Detailed explanation-1: -For oxygen produced by the air-liquefaction process, the International Pharmacopoeia, defines the requirements of medical-use oxygen. Currently, oxygen must contains not less than 99.5% v/v of O2.
Detailed explanation-2: -A supply of 60% oxygen with 40% nitrogen should be acceptable for most clinical purposes, since usually only low dosages of oxygen are required. The gas may be provided by means of an oxygen concentrator (Rimer-Birlec), which is a compact, transportable, electrically operated apparatus capable of providing 28 l./min.
Detailed explanation-3: -Oxygen is an essential medicine, and despite being vital for the effective treatment of hospitalised COVID-19 patients, access in LMICs is limited due to cost, infrastructure and logistical barriers. Health facilities often cannot access the oxygen they require, resulting in the unnecessary loss of lives.
