20 volunteer test subjects entered into an accuracy study that is designed to validate accuracy of the respiratory rate of the ChroniSense Polso.~A range of stable respiratory rates were elicited from each volunteer test subject. The rates will be approximately 5, 10, 15, 20, 25, 30, 35, 40 and 45 breaths per minute; with some natural variation from these exact numbers.~Each subject was instrumented with an open system mask that allows for measurement of the end tidal carbon dioxide (EtCO2) respiratory rate and tidal volume. The EtCO2 monitor was used as the Accuracy Reference Device (Reference) in this study.
