In the days of COVID-19, ventilators as artificial breathing machines proved to be the proverbial lifeline. The pandemic seems far from over, even as both the government and the private sector have joined hands and are constantly raising the bar in terms of meeting the growing demand for this lifesaving equipment. What compounds the challenge is that there have been reports of acute medical oxygen shortages in the region, a critical component of the COVID-19 treatment input gas.
The turbine-based ventilators emerge as a powerful alternative from the perspective of manufacturers, medical engineers as well as patients, provided that the majority of healthcare facilities in the country lack an existing centralised air supply system like medical-grade oxygen, compressed air etc. critical for operating an efficient ventilator support system. The government has required, according to media reports, that the ventilator must be turbine or compressor-based for COVID-19 cases, which is an affirmation of the robustness, flexibility and efficiency of turbine-based technology during the current situation for this vital lifesaving system.
How are turbine-based ventilators functioning?
Using the principle of textbook turbine generator technology that includes converting primary agents such as air, water, steam, combustion gases into electrical energy from kinetic energy, turbine ventilators use compressors to create pressurised gas flow. They compress the mixture of ambient air and oxygen coming from the source of oxygen by sucking the ambient air through a filter to create a flow.
