Số liệu từ châu Âu, Mỹ và Trung Quốc: Phần lớn bệnh nhân Covid-19 phải dùng đến máy thở đều không qua khỏi

As health officials around the world push to get more ventilators to treat coronavirus patients, some doctors are moving away from using the breathing machines when they can. The reason: Some hospitals have reported unusually high death rates for coronavirus patients on ventilators, and some doctors worry that the machines could be harming certain patients.

Generally speaking, 40% to 50% of patients with severe respiratory distress die while on ventilators, experts say. But 80% or more of coronavirus patients placed on the machines in New York City have died, state and city officials say.

Higher-than-normal death rates also have been reported elsewhere in the U.S., said Dr. Albert Rizzo, the American Lung Association’s chief medical officer. And similar reports have also emerged from China and the United Kingdom. One U.K. report put the figure at 66%. A very small study in Wuhan, the Chinese city where the disease first emerged, said 86% died.
