Dr Wilson comments on a unique closed-loop system that can resuscitate and stabilize trauma patients during transport to a higher level of care.

But we live in the future. We have robots in factories, self-driving cars, autonomous drones. Why not an autonomous trauma doctor? If you are in a life-threatening accident, would you want to be treated… by a robot? If that’s the body, then this is the brain – a ruggedized laptop interpreting a readout of that arterial catheter.
Next, the algorithm gets really interesting. If the patient is still unstable, the computer assesses fluid responsiveness by giving a test dose of fluid and measuring the pulse pressure variation. Greater pulse pressure variation means more fluid responsiveness and the algorithm gives more fluid. Less pulse pressure variation leads the algorithm to uptitrate pressors — in this case,
Once again, we have animals to thank for research advances — in this case, pigs. Fifteen pigs are described in the study. To simulate a severe, hemorrhagic trauma, they were anesthetized and the liver was lacerated. They were then observed passively until the mean arterial pressure had dropped to below 40 mm Hg.
Here, the ReFit system takes over. Autonomously, the system administers two units of blood, followed by fluids, and then norepinephrine or further fluids per the protocol I described earlier. Could an experienced ALS provider do this? Of course. But, as I mentioned before, you aren't always near an experienced ALS provider.
