Wow!! "...without ever coming in contact with the patient."

That would be the end of the 1/2 hour standing in the shower to get the glue off. Not to speak of being able to sleep more naturally without all those wires!

Now, the trick would be to get all the sleep centers to give up their expensive traditional equipment and buy infrared.

Interesting, I wish the link was more than 3 paragraphs and suggested exactly what was being done. They note:

"Results of the study by Jayasimha Murthy and his colleagues from the
University of Texas Health Science Center at Houston, the University of
Houston, and Memorial Hermann Sleep Disorders Center in Houston, Tex, showed
that IR-I detected 20 sleep-disordered breathing events, compared with 22
events detected by the nasal-oral thermistor, and 19 events detected by
nasal pressure."

The headline says "Infrared Imaging Shows Promise for Diagnosing OSA" but they don't specially mention that it detects obstructive sleep apneas only all apneas. So the headline would seem to be imprecise.

(Of course some HMO's don't seem to bother testing specifically for OSA. A friend with OSA was given a one channel take home test and then given an un-humidified CPAP--I presume it is compliance data only since the HMO was so cheap about other things but I don't know for sure...)

I would assume that it is just monitoring breath so it couldn't tell the difference. Still possibly useful as a possible addition to the cannula and thermosister approaches.

Unfortunately it seems it is only a substitute for the nasal canula not for all the other sensors. You still can't detect brainwaves and EKGs with it so you'd still need to wash the goo out of your hair (or the goo **and** the leftover gauze in the case of the sleep study I had...)

Right on, ApNoob! My very first thought as well. Pardon me if I don't get too excited after reading the article. There "are" other sleep disorders besides OSA that would be missed if present. Just shows to go you - if the headline sounds like it is too good to be true - it probably is. Too good to be true.

Yeah, yeah, I've been through the educational wringer on good sources - but.... I'm still going to pretend it's amazing news and that I'll never have goo in my hair again : )

Hi,

There is a advanced dynamic-flow imaging system able to detect and display the volume+temperature+density+magnetic+form would revolustionized who we view the world.....kin like detector that sense ghosts.
