    Heart Lung Machine

    Not to de-rail another thread so I'm starting this one. Be kind mods

    Can a heart lung machine tolerate a loss of power for 10 seconds? Does it have batteries? And if so how long are they meant to last? Here is what I have in mind:

    I found a study>
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4680785/

    This information could be of value to the individual who encounters catastrophic institutional power failure or who is transporting a patient on battery power. Perhaps, perfusion teams can use the methods mentioned as a model to test and appreciate the limitations of their own battery power systems.

        Long long time ago, I was a kid in high school and my father was a gas passer at a hospital that did open heart surgery. I recall the roller pump units having a place where a hand crank could be connected to maintain pumping.

        https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4971270/ is a case report; toward the end of surgery the UPS on the unit failed and they hand cranked while finishing things.

          Wow! I hope the machine above has a hand crank feature. And they know how to use it.

          Though I don't think the blood cooler has that option or even a UPS. Oxygenerator has me wondering too.

            Those hand cranks aorta work, they don't need outside human power.

            As for cooling... and oxygenator you sound like you haven't heard of the Einstein-Szilard absorption cooling. Doesn't need electricicity.
            Einstein and colleague hold a patent for this method.
            Look it up.

              Is Einstein-Szilard cooling used here?
