High inflammation in covid. Concerned!

My mother's CRP was 196 mg/L, ferritin was 475 ng/ml and ESR  was 94. CT scan shows GGOs on lung parenchyma suggesting covid pneumonia. She is on medication - Dexona 8mg, Magnex fortex (03 days course completed), Doxy, Vit D3, ivermectin (03 days course completed), Pan 40, Di Dimer was slightly increased i.e. 0.52 (range 0-0.5) she is taking ecosprin. Her SPo2 levels pre medication was around 88-90. She used to get breathless and cough on slight exertion like walking. Now on 4th day of medication, her SPo2 is around 95-96. Sometimes it goes upto 97. Also made her walk for 6 min and her SPo2 fell from 96 to 94. she has gained strength and doesn't cough that much and is able to walk. On first day of medication, pulse rate fluctuated from 116 to 25 on oximeter within a minute. for past 02 days her pulse fluctuates between 60-70. her o2 saturation increasing is a relief. but I'm concerned regarding high inflammation. will she need hospitalisation. right now she is recovering at home.
