a pool and surrounding air barometric pressure is determined. A body of the subject is completely submerged in the pool of water at a known depth and exhales. The subject then moves to a shallower depth in the water and completely exhales air into an air measuring device. The residual lung volume is then determined and displayed based on the water characteristics, barometric air pressure, the amount of air exhaled into the air measuring device, and the depths of the subject during exhalation.
