Need ABG.... you need to get an arterial blood gas test (ABG) to see what your oxygen level is. There are many factors that could render a pulse ox test inaccurate. In order to get an accurate measure of your oxygen level, and to see if the pulse ox test is accurate or not, have your doctor order an ABG. The test can be done as an outpatient. Good luck!!
