Amid a serious oxygen crisis in the national capital, 25 "sickest" COVID-19 patients died at Sir Ganga Ram Hospital here in the last 24 hours, officials said on Friday.
Sources said "low pressure oxygen" could be the likely cause for the deaths.
A central government source said the SGRH has "sufficient balance of oxygen and a tanker has reached the hospital, which will fill up the storage capacity".
The tanker reached the hospital around 9.20 am. The stock can last up to five hours, depending on the consumption, an official at Sir Ganga Ram Hospital said.
In a letter to Union Health Minister Harsh Vardhan, Deputy Chief Minister Manish Sisodia said six private hospitals had exhausted their oxygen supply by Thursday evening.
As patients and their family members waited outside hospitals, hoping to get a bed, Delhi Health Minister Satyendar Jain on Thursday had said beds would be increased in large numbers once the oxygen crisis was resolved.
A government doctor said hospitals in Delhi are wary of admitting more patients amid a serious shortage of oxygen in the city.
