Age: 80 Gender: M Height: 5'11" Weight: 160lbs Medication: lots of pain killers, not sure exactly what. Cause of death: complications from pneumonia following heart attack

Dad had a heart attack on Feb 29th. He had a some sort of procedure, I think a stint put in. He seemed to be recovering. I know he talked to mom on the 1st.

March 6th, moved from hospital to skilled nursing center.

March 7th. Dad has chest pains again and is sent back to the hospital. Not sure if it's another heart attack.

March 12th. My oldest sister talks to him, says he seems really confused. He thinks the doctors are trying to kill him and keeps attempting to call 911. Hospital puts a sitter in his room. Apparently his oxygen saturation was in the 70s.

March 13. Dad is diagnosed with pneumonia and the put him on a ventilator. They are suctioning fluids out of his lungs. That evening, nurse leaves message with mom that his left lung has cleared up, but right lung is still rough. Says slow improvement. Plus, heart looks okay. They are keeping him sedated.

March 15th. Dad starts coughing up blood. He gives medical power of attorney to his friend and cuts off all communication with family. Thinks we are all out to get him.

March 16th. They are removing the ventilator to see if he can breath on his own. He becomes combative with hospital staff and tries to walk out.

March 17th. Mom calls and says things have gotten bad with dad. She talked it over with his friend, after discussing it with us, and agree to put on a do not resuscitate order. There is talk of moving him to hospice, but it doesn't matter. He dies around noon.

I didn't get to talk to him during this time. Our whole family has a poor relationship with him, me especially. My sister and I had only talked to him once or twice in the last couple years. So all I'm relaying here is through third parties.

What's bothering me is how quick things turned from Saturday to Monday. Sure, he was being paranoid, but his brain was at least functioning. It just seems awfully fast to go from where he was to, we're pulling him of the ventilator and are letting him pass.

I don't know really what I'm asking. I just want some clarification I guess? Does this all make sense? Is it common for older people to go downhill so quickly?

Thank you for reading.
