Abstract: In a method for nasal ventilation and relevant apparatus, particularly for flow-synchronized neonatal assisted ventilation, wherein F(t) is a signal proportional to the ventilation flow, the following steps are performed: (a) inspiration, having a time length Ti, during which air is introduced at an inspiration pressure; (b) expiration, having a time length Te, during which the introduction of air is interrupted; (c) return to step (a); with a flow threshold Ftr, during the expiration step (b) the following steps are provided: (b1) a waiting step having a time length ? before activation of computation of the leakages; and (b2) a step of leakage computation, having a time length ?, so that ?+?=Te, wherein if a normalized signal F? (t), obtained by a processing by way of an algorithm of the surveyed signal F(t), exceeds the threshold Ftr, a spontaneous respiration activity is detected and the inspiration step (a) is reactivated.

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.
