Dive spirometry testing levels

Patient: Hi all,I am a diver and I went for my yearly dive medical. I passed all tests except the Spiro test. The FEV1/FVC to pass >75%. My results were between 65-72%. Apparently I vary from between normal limits to mild obstruction. I have no history of shortness of breath, asthma and non smoker. Will I be able to dive?

Doctor:
