Abstract: A measuring system (60, 69, 68) determines gas concentrations as part of a monitoring system for monitoring the breathing gas supply of an aircraft pilot in an aircraft. The measuring system (60, 69, 68) is capable of determining an oxygen concentration (909) in the breathing gas mixture (10) of the aircraft pilot under variable operating temperatures (699) during flight operations of the aircraft.

Abstract: A measuring system (60, 69, 68) determines gas concentrations as part of a monitoring system for breathing gases or a breathing gas mixture (10). The measuring system (60, 69, 68) is capable of determining an oxygen concentration (908) in the breathing gas mixture (10) under variable pressure conditions (599).

Abstract: A monitoring system (100) has an associated gas collection device (81) for use in a breathing gas supply in aircraft. A process (900) provides coordinated operation of the monitoring system (100) and gas collection device (81). During coordinated operation of the monitoring system (100) and gas collection device (81), a module (50) for gas transportation is activated (902) and the module (55) for gas quantity control is activated (903) for supplying defined quantities (80) of breathing gas mixture to the gas collection device (81) with the gas collection containers (82, 83, 84).

Abstract: A monitoring system (100) with a gas measuring device (72) as well as to a process for operating a monitoring system (100). The monitoring system (100) is used to monitor the breathing gas supply of an airplane pilot in an aircraft. The principal components in the breathing gas (10) are formed by air (5), i.e., essentially defined quantities of oxygen, carbon dioxide, nitrogen and moisture or water vapor. On the one hand, information on the exact quantity of oxygen and carbon dioxide in the breathing gas mixture is essential to assess whether a breathing gas mixture for an airplane pilot meets specific requirements. The monitoring system (100) with the gas measuring device (72) offers possibilities for obtaining indications or estimates (44) in respect to possible contaminations by additional components in the breathing gas supply of an airplane pilot.

Abstract: A monitoring system (100?) is for aeronautical personnel (99), such as aircraft operators, pilots, co-pilots or passengers of airplanes or aircraft, such as aircraft or helicopters of civil or military aviation, passenger aircraft in scheduled or charter traffic, in particular also ultra-fast aircraft. The monitoring system includes a sensor system (60) for a measurement-based monitoring of the gas concentration. The operation of the monitoring system (100?) can be configured by an external input/output unit (450) or an external output unit (460).

Abstract: A process (10), with a computer program, a device (30) and a ventilation system (40) detect a leak in a patient gas module, which suctions and analyzes a continuous sample gas stream from a ventilated patient (20), in a ventilation system for ventilating a patient (20). The process includes a determination (12) of a first time curve of a carbon dioxide concentration in a breathing gas mixture of the patient (20) and the determination (14) of a second time curve of a concentration of another gas in the breathing gas mixture, which gas is different from carbon dioxide. The process (10) further includes a determination (16) of a statistical similarity indicator between the first time curve and the second time curve and the detection (18) of the leak based on the similarity indicator.

Abstract: A monitoring system (100) is provided for flight crew members (99), e.g., aviators, pilots, copilots or passengers, of airplanes or aircraft, e.g., airplanes or helicopters of the civil or military aviation, passenger planes in the scheduled or charter service, especially also ultrafast passenger planes. The monitoring system includes a sensor mechanism and a control unit configured to organize a procedure of a measurement-based monitoring of the gas composition of air, breathing air or breathing gases with the sensor mechanism in an airplane or aircraft, and to control or regulate the procedure. A measurement-based detection of gas concentrations is carried out with the sensor mechanism (60).
