Pulse oximeters to diagnose CCSVI

Postby WeWillBeatMS » Thu Oct 07, 2010 7:12 pm

If the oxygen saturation rate is supposed to be lower in our heads than the rest of our bodies then why can't this be quantified? The pulse oximeter typically connects to a finger to monitor your heartrate and the percentage of oxygen in the blood with 100% being best and 95% being acceptable. However, there is also an ear adaptor that allows to check the saturation rate at the ear. Why not test with two machines at the same time with one on the earlobe and the other on the finger. If the one on the earlobe has a lower oxygen rate than the one on the finger... then doesn't it seem reasonable to suspect CCSVI?

My guess is that the ear, like much of the face, drains through the external jugulars instead of the internal jugulars. The external jugulars are not blocked and would not show problems.

This sounds like it might work! Though I don't know how well oxygenated the earlobes are vs fingertips; I expect a lot less since I cannot play even the tiniest bit of piano with my earlobes.

But what do I know? I'm sure it's been tried. So you have to have two probes, so you need two pieces of wire. Two amplifiers, even. It's not a big deal... Once the signals are digitized, Haacke and his boys can probably tell a lot from them. But isn't he being railroaded? (In the sense that if he can't find enough normals, he can't say anything about his data set?) I have been told he is not allowed by his IRB to "recruit subjects" on the Internet. Why? Are people who use the Internet somehow suspect? Are they afraid he'll cook up a big scam and collectively foist a distributed Ponzi scheme on them? While it sounds like it would work (for a while), it would be the wrong mark. Too hard to get money out of those guys (or as the drug companies would say, more expensive).

What explanation can they possibly give, other than that he is doing his research too fast and the hospital can't keep up with him?

I tried this and was no difference.

To tell the truth, I doubt these circuits do much besides detect the delta between a pulse and a non-pulse. This is done by differentiation; I wouldn't think it measures oxygenation in any absolute way.

Cece: Thank you, I did not know that. I lost my hearing in my right ear suddenly about 7 yrs ago which in hindsight (before my MS diagnosis 5 yrs ago) my first neuro believes was probably my first major event that indicated MS. All I have left in that ear is tinitus. My wife and I have also noticed that one or both of my ears get really red when I have a headache and feeling dizzy. Also, don't the external jugulars eventually drain into the internal jugulars?

North: You tried it with the earlobe adapter and the finger adapter? Have you tested positive for CCSVI either before or after using the other diagnostic methods?

1eye: There is an infrared light on the pulse-ox fingertip adaptor that I'm pretty sure does actually measure the amount of oxygen in the blood. Maybe someone else can answer for sure though.

Thanks

My friend who can detect Liberation by skin-colour does it primarily with redness. Red ears is definitely red blood, which means *something* is getting to the brain. :-) If it's getting through the BBB too slow is another thing...

If I were designing one, I might think to use infra-red. The ones I've seen use white light, that looks red on your finger, because of all the iron oxide (blood, rust, whatever). Infra-red is invisible. That's why they use it for night-vision.

I had a TV camera that was used looking backward to give you a rear-view, and displayed on the dashboard on an LCD screen.

It was infra-red: useful after dark. But then it started to have a white glow in the middle of the picture. Wouldn't go away until we turned off the rear-window defroster which was nichrome wire embedded in the glass. Problem was, it heated the glass, and heat is infra-red. So to the human eye it was invisible, but to the camera, it was a bright light.

Anyway, the cheap ones probably don't do any oxygen-measuring. Their useful trick is to detect your pulse, and other descriptions may be marketing.

It's a good imaging idea, though.

I guess I'll have to see if my ears redden after I am Liberated. Normally though, red ears are sign that I am catching heck from the missus. Since exploring having this procedure done, I can suggest another simple Liberation detection test - examine the person's wallet.
