OMG. These are the symptoms my husband had after 28 days in the hospital.He died August 28th, 2017. He started experiencing low oxygen levels after being home for two weeks from a routine hip surgery. They tested him for everything between blood tests and x-rays. Even the autopsy showed– acute respiratory distress syndrome. This is absolutely horrible. But how would I KNOW.? Isn't that what a team of 12 cardiologists, 12 , pulmonists, , onconoligsts, hematologists and diabetes team should have suspected? I am in shock right now.
