*Info wanted* wrist oxygen monitor

[spetzal]

Trying to find a consumer OR healthcare grade wrist oxygen monitor that has replacable batteries (AAA or lithium button cell, etc).

Pickings seem slim, and all I can find are consumer devices that have internal non-replacable batteries.

Suggestions?  Already called my cpap supplier, no help there…

If cost is no object, just google "Nonin Wrist Pulse Oximeter".  It takes two AAAs, and will cost you around $1000 with their Nvision software.

Since the newer S11 does not have the Nonin pulse/oximeter capabilities like the S9 and S10, I am trying to find out if ResMed's newer devices will incorporate the Bluetooth version in the future. Specifically the WristOx2 Model 3150 With Bluetooth Low Energy. (Approx $778.00 list) 

Be advised they come in both Bluetooth and USB versions and that Bluetooth might be more compatible with newer, as yet unreleased devices.

wrist isn't very accurate or so I have read

wrist isn't very accurate or so I have read

(1)  With most casual users in non-life threatening applications, you are not looking for scientific precision, but gross readings and trends over a period of time. So accuracy may be less than an issue one might imagine.
(2)  Most pulse oximeters are susceptible to data drop-outs and anomalous artifacts due to sensor motion. Even medical-grade devices. 
(3)  Individuals with heart arrhythmias, including afib, v-tach, PACs, and PVCs can produce wonky pulse readings.
(4)  Nail polish or nail discoloring can also affect O2 readings.
(5)  Many devices have a so-called smart algorithm that automatically adjusts for transient issues.
(6)  You may wish to look at Pulse Oximetry - Nonin and WristOx2® Model 3150 with Bluetooth® Low Energy - Nonin (Look under resources for accuracy data.)

Hope this helps.
