X-Message-Number: 27249 Date: Wed, 19 Oct 2005 23:35:55 -0700 (PDT) From: Jeff Davis <> Subject: Circulatory assist for perfusion Cryonetters, While searching the CI website for other info, I came across this article: "Vitrification Protocol used on Dog" by Ben Best http://www.cryonics.org/reports/Dog_Thor.html In the article I note the use of an ACDC Thumper. Clearly, this is a mechanical means to assist in the circulation of fluids in the vasculature -- to help the distribution of perfusate in the various stages of perfusion. I'm wondering if other means have been considered/evaluated. Specifically: "full- or half-leg pneumatic compression devices" (Do a google search on the above term.) For a patent application drawing of the device, here is a US patent issued 1982 http://www.freepatentsonline.com/image-4311135-1.html Then, along the same lines, I had another thought. While it may seem odd, even humorous, I couldn't help but think that a seemingly logical assist to the circulatory process could be achieved simply by strapping the patient to what would be essentially an elevated see saw, and then cycling him/her between head up and head down orientations. One way valves in the veins means that gravity-driven circulation or any other kind for that matter) goes only one way, the right way. Or you could use the pneumatic leg compression and the see saw simultaneously. Very simple. Very non invasive. Just a thought. Best, Jeff Davis "Everything's hard till you know how to do it."
