All good, Dr. Kristo explains my device graphs in a way I can comprehend and answers any questions I have even if some to me may appear stupid'. Dr.Kristo not only thoroughly reviews my Sleep Apnea health progress but reviews my overall health to determine if anything in my general health affects my Apnea or the Apnea might be causing general health issues. Dr. Kristo also keeps my primary Doctor in my health loop which gives me comfort that I am being covered on both ends.
