Hello and hope you are doing well.

Understand your predicament.
The normal spirometry values are FVC-80-120% and FEV-80-120%. Also, FEV1/FVC ratio, is a calculated ratio used in the diagnosis of obstructive and restrictive diseases. A diagnosis of COPD is made when the FEV1/FVC ratio is less than 70%.  

Though his spirometry values are below normal, his oxygen saturation is otherwise good. So, please don't worry.

Hope this helped and do keep us posted.
