Intended Use, Documentation Purpose, Target Group and Safekeeping
System Description
The PowerCube-Ergo is a software-driven, cardio-pulmonary exercise system providing breath-by-breath
measurements of flow, oxygen uptake, carbon dioxide production and optional heart rate.
It measures the human response of increasing exercise with emphasis on the gas exchange and
ventilation parameters. The results of the test can be displayed on a PC and can be printed after the test
if a printer is connected to the PC.
Intended Use
The PowerCube-Ergo is intended for medical applications requiring a non-invasive assessment of the
cardiopulmonary response to exercise or measurement of energy expenditure using indirect calorimetry.
The PowerCube-Ergo is intended to be used on adults and adolescent patients.
The PowerCube-Ergo is intended to be used by trained operators under direct supervision of a licensed
health care practitioner, in hospitals, clinics, physician offices and outreach centres.
The PowerCube-Ergo Ergospirometry module is intended for use with a personal computer system to run
the measurement software, but also as part of a cardiopulmonary exercise testing system.
The PowerCube-Ergo, using LF8, is not meant to be used for any purpose other than those named
herein. If it is used for purposes that do not meet its intended use, this is regarded as an unauthorized
utilization!
