Abstract :
The use of electrical impedance pneumography (EIP) and respiratory inductive plethysmography (RIP) for noninvasive ventilatory measurements during incremental cycle-ergometer stress testing was evaluated. In three normal subjects and two overweight subjects tidal volume as determined by either technique was linearly related to that resulting from a conventional pneumotachograph from rest to maximal exercise. In the overweight group, values obtained by EIP exhibited considerable variability, mainly as a result of increased motion artifacts. For these subjects, RIP appeared more reliable under the conditions of the present experiment.<>
