Evaluation of MABOS for Improved Pulse Oximeter Accuracy in Patients of Color
NCT05995613 · View on ClinicalTrials.gov ↗
Study Summary
Purpose: Investigate the safe wearability and basic functionality - epidermal melanin concentration and blood oxygen estimation - of our developed device: Melanin-Adjusted Blood Oxygen Sensor (MABOS) Participants: Healthy adults 18-65 years of age Procedures (methods): The investigators plan to enroll 12 healthy adult participants for the study. The investigators aim to enroll 4 participants with skin tones associated with those of African descent (Group A), 4 of East Asian descent (Group B), and 4 of European descent (Group C). Additionally, the investigators aim to ensure half of group is male, and the other half female. For the duration of the study, two wearable devices will be placed on the participant: a Nonin PureSat pulse oximeter on a forefinger, and the novel wearable pulse oximeter - MABOS - on the other forefinger. Prior to testing, an Ocean HR2 XR Spectrometer will be used to assess the absorbance of three wavelengths of light - 410, 660, 940 nm - on each patient's inner wrist. Following this, the two devices will be placed on the patient, set up, and calibrated for 10 minutes. During the calibration period, MABOS will be used to measure the same three wavelengths of light utilized by the Ocean HR2 XR Spectrometer (410, 660, and 940 nm). After the calibration period, all participants will be asked to perform the following procedure 5 times as part of the testing period: a deep inhalation lasting no longer than 10 seconds, followed by a slow exhalation lasting no longer than 30 seconds. Between each trial, a five-minute break will be required. For the entire testing period, all two devices will be continuously acquiring data. After this testing period, all two devices will continue taking measurements until 90 minutes have elapsed. Skin integrity will be examined before spectrometer use, after spectrometer use, after the calibration period, every 30 minutes after the start of the testing period, and after the testing period. During the study, if the pa

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05995613
The ClinicalTrials.gov registry entry for NCT05995613 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 9 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of North Carolina, Chapel Hill, which has 725 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Oxygen Saturation appearing as the primary indexed condition, and to 2 interventions — of which MABOS is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05995613 reports 1 study location spanning 1 distinct geographic area — top geographies include North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
