85 year old covid patient / tracheostomy

So my grandmother suffered a brain hemorrhage around 8 months back and during the treatment she caught Pneumonia due to which doctors had to put her on tracheostomy support also she suffered paralysis due to this. From last 8 months her condition improved hugely but recently due to covid increase my mom caught covid and she got infected as well. Her E target value is 28, RdRp target value is 28 and RP target value is 25. Major problem she has been facing from last 4-5 days is one of caugh which has increased too much and oxygen cylinder which we had to use 3-4 times in a month now is more or less on continious which is in between 1-6 range. I have attached her current prescription for your reference. Help on what medicines should we give her will be very very helpful.
