Design for positive pressure respirators

Medical & Biological Engineering, 1972
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

Intermittent Positive Pressure Respiration in Infants with Poliomyelitis

Acta Paediatrica, 1958
SummaryTwelve infants suffering from life‐threatening complications of poliomyelitis were treated with intermittent positive pressure respiration with 5 survivals. Indications for therapy, details of treatment, results and complications are discussed. Despite the special difficulties encountered in this age group, it is felt that effective treatment is

Servo respirator constructed from a positive-pressure ventilator

Journal of Applied Physiology, 1976
We have constructed an electronically controlled respirator from three commercially available components: a positive-pressure ventilator, a recorder pen motor, and a differential amplifier. Using negative feedback derived from a tracheal pressure signal, the instrument functions as a servo respirator which provides precise control of tracheal pressure.
