Help for the CMS50E oximeter

Those of you with this thing - you set recording for 10 hours, sleep with it, then switch to 'upload' and connect to the computer?

its awfully cute. If i hold my breath, I can't seem to make the spO2 drop....

Well, when you intentionally hold your breath, it seems it does take some time before spO2 drops. How long can you easily hold your breath? I can see the change in the O2 drop. You may want to try a few times, and also there may a be a slight delay, that is, the drop may continue for a few seconds after you resume breathing. What is the sampling time? I forgot if that meter has settable sampling time ...

I don't see a selectable sampling time - just a selectable recording time. Its still frighteningly cute in a pigeon English sort of way.

It's a POS - jmho - total waste for me of good money.

Correct me if I'm wrong but it is FDA approved isn't it?

Believe so but that doesn't change my opinion.

I have had 2 of these - one to replace a faulty one - wish I had kept the first one - it worked though it took 50 pushes on average to turn the blasted thing on.

The second stopped working after a few weeks - won't turn off - won't recognize my finger is in or out. I did get one good night with the second one so that is a plus but only one.

I stand by what I said. POS

It is FDA approved.

And far from a waste of money! I had my wife wear it the first night and she will have a polysomnography shortly. She had 160 Pulse and SpO2 events in a single night with 17 minutes below an 88% SpO2!

And I discovered myself a 20 minutes period with a pulsation at 35 (my normal is 60) this will have to be serioulsly investigated.

This is a waste of money??????

...uh-ho....is this another scientific term??

Just curious.

I know this isn't a scientific term.

As I think about this, if my understanding of POS is correct,
I have heard those two acronyms used together....
sometimes the former to describe the latter.

I could be mistaken though.....just thinking out loud.

Well I am not a scientist - just a damn blasted mathematician in my former existence.

My opinion of the CMS 50E is NOT positive.

I understand your opinion if you have experienced 2 units that do did not work. I think these are made in China

However I read many positive reviews on this forum before i decided to purchase one.

elader now has me wearing mine and holding my breath tonight to see if the levels drop

one other point is that other than the Spo i do not understand what all the other data means or how to interpret it.

I read the reviews too - bought one - I have called this a POS before however.

I have also called the Optilife a POS but many like it.

Hey, isn't that the same language the manual is written in?

I would think the little thing was cuter if the USB cable that came with it worked...I have a message in about a replacement. I'm interested in seeing my oxygen levels when I'm having lots of apneas and hypopneas in a cluster. Haven't gotten to use it yet because of the cable problem.

But I was glad to see that I haven't been able to cause a reading of 88% like I got two doctor's visits ago...I seem to be 95-97% when I have checked during the day...but I haven't tried holding my breath

Ok, I confess.............I too have one of these "cute" little things.......I agree it's cute........My initial impression was it is a FDA approved POS. Admittedly, I do think I could end up with upgrading at some point and may regret not starting out with something a little "higer end." Anyway, using military time, set the recording time to the time you wish to begin your recording........like 2300 for 11:00pm. There's no end time to recording unless your battery goes dead or you sleep more than 24 hours (my dream nap!!!!) I charge mine each night by computer......seems to charge better via computer than outlet.

Using this cute POS, I have actually documented a few apnea events where my heart rate has a very sharp increase in response to decreased sp02. I also find it useful when my asthma is challenged. I used to set my alarm clock every 2 hours to check my peak flows with asthma flares. This week I set the alarm on the oximeter and sleep without worrying about my night time asthma symptoms.

The downside to the little cuty, if you are active during sleep you may knock it off your finger...Saturday morning I woke up gently holding it in my hand......not on the finger,recording but cuddled in my hand. When I downloaded the info, it appeared I had been swaddling it in my hand for about 3 hours.

As for holding your breath and noticing a change in sp02, I've noticed if I breathe deeply I can actually increase my sp02 but it's a little hard to maintain.

So, enjoy your little cute friend.......I'm impressed with mine which I was convinced was a POS at first!!!!
