Clinical Accuracy of Vital Sign Pressure Sensor

Brief summary

This trial seeks to demonstrate clinical accuracy and safety of the integrated V-Sensor when used by the general, healthy adult population interested in measuring their vital signs outside of the clinical setting.

Detailed description

The five vital signs are blood pressure, pulse, respiration, SpO2, and temperature. The user tests two devices mounted on two smartphones. * Temperature: Each user will use the V-sensor mounted on a smartphone to obtain his/her temperature interfaced with a temperature specific 'app'. Before and after the the temperature is obtained using the V-Sensor, the temperature will be obtained using an equivalent thermometer. * Blood Pressure: Each user will test his/her blood pressure using the two sensors mounted on the two phones interfaced with a blood pressure specific 'app'. Before and after each measurement, a reference measurement using a mercury sphygmomanometer will be taken. * Pulse, Respiration, SpO2: Each user will test his/her pulse, respiration, and SpO2 using 2 V-sensors mounted on two separate smartphones interfaced with a Pulse, Respiration, and SpO2 'app'. Before and after each measurement, a reference measurement using equivalent reference devices will be taken.

Masking description

Vital sign results obtained by the device under study are not displayed on phone screen.

Intervention model description

Each participant tests two equivalent vital sign sensors (devices under test) mounted on two different smartphones, one after another to assess accuracy of the device compared to equivalent reference devices.

Design outcomes

Primary

MeasureTime frameDescription
Blood Pressure accuracy to the reference device within the ranges specified by the ISO standard 81060-24 monthsFor systolic and diastolic blood pressures, the mean error of determination of the individual paired determinations of the sphygmomanometer-under-test and the reference sphygmomanometer (Standby Baumanometer) for all participants shall not be greater than 8.0mmHg.
Pulse Rate accuracy to the reference device within the ranges specified by the ISO 80601-2-614 monthsPulse rate accuracy shall be stated as the root-mean-square (rms) difference between paired pulse rate data recorded with the pulse oximeter equipment and with the Nellcor N-PA reference device.
Blood Oxygen accuracy to the reference device within the ranges specified by the ISO 80601-2-61.4 monthsThe SpO2 accuracy shall be stated as a root-mean-square (rms) difference of less than or equal to 4.0% SpO2 over the range of 70% to 100% SaO2
Respiration rate accuracy4 monthsRespiration rate accuracy shall be stated as the root-mean-square (rms) difference between paired respiratory rate data with the Passport Respiration Rate Sensor PS-2133 reference method; target range +/- 10% of participant's respiratory rate
Temperature accuracy to the reference device with the ranges specified by the ISO 80601-2-56 & ATSM 1965 Standard.4 monthsTemperature accuracy shall be stated as the root-mean-square (rms) difference between paired temperatures data recorded with the Exergen Temporal Scanner thermometer. LMD's target is a clinical bias \<= 3.0°C and a clinical repeatability \<= 3.0°C.
