A mobile ergospirometry system including a portable measurement unit that can
be
attached to a subject and that incorporates a mouthpiece or mask to collect respiratory
gas, a sensor for the volume or amount of gas as well as sensors to determine the
CO2/O2 concentration in the respiratory gas, a signal processing
unit, and a telemetry module. The system further includes a computer-assisted base
station having a telemetry unit to create a wireless connection to the telemetry
module. In the system a bidirectional transmission route to the telemetry unit
is set up by the telemetry module to transmit data and commands, for which purpose
a transmitter and receiver subassembly is provided in each case, so that from the
base station it is possible to communicate to the subject online information or
requirements for operation of the measurement unit and/or the progress of the test.
The signal processing unit sends coded commands that it receives to a speech module
for the conversion and audio output of instructions as to behavior, explanations,
or similar information.
