Official title
Measurement of Oxygen Saturation in Healthy Human Volunteers Before, During, and After Hyperemic Events Using Multi-Modal Techniques: Spatial Frequency Domain Imaging, Transcutaneous Oxygen Measurement, Pulse Oximeter, and Apple Watch
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Pulse oximeters are common medical devices used to measure blood oxygen saturation (SpO2). These devices are either stand-alone or integrated into physiologic monitoring systems, using 2 wavelengths of light to determine SpO2. With recent advances in technology, Spatial Frequency Domain Imaging (SFDI) uses a range of light wavelengths from red to near-infrared (NIR), and smartphones such as Apple Watch, and transcutaneous oximetry TCOM now have pulse oximetry capabilities. Since it is possible that most patients could utilize this technology, we sought to assess the accuracy, reliability, and usability of these oximeters and compare outcomes. In this study, a cohort of 20 healthy volunteers above the age of 18 including males and females of different skin colors will be assessed at the same site and data will be compared. We aim to provide a set of data that will support the clinical and scientific community and identify more than one reliable skin oxygen measurement modality.
