Covid positive patient, was on medication and on 12th day felt difficult breathing. Currently hospitalized and on oxygen supplement from 5 days. She's on piperacillin and meropenem injection along with other vitamins. She's tested covid negative yesterday however she feels difficulty breathing even with oxygen supplement. Liver Function Test is normal. She's very weak. Can someone tell me what is her health condition with the above factors and how long does it take for her oxygen levels to improve and breath without any oxygen supplement. Also is the medication provided to her is right for her condition?
