title: Effects of varying inspiratory flow waveform and time in intermittent positive pressure ventilation. I: Introduction and methods.
abstract: A general review of the physiological alterations with artificial ventilation is presented with particular emphasis on the alteration of inspiratory time and flow waveform. The general methods and physiological calibration procedures used in a more elaborate study of inspiratory time and waveform effects are described, with the results of testing these methods showing that the model is satisfactory.
