Q&A

Would a suit that acts as extra-cardiovascular system allow you to run indefinitely?

+0

Generally, when you run a long distance or do something particularly strenuous, you start breathing heavily because of a decrease of oxygen in your blood. Your gasping and weezing is in an effort to replenish that oxygen that you used up while you were working hard.

So let's say that there exists a suit that contains extra blood and a pump of sorts that adds oxygen and nutrients to your blood. It's basically an external cardiovascular system that constantly filters out your used up blood and replenishes it with the oxygenated and nutrient rich blood. Now you have two systems working at keeping your blood refreshed.

Would this help you run farther distances without feeling winded? What would be the most effective way to incorporate this addition to your current cardiovascular system? (I was thinking lots of needles, but ickkk).
