V-Sensors for Vitals: Assessment of the Accuracy of a Vital Sign Sensor Mounted on a Smartphone

Study Overview
=================
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Blood Pressure accuracy to the reference device within the ranges specified by the ISO standard 81060-2 | For 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. | 4 months | 
| Pulse Rate accuracy to the reference device within the ranges specified by the ISO 80601-2-61 | Pulse 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. | 4 months | 
| Blood Oxygen accuracy to the reference device within the ranges specified by the ISO 80601-2-61. | The 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 | 4 months | 
| Respiration rate accuracy | Respiration 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 | 4 months | 
| Temperature accuracy to the reference device with the ranges specified by the ISO 80601-2-56 & ATSM 1965 Standard. | Temperature 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. | 4 months |
