LOS ANGELES, CA — Tesla founder Elon Musk never delivered the ventilators he had promised to donate to California hospitals, the California governor's office told the Sacramento Bee in a new report out this week. The devices Musk did purchase are not suited to help coronavirus patients. Health officials have warned against this type of ventilator, saying it's not the correct device to treat COVID-19 patients and could further spread the coronavirus, the Bee reports.

Gov. Gavin Newsom had announced in March that Musk had donated more than 1,000 ventilators to help coronavirus patients and said the devices had arrived in Los Angeles. Musk had also tweeted that he had "FDA-approved ventilators" and they could be more available nationwide. Don't miss updates about coronavirus precautions as they are announced.

Instead, Musk had provided BiPAP machines, according to reports, which are used to help treat sleep apnea patients. On Feb. 23 the American Society of Anesthesiologists had issued a guidance warning that CPAP and BPAP machines "may increase the risk of infectious transmission," the Financial Times reports. We have extra FDA-approved ventilators. Will ship to hospitals worldwide within Tesla delivery regions. Device & shipping cost are free. Only requirement is that the vents are needed immediately for patients, not stored in a warehouse. Please me or @Tesla know.
