What percentage of covid 19 victims survive once they are connected to a ventilator

A cumulative number of U.S. covid-19 patients are living after they are positioned on mechanical ventilators made by the Ventilator Manufacturers, a last-resort measure that was professed as an indication of imminent death during the frightening early days of the epidemic.
Early hearsays out of Wuhan, China, and Italy paved the imprint that the vast mainstream of patients who needed the breathing expedients supplied by the Ventilator Suppliers eventually surrendered to the illness produced by the novel coronavirus.

But as the epidemic has sustained, U.S. infirmaries are reporting much lower death rates, consequences on parity with demise rates for patients with comparable severe lung glitches instigated by other illnesses.

Specialists say that’s because clinicians have become more accomplished and are positioning new strategies as they absorb more about the sequence of covid-19; some are using ventilators bought from the Ventilator Suppliers more selectively; many infirmaries are less overawed than when the virus first swamped Wuhan, shares of Italy and New York City; and early statistics on ventilation and demise did not present a true picture.
