holds multiple sessions, timestamped,

That sounds good. Is it rechargeable directly or removable batteries? I think I have to get this. I am deciding that 50D Plus is fine for occasional use, but really isn't the design for every night use.

I would strongly advise getting a pulse oximeter with recording capability. Mine connects via USB. Since I have to have USB connection anyway to upload a night, the USB rechargeable battery is ideal.

Sorry, didn't catch the "+" so didn't realize your unit can record. I have the CMS50F and battery life is about three nights before recharge. But I usually just leave it plugged into the PC USB cable after uploading data.

OK
I am still trying to be sure I understand the differences in the 50F and the 50I; I already bought the wrong one once--want to get it exactly right this time...

diamaunt says the 50I version "holds multiple sessions, timestamped". Does the F do that, or is that the up-step from 50F to 50I?

Your "about three nights" for recharge is same as diamaunt said. I got 2.x (<3) nights on alkalines. Clearly, this thing (all models?) have a pretty heavy current draw and just don't have any significant battery life without recharge.

I could have made my 50D+ work if the rechargables I bought would work in it, but they "die" after just a few hours--not even one whole night.

Could you possibly send me the link by PM for the one u r speaking of as I find getting around Aliexpress a bit difficult when you don't know exactly what you are looking for........i would like to know that I will be buying the right one and not the wrong one ;-)

I seem to recall you or someone mentioning this before as i have purchased from AliExpress before and that it was about $50?

I have seen an ad online in my city but it doesn't seem to offer a brand name but this one is $75
Does it look good or, as I suspect its a cheap Chinese made one that I too could get for $50 but let me know if I am wrong for if so and it IS good, I might buy it just for the sake of expediency as Ali Express I recall took 3 weeks

Quote: New Fingertip Pulse Oximeter SPO2/Heart Rate Monitor FDA/CE

Up for sale is a brand new portable fingertip pulse oximeter. This device displays your blood oxygen saturation levels as well as your heart rate. It is useful for those with sleep apnea, athletes, and those undergoing oxygen therapy. It is also handy for nurses, paramedics and other health professionals.

The device itself is black and has a dual-color OLED display which is very easy to read. Pressing the circular button on the front turns the device on as well as switches between display modes. Easily visible is the oxygen saturation level(%SpO2) and the heartrate(bpm). In addition to this, a small graph at the bottom displays a plethysmograph waveform. This waveform tracks the change in volume of blood with each heart beat- this may be able to indicate a particular heart condition.

Unlike other similar devices on the market. this one runs on two easily accessible AAA batteries which keep the device going for hours. The pictures are of the actual model for sale.
Included in this package:
1- Fingertip Pulse Oximeter (black)
1- Matching silicone case (black)
1- Carrying bag
1- Lanyard
1- Instruction Manual
1- Original Box

if necessary i could send u a link to the ad so as to see the photos being show but when i look i don't see any particular brand name


Thanks In Advance

I didnt see this until now.
Great Point.

I like the USB rechargeable battery idea

Do you have one you could possibly link to so i could then find something similar here in Toronto?


TIA

Now I see mention of yours having USB, I will pass on the $75 version I posted, asking about it.........i want the USB one

BUT ONLY IF THERE IS A WAY TO ACCESS THE RECHARGEABLE BATTERY IF IT DIES.
I DONT WANT TO BUY ONE THAT HAS TO BE THROWN OUT IF THE BATTERY DIES INSIDE AS ITS INACCESSIBLE.......

Mine is "f." Once and once only, in a year and a half it locked up and would not respond in any way at all. I removed some tiny phillips screws and took it apart and rebooted it by monentarily shorting the battery. I don't remember the details of the battery installation, but think it was soldered in because otherwise I would have simply removed it. But no sign of the battery weakening yet.

i have a bunch of USB rechargeable bicycle headlamps and taillights, some used frequently, and none has developed a tired battery yet.

Could not tell if this question has been answered or not?

I have a CMS50F - While it records only ONE session, when you hit 'record'='yes' again, it overwrites the existing session - so you would need to save data after each use, and before the next use.

The software is funky to figure out, but once I understood it, it has worked flawlessly for the last 4+ months that I've owned it. I too leave mine attached to the USB cable until next use (meaning I never even turn mine 'off'.).

I've not read up on the "I" model, but it appears to have some possibly large benefits you might enjoy.

I had an E, which a friend dunked in a glass of water and didn't tell me until too late, and a D+, and a I, from what I read when I was deciding between the F and I, the I is like the F but with multiple session and timestamps. instead of it always starting at 0:00 and counting, the charts actually line up with when you went to sleep...
