Demand for oxygen beds up Updated: Updated: We see more positive patients with lung involvement: doctors Share Article Madurai There has been a rise in demand for oxygen support for COVID-19 positive patients during the second wave as compared to last year. Data obtained from the health department shows that nearly 40% beds in government hospitals and 28% beds in private hospitals with oxygen support have been occupied as at 8 p.m. on April 26. Doctors say that they could see more positive patients with lung involvement due to the coronavirus infections. This increases the requirement for oxygen support, they say. Government Rajaji Hospital Dean J. Sangumani said that there was sufficient quantum of oxygen available at the hospital. Last year, initially the hospital had an oxygen capacity of 6,000 litres. It was increased to 20,000 litres last year. "Currently, the hospital has the capacity to store up to 26,000 litres of oxygen," he said.
