Senstream vs Oxyg'App

RESEARCH RING: LAB GRADE PHYSIOLOGICAL DATA ACQUISITION PLEASE NOTE:  The Senstream Researcher Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. The app is designed to record physiological signal data, but not to make medical decisions. Multi-Sensor: Electrodermal activity (EDA, aka GSR), ECG, PPG, temperature and motion, captured from a single, user friendly device with long battery life. Electrodermal Data: Our initial product is the first ring form factor device that captures electrodermal activity with lab quality, enabling new types of research. ECG and/or Pulse: Capture electrocardiograph (ECG) and/or photoplethysmograph (PPG) data, depending on the specific needs of a study or application. Temperature and Motion: Capture temperature data from the finger, and contextualize physiological data with motion data captured by the Research Ring. Mobile and Cloud Apps: Start capturing data with just a ring and mobile app, which seamlessly connects to the cloud. BIOPAC integration offers powerful tools. Bold Vision: The Senstream roadmap, supported by a rich patent portfolio, leverages the convenience and unique physiology of the finger. Stay tuned!

Oxygen management should rely on oxygenation targets, with minimal and maximal boundaries to avoid both hypoxemia and hyperoxemia. Oxygen titration using targets based on arterial saturation (SaO2) are not feasible due to discontinuous measurements of this parameter that requires an arterial blood gas analysis. The oxygen support must be titrated based on SpO2 that allows continuous measurements of patient oxygenation, even though this technology has limitations and needs improvement. We may hope for a major technological evolution as the main working principles of this technology, which are more than 50 years old, have not changed appreciably. Waiting for this improvement in pulse oximetry technology, clinicians should tread carefully and apply algorithms to correct for these deficiencies. Whatever the clinician thinks is the appropriate oxygenation target, this "optimal SaO2" target needs to be corrected when utilizing the SpO2 for the titration based on skin pigmentation and oximeter brand. It has become increasingly apparent that the SpO2 target cannot simply be the SaO2 target! To facilitate the quest of the optimal SpO2 targets and to promote a more homogeneous management of patients’ oxygenation regardless of skin pigmentation or monitoring device of oxygenation there are several potential solutions. We believe that one SpO2 target does not fit all patients and that further clinical trials and clinical guidelines should use corrected SpO2 targets rather than universal targets for all patients. Consequently, clinicians should first define a SaO2 target relative to the patient under respiratory support and then apply corrections for the mean bias related to the skin pigmentation and to the oximeter used to get the corrected SpO2.
