Why or why not?<\/strong><\/li>\r\n<\/ol>\r\nAnswer: yes it might be appropriate. For persons with COPD check prescribers orders for target range SpO2. Generally persons with COPD target ranges are approx. 88-92% because of the lung changes associated with the disease<\/em>\r\n\r\n \r\n\r\nSource: British Thoracic Society Emergency Oxygen Guideline Development Group.
