Hello Dr. Does inhaling steam for 5 to 10 min results in drop of oxygen level? My mother is recovering from covid-19. She is on low dose of steroid 8mg followed by 4mg methylpred. Also taking blood thinner for 10 days. Her hrct score was 11/25. In recent x ray after 20 days she had b/l hila predominant. Now when she use steamer or inhaler for steam her oxy level drop from 98 to 94 for couple of seconds and return to normal gradually. Any serious issue?
