The test that the nurse will need to check is the OXYGEN SATURATION TEST.
In an healthy lungs, the oxygen saturation level ranges between 95 and 100%, this means that, when red blood cells pass through the lungs 95 to 100% of them is saturated with oxygen. When a lung disease is present, this percentage will be highly reduced. Thus, the oxygen saturation test gives an indication of how efficient the patient's breathing is
