What caused my mother's sudden respiratory failure and death after years of osteoarthritis and high blood pressure? - #55796

Respected Sir /Madam, The incidence which is deeply distressing to my heart is the loss of my mother in the year of 2025. She had suffering from osteoarthritis during the last 15-16 years and her one finger of left leg had been bend which overlied the side finger. Occasionally, she took Calpol 650 tablet to get rid of pain and in severe case she took Zerodol P. Also, she had high blood pressure problem. One day at late night she told me that she is feeling respiratory problem and immediately I saw the oxygen level drastically low after checking by oximeter. Without wasting time I shifter her to a nearby nursing home (N. G. Nursing Home at South Kolkata, West Bengal ) but, without administer oxygen support to her, one of them called rmo with his lady assistant were checking blood pressure and oxygen level and on that time my mother was experiencing mouth epilepsy along with foaming causing end of life. One more thing I want to tell you that she was lying on one’s back when she was shifted to the nursing home and they do not change her laying position. Sir / Madam your expert comments on the above executed treatment is earnestly soughted. Thnks and regards, Goutam Kumar Nath
