Tesla CEO Elon Musk said Thursday that the company has delivered more than 1,100 ventilators to help treat patients infected by the coronavirus to hospitals in the U.S. and Spain.

The shipments included 100 ventilators in Los Angeles County and more than 20 in the Bay Area, according to Musk.

But Los Angeles officials said they received a different machine: bilevel positive airway pressure units, which are not the same as ventilators.

“They have been distributed to hospitals in our system and are being used as intended. These units are used for breathing and airway support, reducing the need for certain patients to be placed on mechanical ventilation,” said Christina Ghaly, director of Los Angeles County Department of Health Services, in a statement.

A county spokeswoman didn’t have immediate information on whether coronavirus patients are using the machines.

Sonoma Valley Hospital said it received six continuous positive airway pressure units, not the six ventilators that Musk said were sent.

The disparity adds to confusion around Tesla’s ventilator commitments, particularly in California.

Musk posted a partial list of ventilator deliveries on Twitter after the Sacramento Bee and CNN reported that Gov. Gavin Newsom’s office said no ventilators had been shipped to California hospitals from the Palo Alto company.

Tesla did not respond to a request for comment on the discrepancy between its list and claims from Newsom’s office.

Musk said Bay Area deliveries also included 10 ventilators to Marin Health and five to Sequoia Hospital in Redwood City. The two hospitals did not immediately respond to requests for confirmation.

Tesla had promised 1,000 ventilators to the state, a commitment announced by Newsom on March 23. Most of the ventilators on Musk’s list were sent to the East Coast, including New York, which has the highest number of coronavirus cases of any state in the country.

Newsom told reporters at a news conference Thursday that he “was not personally aware” of Musk’s list of hospitals.

“I appreciate Elon. I appreciate others that have really stepped up and lent their support and offered even more support beyond what has been made public,” Newsom said. “I look forward to learning more about where they went, and I’m grateful for his support.”

Musk said the ventilator models sent were based on hospital requests. “These were based on direct requests from their ICU wards, with exact specifications of each unit provided before shipment,” Musk said on Twitter, referring to intensive care units.

Last week, Tesla cut pay and furloughed some workers after shutting down its Fremont factory.
