Abstract: An exhalation valve arrangement (22) for a ventilation apparatus for artificial ventilation of patients is flow-capable in an exhalation flow direction (E) and encompasses: an upstream respiratory gas conduit (54) that extends along a first conduit path (K1) and is connected or connectable to a portion, coming from the patient, of the exhalation line; a downstream respiratory gas conduit (58) that extends along a second conduit path (K2) and is connected or connectable to a respiratory gas sink (U); a valve subassembly (63) which comprises a valve body (64) and a valve seat (66) and which is provided between the upstream and the downstream respiratory gas conduit (54, 58) in such a way that, in the context of a predetermined first respiratory gas overpressure in the upstream respiratory gas conduit (54) relative to the downstream respiratory gas conduit (58), it permits an expiratory respiratory gas flow from the upstream respiratory gas conduit (54) into the downstream respiratory gas conduit (58); and in

Abstract: A method for determining for a female a time interval for using contraception is disclosed, the method comprising receiving in a processor (11), from a sensor system (22) of a wearable device (2) of the female, physiological data of the female, generating cycle phase probabilities of the female being in one or more cycle phases of her menstrual cycle on a given day, by use of a machine learning model and the physiological data, determining the time interval for using contraception using the physiological data, the cycle phase probabilities, and pre-determined cycle phase probability thresholds, and generating a message for the female comprising the time interval for using contraception.

Abstract: The present artificial respiration ventilator (10) comprises, inter alia, a flow sensor arrangement (44, 48) for quantitatively detecting a gas flow in a breathing line arrangement (30), comprising a distal flow sensor (48) located farther from the patient end of the ventilation line arrangement (30). and a proximal flow sensor (44) located closer to the patient end of the ventilation line arrangement (30), and has a control device (18) at least for processing measurement signals of the flow sensor arrangement (44, 48), wherein the control device (18) is designed for error detection based on the measurement signals of the distal (48) and/or the proximal sensor (44).
