The invention concerns a patient's ventilation with breathing mixture The installation comprises a ventilating assembly (10) for delivering said breathing mixture provided with a sensor for measuring the pressure (26) of the delivered mixture and a sensor for measuring the flow rate (28) of the delivered mixture; an inhalation conduit (12); and a device (30) for detecting accidental disconnection of the ventilation circuit comprising processing means (32, 34) for calculating, for each ventilating cycle, an apparent coefficient of the patient's compliance based on the measurements carried out by said pressure and flow rate sensors, using a predetermined formula; means (32, 34) for determining the sign of said compliance coefficient; means (32, 34) for comparing said compliance coefficient to a predetermined positive value; and means (40) for triggering a warning (42, 44) if the compliance coefficient is negative or if the compliance coefficient is higher than said predetermined value. |
