Abstract: A process and unit for determining an estimate for a respiratory signal. Measured values are received, and a sum signal is generated, which is a superimposition of the respiratory signal to a cardiogenic signal. The unit detects heartbeats, and a respective heartbeat time period for each. An intermediate signal is calculated by compensating the influence of the cardiac activity on the sum signal. The unit determines an attenuation signal, which is an indicator of the average time curve of the contribution of the cardiogenic signal to the intermediate signal in a predefined reference heartbeat time period. An intermediate signal section is generated as a section of the intermediate signal in a heartbeat time period and intermediate signal sections are mapped to the reference heartbeat time period. The estimated respiratory signal is calculated with the use of the mapped intermediate signal sections and of the attenuation signal.

A filter controller coupled to the characteristic analyzer uses the variability measurement value to define a characteristic of the passband for the first filter and selectively tunes the passband of the first filter according to the defined characteristic. Related apparatus, systems, techniques, and articles are also described.

Abstract: A control system controls fresh gas dispensing for an anesthesia device, with a patient gas-measuring unit, an anesthetic-dispensing unit, a user interface, and a fresh gas regulation unit. With a transition from deactivated assistance mode to activated assistance mode, a processing unit receives a measured signal, a fresh gas signal and an assistance signal and calculates an end tidal anesthetic concentration over time based on a current volume flow, a predefined volume flow and on a current end tidal anesthetic concentration and stores this as a preset curve. A fresh gas correction signal is output upon the determined current end tidal anesthetic concentration leaving a surrounding range of the preset curve. A predefined volume flow curve is changed as a function of the correction signal. The volume flow of fed fresh gas is increased when the surrounding range is undershot and is reduced when the surrounding range is exceeded.
