Buccal mucosa sat probes?

  1. At our cardiac care conference this weekend, one of our docs mentioned that we're going to be trialling buccal saturation probes on our cardiacs. She said they can offer a better preductal sat. It's true that it can be hard to get a good sat on the right hand of some of the chubbier cardiacs, but I'm having trouble picturing it. Has anyone used these?

    I thought buccal sat probes were for mixed SvO2 measurements.... did I write it down wrong?

    According to an article I read after the conference, it's arterial. Apparently it works by reflecting the light frequencies off the capillary bed, as opposed to having a facing sensor, like the ones we use now. This is assuming that the patent application I found is for the same/similar product. It can also be used nasally and in the pharynx. It was invented for burn patients.
