How significant is VS overall?

Post by calgurl@hrt » Fri Aug 20, 2010 7:38 pm

Hi all,
When I checked my reports yesterday (and then this morning), it shows that my Vibratory Snoring is way higher than it has been in the past. IE: it generally runs in the 20's/30's but Wed and last night they were in the 90's. I talked with the Physician's assistant that I see at the sleep MD's office and he said it's probably from allergies and prescribed a nasal steroid (flonase, I think).
My question: is this significant for my nightly cpap therapy? If I have higher VS's, does this mean I'm not getting good therapy that night? What does VS actually mean? I felt like crap all day today, really really tired (and cranky, according to my husband ) but I'm not sure if the higher VS and mood/energy today are related.
Thanks so much!

Deb,

Some folks say that any snoring has the potential to disrupt your sleep. I took that advice and attempted to suppress the snores. I found that just a tiny upward tweak in my pressure knocked them out. I have to admit that in my case, I don't think that I felt any different without the snores. Then again, I really don't want to snore, so it was still a net positive. I think the decision is based on (1) how you feel, (2) if you have a reason to prevent the snores, and (3) can you do it without messing up your therapy or introducing new problems.

If you are having allergies or are getting sick, you might not know if your tiredness and mood were related to not feeling well, or if it was a bad night on the CPAP machine. Perhaps you need to give it a few days to see what is happening as far as the allergies or to see if you get sick.

Maybe the titration guidelines give some hint:
4.2.2.5 CPAP may be increased (according to the criterion in Recommendation 4.2.2.1) if at least 1 min of loud or unambiguous snoring is observed for patients <12 years or if at least 3 min of loud or unambiguous snoring are observed for patients ≥12 years (Consensus).
This recommendation is based on consensus agreement by the PAP Titration Task Force. The utility of titrating CPAP to eliminate
snoring was demonstrated in a limited study of non-apneic patients. Although a minority of these patients accepted CPAP use and their subsequent CPAP adherence was poor, 73% of these patients nevertheless reported improvement in their subjective
daytime sleepiness after using CPAP for a six-month period.

That seems to be based on this:
