Portable ergospirometry system for monitoring effort in work tasks or exercise, comprises a mouthpiece or mask, carbon dioxide and oxygen sensors, a processor and telemetry module with a wireless link to a base station

摘要

A portable ergospirometry system attached to a person being tested comprises a mouthpiece or mask (1) for sampling breath, CO2 and O2 sensors (4, 5), a processor (6, 8) for the signals produced and a telemetry module which has a wireless link to a computer-controlled base station. A portable ergospirometry system attached to the person being tested comprises a mouthpiece or mask (1) for breath sampling, CO2 and O2 sensors (4, 5), a processor (6, 8) for the signals produced and a telemetry module which has a wireless link to a computer-controlled base station. A bidirection data and command transmission system is established across this. This allows transmission of coded commands from the computer, converted to audio output giving instructions about behavior or instructions, as well as directly access to information about the use of the measuring device and the progress of the test.
