Abstract:
1. Mobile ergospirometry system, comprising: a portable measurement unit configured to be attached to a subject and incorporating a mouthpiece or mask to collect respiratory gas; a sensor configured to sense a volume or amount of gas and at least one respiratory gas sensor configured to determine at least one of a CO a signal processing unit, a telemetry module, and a computer-assisted base station having a telemetry unit configured to create a wireless connection to the telemetry module; wherein by the telemetry module a bidirectional transmission route to the telemetry unit is set up to transmit data and commands, for which purpose a transmitter and receiver subassembly is provided, so that the base station may communicate online information or requirements for operation of the measurement unit and/or to modify a course of a test, wherein the signal processing unit sends received coded commands to a speech module for conversion and audio output of information, wherein the measurement unit further comprises a heart-rate detector and a multichannel ECG module, such that detection and storage of ergospirometric and cardiological data are performed synchronously by the signal processing unit, and further comprising a memory configured to back up data in the measurement unit, such that, in the memory data, sets are stored in a specified format and comprise data specifically related to each consecutive breath and/or complete sequence of data measured for all or selected parameters during selectable intervals with selectable starting times.
