With normal oxygen masks, only oxygen can be supplied to a patient at no more than 15 liters/minute. If more oxygen is needed then either a high-flow nasal cannula (HFNC) or ICU admission is required. Due to the lack of high-flow nasal cannula and insufficient ICU in Bangladesh, it is not possible to provide high flow oxygen to many of the patients.

Recently, a team of researchers from the Bangladesh University of Engineering and Technology (BUET) has developed a medical oxygen supply technology to meet high-flow oxygen demand without electricity. A device called ‘OxyJet ' has been developed under the leadership of Dr. Taufiq Hasan, Assistant Professor of Biomedical Engineering at BUET. OxyJet mixes atmospheric air and oxygen and generates a flow rate of about 60 liters of high flow oxygen that can be used for patients both in the hospital or at home. 

This innovation can ensure high flow oxygen to patients in general Covid-19 wards and reduce ICU admission.
