Even under idealconditions, skilled observers cannot consistently detect hypoxemia until theoxygen (O2) saturation is below 80% [1]. Thedifficulty that physicians have in detecting hypoxemia was recently exemplifiedin a study of over 14000 patients being evaluated at the UCLA EmergencyDepartment [2]. Patients were monitored by oximetry butrecordings were given to physicians only after they completed their initialassessment. Changes in diagnostic testing and treatment were most likely at anO2saturation of 89%, and changes were actually less common at lowersaturations, probably because the physicians were able to detect evidence ofhypoxemia without requiring a pulse oximeter.", "distribution": [{"@type": "dcat:Distribution", "description": "Visit the original government dataset for complete information, documentation, and data access.", "downloadURL": "https://www.ncbi.nlm.nih.gov/pmc/articles/PMC137227/", "mediaType": "text/html", "title": "Official Government Data Source"}], "identifier": "https://healthdata.gov/api/views/xgd4-zrqu", "issued": "2025-07-14", "keyword": ["nih", "oxygen-saturation", "pulse-oximetry", "respiratory-monitoring"], "landingPage": "https://healthdata.gov/d/xgd4-zrqu", "modified": "2025-09-29", "programCode": ["009:048"], "publisher": {"@type": "org:Organization", "name": "National Institutes of Health"}, "theme": ["NIH"], "title": "Pulse oximetry"}
