简要总结
20 volunteer test subjects entered into an accuracy study that is designed to validate accuracy of the respiratory rate of the ChroniSense Polso
详细描述
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.

入选标准
- •Subject must have the ability to understand and provide written informed consent
- •Subject is adult over 18 years of age
- •Subject must be willing and able to comply with study procedures and duration
- •Subject is a non-smoker, or a smoker who has refrained from smoking for 1 day.

排除标准
- •Compromised circulation, injury, or physical malformation of fingers, toes, hands, ears or forehead/skull or other sensor sites which would limit the ability to test sites needed for the study. Tattoo in the optical path which would limit the ability to test sites needed for the study. (Note: Certain malformations may still allow subjects to participate if the condition is noted and would not affect the particular sites utilized.)

研究组 & 干预措施
ChroniSense Polso Respiratory Rate
Comparison of respiratory rates in normal subjects as observational with end tidal CO2. No treatment or interventions will be performed
干预措施: ChoniSense Polso (Device)
结局指标
主要结局
Arms accuracy (breaths per minute) of Polso Monitoring System relative to End Tidal Carbon Dioxide monitor-derived respiration rate
时间窗: Through study completion, 1 month average
Accuracy of Polso Monitoring System (DUT) relative to a reference End Tidal Carbon Dioxide monitor-derived respiration rate (REF). Polso reports respiration rate (breaths per minute) directly, at 60 second intervals. End Tidal Carbon Dioxide monitor waveforms will be hand-scored, based on respiration waveform peaks, to derive respiration rate (breaths per minute). The readings from each device will be synchronized to achieve paired simultaneous respiration rates, and aggregated into calculation of a comparative accuracy measure, namely Accuracy root-mean-square (Arms) difference, in breaths per minute, between the Polso (DUT) and the reference (REF) respiratory rate system, for all stable respiratory periods. Acceptance criteria Arms \<3.
