Always more PR events than SpO2 events...?

Hi,
I'm waiting for a sleep study (a years wait, so about 10 months left to wait) and I really don't want to wait to figure out what's going on. I've been using the Contec CMS50F.

I can get anywhere between 1 and 50 SpO2 events a night, but always 150+ PR events.
I was diagnosed with bradycardia a few months ago, but the doctors gave me no cause. I do a fair bit of sport, but I'm not professional athlete.

Any thoughts on my results? I'd really appreciate some feedback from people that understand this better than me!



Thank you.

So sorry for you. You must be under a government medical care??

I have bradycardia as well, and am as far as i know, pretty fit and only 32. My cardiologist doesn't see a problem with it.

I use an ASV machine for idiopathic central sleep apnea, and I occasionally wear a pulse ox at night. I stopped wearing it because it was stressing me out. I usually have 1-3 O2 events, and 60 or so pulse events. so similar to you in that i have far, FAR more pulse events.

I am sorry, i don't know how normal or not normal it is. I've asked a few times on here but people really haven't given me much of a response on that one. My doctor is still trying to figure it out.

Good for you. There are too many gadget lovers on here who recommend pulse-oximeters to people who don't need them. If you use Sleepyhead and don't have any lung problems, it is not at all necessary to use a pulse-oximeter. A waste of money, time and worrying.

Hi, yes - I'm in the UK, so on the NHS. I can't afford to pay for a private sleep study (£400 upwards)

I think the criteria needed for reporting a pulse rate change is less than the criteria need for a SpO2 event.
So it wouldn't be unusual for a person to have more pulse rate changes which gets recorded as a PR event.
I forget the specifics but in general pulse rate changes don't necessarily have to be tied to a SpO2 event.

The SPO2 results you provided although not great don't look to bad.
There really is not enough information there without the charts for me to see anything definitive.
If you were to post your charts you might get some more detailed responses.

Sorry to hear about your delay in getting tested, we in the US may soon need to learn to live with the same thing.

Healthy people have variations in their pulse rate. People near death loose those variations and have a much steadier pulse rate.

The oximeter scoring for pulse rate defaults to looking for information on people that are very ill.

A discussion with a cardiologist can help you set your scoring appropriate to your health condition. Once you have proper scoring set up you can then get a better view of what is going on while you sleep.

While many people are content with a one dimensional view of their health, others prefer a multi dimensional view.

The data from the XPAP machines gives you information on air flow. This tells you a lot but is only one dimension. The oximeter adds two more dimensions by measuring oxygen saturation and pulse rate.

Confusion comes from not understanding how all these parameters play together. A little studding and questions asked of those who are trained in their use can provide the education needed to eliminate stress and confusion that may come from viewing things in a multi dimensional format.

My view is that it is my health. I want to know as much as possible about what is going on. If this requires additional study then its back to the books. Air flow data is wonderful and very informative. However there are times when I require a little more information.
