Defence Research and Development Organisation Chairman G. Satheesh Reddy on March 30 informed that the organisation has developed a mechanism with which one ventilator can be used by multiple patients. "In case, there is a large number of patients and a shortage of ventilators, then we can use one ventilator for multiple patients," said Reddy. Reddy asserted that the ventilator has been tested in a couple of hospitals and a couple of doctors, and it is working fine. "That ventilator has been tested in a couple of hospitals and a couple of doctors, and it is working. Medical experts have given more suggestions to us.
