Oximeters with alarms, data logging, and prices less than $300

[Eric Greenwell]

I can't believe how cheap oximeters are getting. Standard fingertip
models are available for $50; fingertip and wrist units with alarms,
data logging, and software are available for less than $300.

$50 Fingertip unit oximeter (no more excuses for using oxygen without one):

$270 Wrist unit with alarms and data logging:

From the website for the above unit:

I already have a wrist unit that I bought several years ago for $500,
but no alarms, no data logging. That $270 unit looks very intriguing.

Amazing how cheap they're getting. Now if some bright young engineer
type would just integrate the wrist oximeter with an oxygen system
like EDS, we'd have a real winner. I bought a pulse oxymeter a couple
years ago (around $250) when I discovered I was getting drowsy at
altitude. What I found really surprised me. I was getting too much
oxygen. I don't have an automatic system, just a flow meter and an
oxymiser canula. I've found through experimentation that I need to
set the flow rate at 1000 to 2000 feet LOWER than my altitude in order
to stay alert. A system that would allow you to set a specific O2
saturation level would compensate for differences in individual
physiologies.

About 3 years ago, I suggested that to Pat McLaughlin of Mountain High.
He said they looked into that, but there were problems, particularly (as
I recall) with the stability of the reading. But, maybe the lowering
cost of the units might inspire another look at them. How about an
oximeter that part of the nasal cannula, reading the blood from the
nostril flesh between the two cannula stubs in your nose?

How did you determine your were getting too much oxygen?

Or, maybe "insufficient CO2" was the real problem, and too much oxygen
flow was removing it?

After getting the oxymeter I checked my % on the ground and found I
was 'normal' at 98%. When I got drowsy at altitude, I showed 99% (max
reading) on the oxymeter. When I reduced the oxy flow and my
saturation dropped to 97 - 98%, I got much better. I've repeated the
experiment dozens times with consistent results.

Yes, but is the logger IGC approved?
