NEW THEORY – COMPARED TO ALTITUDE SICKNESS
“We know that mechanical ventilation is not benign,” said Dr. Eddy Fan, an expert on respiratory treatment at Toronto General Hospital. “One of the most important findings in the last few decades is that medical ventilation can worsen lung injury — so we have to be careful how we use it.”
NEW YORK (AP) — 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. vosizneias
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.
The evolving treatments highlight the fact that doctors are still learning the best way to manage a virus that emerged only months ago. They are relying on anecdotal, real-time data amid a crush of patients and shortages of basic supplies.
Mechanical ventilators push oxygen into patients whose lungs are failing. Using the machines involves sedating a patient and sticking a tube into the throat. Deaths in such sick patients are common, no matter the reason they need the breathing help.
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.
Similar reports have 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.
The reason is not clear. It may have to do with what kind of shape the patients were in before they were infected. Or it could be related to how sick they had become by the time they were put on the machines, some experts said.
