INTRODUCTION As we all have seen the pandemic situation in the world and the sudden oxygen crisis during the second and third waves of COVID- 19, the Oxygen Concentrators came with hope for the patients struggling for oxygen during the crisis. Also, the number of patients with lungs diseases is increasing day by day due to air pollution. So, patients with respiratory problems are also in need of some efficient method of artificial oxygen production. But the oxygen concentrators available in the market were imported from other countries. Along with this, their prices were also sky-high, which makes them difficult to TI - A Review of Portable Oxygen Concentrator JF - International Journal for Research in Applied Science and Engineering Technology DO - 10.22214/ijraset.2022.43615 DA - 2022-05-31 UR - https://www.deepdyve.com/lp/unpaywall/a-review-of-portable-oxygen-concentrator-MVAss5wA2W DP - DeepDyve ER -
