More than 100 ventilators supplied under PM CARES fund in Jammu and Kashmir have been found defective and "unfit for critical care" on trial runs. The ventilators supplied to the Government Medical College, Srinagar, were manufactured by three different companies. According to doctors, a trial run is not done on every machine. For every company, tests are conducted on a few machines to check the quality. The government said an inquiry will be ordered to fix the responsibility.
