In a series of tweets, the NCOC head gave a detailed explanation of the current status of oxygen production, supply and availability in Pakistan for coronavirus patients, the Geo TV reported.
He said the total number of critical care Covid-19 patients on oxygen has reached 5,360.
But Umar said that the "huge increase" has so far been managed because of proactive building capacity of the "entire system from oxygen production to beds."
He then gave an update on the oxygen production increase in Pakistan and the number of oxygen cylinder imported last year.
"Despite there being more than 2,000 additional Covid-19 patients on oxygen vs last June peak, you have not seen the kind (of) tight supply situation we saw last June," Umar wrote.
He said that the government is continuing to build capacity and the NCOC has decided to import 6,000 tonnes of oxygen, 5,000 cylinders and 20 cryogenic tanks.
But Umar warned that the challenge is not over. He reiterated the need to take precautions and follow coronavirus standard operating procedures.
"No system can cope if we allow the disease to spread rapidly. May Allah be with us and protect us," he concluded.
