w If the examiner is concerned about the pulmonary stability or safety of the driver, a pulmonary function test may be required.
w If the PFT is abnormal with FEV1 < 65% predicted and FEV1/FVC ratio < 65% (obstructive pattern) or FVC <60% (restrictive pattern) then a pulse oximetry test will be performed.
w If pulse oximetry is less than 92% then an Arterial Blood Gas (ABG) will be obtained.
w If the ABG shows a PaO2 <65 mmHg and or a PzCO2 >45mm Hg then you will not qualify for certification.
