Tesla, along with Ford and GM, have promised to donate or build ventilators, and CEO Elon Musk said recently that the New York factory could reopen soon to produce ventilators. The company recently donated 1,000 ventilators, though critics said that the non-invasive models were the wrong kind. That’s because critical COVID-19 patients need invasive ventilators that can inflate a patient’s lungs with air via intubation.

However, New York governor Andrew Cuomo said that the so-called BiPAP non-invasive ventilators could be converted into the right type to help offset the “burn rate” of critical invasive ventilators. Elon Musk subsequently tweeted that “all hospitals were given exact specifications of [the donated models] & all confirmed they would be critical.” He added that Tesla has now started delivering critical intratracheal ventilators from Medtronic for “worst case situations.”
