Oxygen companies in Pakistan have warned that if the supply of oxygen to the industrial sector is not stopped during the current wave of corona, there could be a severe shortage of oxygen cylinders in hospitals. According to Pakistan Oxygen Limited, they normally have one month’s stock, but in the current situation they have to supply oxygen to hospitals on a daily basis. There are five companies in the country that supply oxygen to hospitals. In the current situation, they are giving 100% of their production. Officials say that if corona cases increase in Karachi and Hyderabad, the pressure on oxygen companies will increase.
