摘要： A medical device is provided with an alarm organization. A process for alarm organization of a medical device is also provided. Based on pressure measured values and flow measured values and with a comparison criterion, it is determined whether an elevation of an airway pressure of an anesthesia device or of a ventilator is caused by a coughing event. A visual and/or acoustic output of a warning or alarm is adapted, indicating the elevated airway pressure PAW_High.

摘要： A medical device determines operating situations and a method determines operating situations in a medical device. Based on pressure measured values (99) and flow measured values (97), it is determined whether an elevation of an airway pressure (105) in a medical device is due to a cough event (113) or to a plurality of cough events (117), which indicate an accumulation of secretion. An outputting (41, 42, 44) of a warning (44) or alarm (41, 42) is provided indicating the accumulation of secretion.

摘要： A ventilator (1) determines states with cough attacks and an operating method for a ventilator determines cough attacks. It is determined on the basis of pressure measured values (13, 21, 19) and flow measured values (11, 15, 17) whether consecutive elevations of an airway pressure in a ventilator (1) are due to one cough event or due to a plurality of cough events. A plurality of cough events indicates a state of a cough attack. An output (41, 42, 44) of a warning (44) or alarm (42) is issued indicating the state.

摘要： A method selects the setting of a first operating parameter of a ventilation system that includes devices for feeding breathing air to and removing from a patient (7), a display device (13) with a screen (15) and a computer (11). The method includes presetting a first target value range for a first ventilation parameter, calculating permissible first operating parameter values by the computer (11) for the first operating parameter, so that the first ventilation parameter value is within the target value range if a permissible first operating parameter value is set; calculating values of a preset cost function, which is a function of at least one operating parameter, by the computer (11); selecting a first operating parameter value by the computer (11), at which the value of the cost function has an optimum; and outputting the selected first operating parameter value on the screen (15) of the display device (13).

摘要： An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.

摘要： A method for generating an alarm during the monitoring of a patient with the step of determining a minute volume (MVpat) of the patient, setting a minute volume lower limit (MVlow) and/or a minute volume upper limit (MVhigh), wherein the minute volume (MVpat) is cumulated by means of an increment function into a volume (Vdeficit_kum) when the measured value drops below the minute volume lower limit (MVlow) or exceeds the minute volume upper limit (MVhigh), and an alarm is triggered when the cumulated volume (Vdeficit_kum) exceeds a maximum allowable volume (Vdeficit_apn). Furthermore, the present invention pertains to a device for reducing clinically irrelevant alarms during the monitoring of a patient for carrying out the method according to the present invention.
