ABSTRACT:
A constant flow and controlled-ventilation pulmotor responsive to the respiration pressure in the respiratory circuit of a patient in which the intervention of a processor causes visually observable information to be presented to the operator to allow immediate control of mechanical ventilation and the adaptation of same to the clinical requirements of the patient. First, second and third desired pressure, time and flow rate parameters are set by a control board. A maximum pressure-responsive valve is responsive to the first pressure, time, and flow rate parameters, a minimum pressure-responsive valve is responsive to the second pressure, time, and flow rate parameters, and a solenoid valve is responsive to third pressure, time, and flow rate parameters. A transducer continuously detects in real time the value of the instantaneous pressure in the respiratory circuit of the patent and supplies an electrical signal indicative thereof to the processor. The processor processes the signals from the transducer and the control board and respectively visualizes them on a video display as breathing waveforms and as numerals representative of the first, second, and third sets of parameters.
