I had my sleep doctor make an interesting comment during my appointment a couple of weeks ago.
As I mentioned, he is a big proponent of the newer machines that are capable of gathering meaningful data for analysis. In addition he is a proponent of the patient taking responsibility for their treatment with guidance from an MD as appropriate. He is aware and occasionally reads the various apnea discussion forums, and he is aware of the sleepyhead software. He thinks all that is good and an educated patient is a good thing.
That said, he mentioned that as much as he likes analyzing data from the machines and making the appropriate adjustments as needed, he also said that he has to guard against becoming overly 'obsessed' with the data alone. He is a sleep doctor and while treating apnea events is of course a large part of his practice, there other things that also contribute to poor sleep. Such as environmental issues (noise, disruptions, mattress, pillow etc), medical issues such as other conditions, illnesses, diseases, and certain OTC and/or prescription meds among other things.
He thought I might be similarly overly focused on the apnea data and that the real goal is to have the patient have good quality sleep throughout the night such that they have good energy throughout the following day.
I thought that was interesting, especially since I tend to want to have hard mathematically quantifiable direct data when making decisions about various things. (not just sleep quality) Life is not always so black and white I suppose.
