Re: SATS: How low is too low?
In my experience with Raynaud's, sats are not looked at, since Raynaud's causes the temporary cyanosis (the blue or purple phase) that drops the sats. No oxygen due to the vasospasms is part of the problem that is Raynaud's, therefore the sats just aren't that useful in that setting. Of course, I'm just a patient. You don't say what's being affected by your Raynaud's, but there are some things that you can do to help prevent attacks. Dressing in layers to help maintain body warmth can be helpful. Relieving stress can be very helpful as that in and of itself can bring on attacks. Those little chemical handwarmers are great for your hands and feet. I myself am a firm believer in wool socks. I bring mittens to the grocery store to use in the coolers and frozen food sections and even wear gloves to the office if the air conditioning is a bit much in the middle of summer. I try never to touch cold things with my bare hands and am very careful about anything that can inhibit circulation, such as tight ribbing around socks and gloves. In severe cases, there are medications that can be prescribed as well, both systemic and topical. I am currently on one of the calcium channel blockers for Raynaud's myself. Bottom line is avoiding attacks if you can obviously helps the most and using your pulse oximeter just doesn't really give you anything useful, given the nature of Raynaud's. I certainly can sympathize with you as I am going into the cold dreary damp time of year, just before the snows of winter really let fly.
