Baltimore health-tech startup Sisu Global Health is developing a way to recycle blood – Baltimore Business Journal

Blood is one of those things Americans take for granted.

Here, when patients are rushed to the hospital after an accident and are losing a lot of blood, we assume the hospital will have units of donated blood ready to hook up when the ambulance arrives. We don’t think about how much each unit of blood costs — yes, it has a price — because we have health insurance that pays the bill.
