ALBANY, N.Y., April 29, 2021 /PRNewswire/ -- The current crisis of unavailability of oxygen cylinders in the second wave of COVID-19 in countries such as India has created massive demand for portable oxygen concentrators. The dearth of hospital-grade oxygen due to the vast surge in critically ill COVID-19 patients that require oxygen has led to enormous demand for alternate source portable oxygen concentrators. In its simplest form, an oxygen concentrator is a medical device that collects oxygen from the ambient air. The oxygen concentrator takes in the ambient air, filters it sieve through a sieve, discharges the high concentration of nitrogen back into the air, and utilizes the remaining oxygen.
