It takes several weeks to re-tool a factory, acquire materials, test the process, start making product, and then deliver said product. You're seeing a lot of these deliveries being made now with PPE which means that actions started being taken weeks, or even over a month ago.
Just because you didn't get daily updates from the factory doesn't mean it wasn't happening.
Millions and millions of masks, gowns, gloves have already been delivered to states over the past few weeks but the demand is just outrageous. As we learned yesterday, one hospital in NY is using 10X their normal PPE each week.
It is not like there is zero inventory and hospitals are out of everything. Inventory exists, and hospitals do have supplies. But the fear is that the absolutely wild increase in usage/demand is still outpacing even much higher supply levels. This is forcing hospital admins to require employees to re-use masks or to preserve PPE in other ways. The hospital isn't out but the admins are AFRAID they would be out if they didn't preserve.
The focus on GM is probably a bit silly since they won't make a dent in ventilator supplies until after the peak has already hit. Our stockpile, increased production from existing suppliers, and smarter national distribution will be the key to having the right amount of ventilators in the right places at the right time. I don't foresee a ventilator shortage if we use our existing supplies in smart ways. NY still has thousands of ventilators in their stockpile yet I hear stories of hospitals worried they will run out today/tomorrow. That isn't a supply issue, that is a distribution issue. Having more supply won't fix that.
