Design for positive pressure respirators
Copyright policy )Design for positive pressure respirators
This study deals with the design of a positive pressure respirator using a first order non-linear lung model. The non-linearities considered are non-linear airway resistance, effect of hysteresis and non-constant dead space. The analysis has been carried out using three different waveforms,viz., rectangular, sine and ramp. It is shown that the last two waveforms result in longer inspiratory periods making the actual respirators more reliable in operation.
