Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary purpose of this study is to conduct a Respiratory Rate accuracy validation comparing the Spire Medical Health Tag to a FDA cleared End Tidal Carbon Dioxide monitor Reference Standard (GE Datex-Ohmeda). After IRB approval, a minimum of 20 healthy volunteer test subjects, 18 or older will be entered into this study designed to validate the accuracy of the respiratory rate feature of the Spire Medical Health Tag (Device Under Test). The subjects will be selected to represent a range of body types including small, average, muscular, and large with a range of BMIs. Each subject will be connected to a FDA cleared EtCO2 monitor (GE Datex-Ohmeda) and will be instrumented with a mouthpiece or open system mask that allows for measurement of EtCO2 derived respiratory rate. A range of stable respiratory rates will be elicited from each volunteer test subject with the use of a paced breathing application on a mobile phone. Subjects will also be connected to a 3-lead ECG (GE Datex-Ohmeda) for the purpose of monitoring heart rate and comparing to the pulse rate measurements recorded by the Spire Medical Health Tag. The respiratory rate and pulse rate will be measured simultaneously for the Reference and the Device Under Test.
