Community
The Open Oximetry Project was created to improve the safety and accuracy of pulse oximeters in all populations. We recognize that many teams and sectors around the world are working on these issues and hope to build a Collaborators' Community of stakeholders from diverse disciplines, geographies, industries, viewpoints and populations, to prevent duplication of efforts, share knowledge, and accelerate progress.

Job opportunities
Health Disparities Data Analyst
The UCSF Department of Anesthesia, Hypoxia Lab (hypoxialab.org) and the Center for Health Equity in Surgery and Anesthesia (chesa.ucsf.edu) are seeking a full-time Data Analyst for a period of 12 months. The Data Analyst will support several studies in the hospital and human research laboratory to characterize the potential impact of skin pigment on accuracy of pulse oximetry and other medical diagnostic and health care wearables that may be affected. We are collecting vast amounts of diagnostics data, some using novel data collection methods. As part of the project we will be setting up robust data collection systems in the lab and the hospital settings as well as creating and managing an open access data repository for diagnostics device data. For more information on the position and to apply, visit the UCSF job portal.
The UCSF Department of Anesthesia, Hypoxia Lab (hypoxialab.org) and the Center for Health Equity in Surgery and Anesthesia (chesa.ucsf.edu) are seeking a full-time Clinical Research Coordinator. We are undertaking prospective studies in the hospital and research laboratory settings to characterize the potential impact of skin pigment on accuracy or pulse oximetry. The Clinical Research Coordinator will carry out the needed tasks as part of ongoing and future clinical and translational research projects to better understand bias in pulse oximetry in vulnerable populations in the San Francisco Bay Area. For more information on the position and to apply, visit the UCSF job portal.
The UCSF Department of Anesthesia, Hypoxia Lab (hypoxialab.org) and the Center for Health Equity in Surgery and Anesthesia (chesa.ucsf.edu) are seeking a motivated postdoctoral researcher to work on a funded project at the UCSF Hypoxia Lab (hypoxialab.org) related to improving pulse oximeter performance in certain clinical scenarios including dark skin pigment and low perfusion states. Our lab has done seminal work to help identify limitations in current oximetry technology, and we are now embarking to solve these challenges. The Postdoctoral researcher will work closely with our multidisciplinary team to develop new validation protocols for use on human study subject testing, develop new in vitro testing devices to validate existing and new technologies, and collect data on performance of new and emerging clinical devices as part of the OpenOximetry.org project. This is a 1 year postdoctoral program, with possibility of extension for an additional year. To apply, please send a CV, cover letter, one manuscript (published or unpublishsed), and the contact information for 2 references to fekir.negussie AT ucsf.edu
