Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- and am glad to address to your query here.

The information given here is insufficient to make a guess of what exactly happened.
The cause for admission can be anything from respiratory infection, cardiac ischaemia, advanced COPD and type 2 respiratory failure, abolition of hypoxic drive of respiration and so on. The list is long..

The cause for cessation of respiration and heart can not be pinpointed with this little information.
Please talk to the treating doctor to know the reason.

Would be glad to help if you could give detailed description of all the symptoms here.

Thank you and Good luck!
