Yay another reason to avoid brick and mortar and expand my general isolation.

And there's no bypass machine small enough to tote around. These things, fully configured are like 48x36x70 inches and weigh a couple hundred lbs and require electric power. They also require an oxygen feed as they not only circulate but oxygenate your blood. They also require a trained specialist to operate..known as a perfusionist. They are called heart/lung bypass machines. I know this from having heart surgery but also because I am a medical planner and have done several cardiac surgery suites.

I would offer to this that staying on a bypass isn't optimal. After having a valve repaired I developed migraine. Cardiologist said it happens to patients who stay on them for a long time and my case was long. Others counter this so who knows but I didn't have them before and I still get them. I know, I know..this doesn't prove anything but I'm sharing anyway.
