Saving 4 Patients With Just 1 Ventilator - Now anyone with a walkman or iPod can tell you what they do when there is one music device and two people who want to listen: Plug in a Y-connector. Wouldn’t it be great if you could do the same thing with a medical ventilator? It turns out you can - with some important caveats.

In a catastrophic situation, when there are more patients who require ventilators than there are ventilators available, simple modiﬁcation of the ventilator circuit could help absorb the extra burden.
