Depth of Anesthesia Reality Check

Wednesday, January 13th, 2010

I think this is the first time I've ever seen MedGadget express such a strong opinion about a technology.

Masimo Invests in Anesthesia Awareness Technology. Good Move? We Don't Think So doesn't pull any punches.

What's interesting to me is that SEDLine was Hospira's brain function monitoring business (see here).  Hospira bought the technology from a Boston-based company called Physiometrix in 2005.

Back in my EEG days I had a chance to work with Physiometrix. We interfaced with their EEG front-end hardware in an attempt to develop an OEM relationship.  At the time, they were using essentially the same Bispectral index (BIS) technology as Aspect Medical.  The only other thing I remember is that they were also using QNX.

MedGadget's skepticism seems well founded. On the other hand, the people at Masimo (a couple of which I know) aren't dummies . They may know something the rest of us don't.
