Abstract
A medical device has features for an alarm organization with regard to the time course of a minute volume. The alarm organization features are configured for undershoots (117, 217) and exceedances (118, 218) of a comparison minute volume (208) over a period of time (1000). The features make it possible to avoid overreacting to non-critical situations.
Claims20
A medical device with alarm organization, the medical device for ventilating a living being, the medical device comprising:
- a control unit;
- a breathing gas supply system comprising a means for performing controlled ventilation of a patient, which comprises a gas conveying unit, an inspiratory dosing unit and an expiratory valve;
- a tube system configured to supply breathing gas quantities to the living being and to convey breathing gas quantities from the living being;
- and
- a sensor system comprising a flow rate sensor system which is arranged operatively connected to the breathing gas supply system and/or the tube system and is configured to continuously detect one or more flow rate measured values and to provide the flow rate measured values to the control unit as measured values,
- wherein the control unit is configured, in cooperation with the sensor system, the breathing gas supply system and the tube system, to control a supply and dosage of inspiratory breathing gas quantities and to control expiratory breathing gas quantities for ventilation of the living being,
- wherein the control unit is configured to determine a minute volume based on the measured values of the flow rate sensor system,
- wherein the control unit is configured to carry out an organization of alarms during a course of ventilation over a plurality of inspiratory time durations, wherein the alarms relate to the minute volume, and
- wherein the control unit is configured to determine, during the course of ventilation, a special situation of the minute volume in relation to a time course of a comparison minute volume and the organization of alarms is based on the special situation such that the control unit is configured to adjust an alarm depending on the special situation of the minute volume.

A medical system comprising:
- a ventilator device or anesthesia device for ventilating a living being, the ventilator device or anesthesia device comprising:
- a breathing gas supply system comprising a gas conveying unit, an inspiratory dosing unit and an expiratory valve;
- a tube system configured to supply breathing gas quantities to the living being and to convey breathing gas quantities from the living being;
- and
- a sensor system comprising a flow rate sensor system which is arranged operatively connected to the breathing gas supply system and/or the tube system and is configured to continuously detect one or more flow rate measured values and to provide the flow rate measured values to the control unit as measured values;
- and
- a control unit, which is configured, in cooperation with the sensor system, the breathing gas supply system and the tube system, to control a supply and dosage of inspiratory breathing gas quantities and to control expiratory breathing gas quantities for ventilation of the living being, wherein the control unit is configured to determine a minute volume based on the measured values of the flow rate sensor system;
- and
- a data module operatively connected to the control unit, the data module comprising apnea special situation comparison data, which comprises a comparison minute volume relation, a comparison minute volume reference value, a comparison minute volume lower threshold value or a comparison minute volume time course based on a living being apnea comparison situation for an apnea reference situation duration,
- wherein the control unit is configured to determine from a patient current minute volume an apnea situation during a course of ventilation, and to compare the patient current minute volume to the apnea special situation comparison data and to adjust an alarm organization based on the comparison of the patient current minute volume to the apnea special situation comparison data.
