REUTERS/Mike Blake/File Picture Elon Musk is being criticized for apparently sending BiPAP machines, not the life-support ventilators most-needed to save coronavirus patients, to a New York hospital. New York City Hospitals thanked Musk and Tesla in a tweet for sending "40 ventilators" to a hospital in Queens, but the photo appears to show a BiPAP machine, which is more commonly used for sleep apnea. Some medical experts have warned that CPAP and BiPAP machines could be harmful in treating coronavirus patients by potentially spreading the disease.
