desaturation index

I recently had a sleep test done. It showed I did not have sleep apnea but said that I desaturated "mild in magnitude".  Desaturation Index was 17.1/hr. Is this normal? Should you desaturate at all at night?:

Hello and hope you are doing well.

Oxygen Desaturation Index (ODI) is the number of times per hour of sleep that the blood's oxygen level drops by 3 percent or more from baseline. Normal value is less than 5 desaturations per hour. A value of 17/hr does indicate moderate ODI. Desaturations can occur due sleep disorders like obstructive sleep apnea. But they could also occur due to lung disorders. An elevation in ODI may predispose people to long-term cardiovascular risks, including heart attack, stroke, and memory loss associated with dementia. Please discuss this with your doctor am sure he will provide further assistance.

Hope this helped and do keep us posted.
