California Gov. Gavin Newsom announced Monday the state would loan 500 ventilators to the national stockpile for use by New York and other states experiencing a crush of coronavirus-related hospitalizations, even as he said the nation’s most populous state needs to find more ventilators of its own. The loan comes after California’s hospitals added more than 3,000 ventilators to their supplies through refurbishing old or broken ones and buying some new. In total, California hospitals have more than 11,000 ventilators, a boost that Newsom said made the state comfortable to share its supply.
