| a VT is measured by means of a pressure sensor at the test lung, where V T = C x (P max ), and VT is the volume delivered to the test lung C is the isothermal compliance of the test lung Pmax is the maximum pressure measured in the test lung b The accuracy for C and R applies over the ranges of the measured parameters. | |||
