Functionality of the Pulse Oximeter and Accelerometer Portions of a Novel Wearable Device

A Single Center Study on the Functionality of the Pulse Oximeter and Accelerometer Portions of a Novel Wearable Device

The purpose of this study is to asses the function of an oxygen sensor and the movement sensor in a novel device prototype.

Study Overview

• Status: Completed
• Conditions: Hypoxic Events
• Intervention / Treatment: Device: FDA approved pulse oximeter and DOVE device prototype

Detailed Description

After informing the patient about the study and the potential risk. The patient is asked to wear a prototype of a novel device to sense oxygen levels and movement for the duration of the visit. The day of the enrolment is when the visit will be completed. The patient is required to complete an overnight sleep test (no more than 15 hrs) with the prototype device worn on their index finger and wrist.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Absolute Error of Dove Device Compared to FDA Approved SpO2 Sensor	Dove device will be analyzed against FDA approved SpO2 and Skin tone will be incorporated as a factor of SpO2 function to ensure the device can be reasonably detect hypoxia. At each time point, the difference between the device and the FDA approved standard will be calculated. Mean average error will be used as a single summary statistic, and Bland-Altmann analysis will be used to graphically and numerically represent the limits of agreement.	15 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Questionnaire About Comfort of Device	We assessed the prototypes based on comfort via a 5-point Likert scale and an open-ended qualitative questionnaire. The Likery scale specific to the comfort of the device ranged from 1 (Very uncomfortable) to 5 (very comfortable. Higher values are considered to be better outcomes. Participant will be surveyed with open ended questions for their subjective comfort wearing the DOVE prototype device. The questionnaire will ensure topics such as compliance and comfort or any issues and experiences the subject had with the prototype device.	15-20 minutes depending on the patients questions.
