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. The report states there is small airway obstruction, which could be due to Asthma, hence you have been initiated on Ventolin. You may need a follow up spirometry, to see for changes in the lung function tests. You can also do steam inhalations prior to your meals. This helps to loosen up and bring out the secretions.
