Tesla  CEO Elon Musk  said Wednesday that the company’s factory in Buffalo, New York will open “as soon as humanly possible” to produce ventilators that are in short supply due to the spread of the COVID-19 pandemic.

His comments, which were made Wednesday via Twitter, follows previous statements by the CEO outlining plans to either donate ventilators or work to increase production of the critical piece of medical equipment needed for patients who are hospitalized with COVID-19, a respiratory disease caused by coronavirus. COVID-19 attacks the lungs and can cause acute respiratory distress syndrome and pneumonia. And since there is no clinically proven treatment yet, ventilators are relied upon to help people breathe and fight the disease. There are about 160,000 ventilators in the United States and another 12,700 in the National Strategic Supply, the NYT reported.

Last week, Tesla said in a statement it would suspend production at its Fremont, Calif. factory, where it assembles its electric vehicles, and its Buffalo, N.Y gigafactory, except for “those parts and supplies necessary for service, infrastructure and critical supply chains.”

It isn’t clear based on Musk’s statements when the Buffalo plant would reopen or how long it would take to convert a portion of its factory, which is used to produce solar panels. Musk didn’t say if this was part of a possible collaboration with Medtronic .

Medtronic CEO Omar Ishrak told CNBC on Wednesday that it is increasing capacity of its critical care ventilators and partnering with others such as Tesla. He said Medtronic is open sourcing one its lower end ventilators in less acute situations for others to, to make as quickly as they can. These lower end ventilators, which are easier to produce because there are fewer components, can be used as an intermediary step in critical care.

Tesla is one of several automakers, including GM, Ford and FCA that has pledged support to either donate supplies or offer resources to make more ventilators. Earlier this week, Ford said it is working with GE Healthcare to expand production capacity of a ventilator.

GM is working with Ventec Life Systems to help increase production of respiratory care products such as ventilators. Ventec will use GM’s logistics, purchasing and manufacturing expertise to build more ventilators. The companies did not provide further details such as when production might be able to ramp up or how many ventilators would be produced.
