How Does A Heart Lung Machine Work?

For most patients requiring open heart surgery for heart valve repair or a valve replacement procedure, the use of a heart lung machine is critical. The heart lung machine enables the surgeon to stop and cool the heart so that it can be operated on without movement.

In the past, I’ve shared a little bit about heart lung machines on this blog, but I just saw an interesting video at which answers the question that many of us have. That question is “How do heart lung machines work?”

You can click the image above to see the video and learn more about this incredible machine used during open heart surgery.

Keep on tickin!

    While I certainly understand the desire to protect anything that is copywrited, is it not possible for Blausen Medical Communication to make an exception in this case? There is not reason they could not have some really flashy opening and closing acknowledgements with a reminder that the material is available only because they understand the value it would be (is) to so many patients and their families.

    I suspect, Adam, that you have already pursued this. But is there yet a possibility that a request with a large number of signatures from patients and cardiac valve surgeons from all over the country, with maybe some hospital and university administrators thrown in, could tip the scales in the other direction? Their name, in fact, could be displayed every second the video is running. Just a thought. I know how very hard you work for the rest of us! Ginger

    The second sentence in my comment has a double negative. One of the “not”s should be removed. I realize your original post was just shy of six years ago, so this may be rehash. If so, my apologies. I just did not see any other comments.

    Kudos! So much better than seeing a black screen, then Due to the …!

    Typically I still have some questions, but I drive a car and I don’t know how everything in the engine works. However, a machine that work to keep one’s body alive so physicians and surgeons can do their work is a lot closer to home — it’s like having something crawl along side and take over for a time. Great to have even thought of this, let alone make it work!
