A process device and system for measuring flow parameters in flowing gases is provided in which a device for flow-induced sound generation is in the area of the flow to be measured. A measurement of the frequency and/or the level of the sounds generated is made during the flow to be measured as acoustic parameters. A determination is made as to the flow parameters to be measured by processing the measured acoustic parameters. The process makes possible, in particular, the measurement of the volume flows during respiration near the patient.

Process and device for measuring flow parameters

An open patient care unit with a bed (), with inner and outer air discharge channels () extending around the bed () at least over some sections, and with at least one air exhaust or a purgative suction unit () arranged above the bed (), wherein the air discharge channels () are directed such that they converge toward the air exhaust or purgative suction unit (), and wherein ambient air delivered via a first fan () is discharged from the outer air discharge channels (), and air, which is conditioned in terms of humidity and/or temperature and is delivered via a second fan () from the air exhaust or purgative suction unit (), is discharged from the inner air discharge channels (), has the essential advantage that a hood, which is used in incubators, is not used at all, so that switching over between different operating states is not necessary, and cooling down of the patient is thus avoided, but good access is at the same time ensured for the care providers.
