> Dr. Greg Neyman, a resident a year ahead of me in residency, had done a study on the use of ventilators in a mass casualty situation. What he came up with was that if you have two people who are roughly the same size and tidal volume, you can just double the tidal volume and stick them on Y tubing on one ventilator.

This technique was later applied during the COVID-19 pandemic, when ventilators were in high demand and short supply.
