My brother seems to have died of respiratory circulatory failure I am very suspicious of the carer who looked after him, in fact he has been arrested  is it possible that respiratory circulatory failure can be caused by a pillow being out over his airways?  thanks
Hi, Yes, there is a possibility. Still, need to rule out other causes related to pathology of lungs and heart. Hope I have answered your query. Let me know if I can assist you further.
