Death due to Brain Stroke & COPD

[Tiku]

My father has COPD and one month ago due to brain stroke ( stroke coverd his right side) he got paralised in LHS. suddnly his COPD attack increses and he put in to artificial ventilation. but within 32 hours he got out of it. After that he live nicely but every 2-3 days he got spazum and needed to gave oxygen supply with bipap. Doctor (Chest Specialist) was always telling that his lungs are weak but not that much which causes frequent spazum. After few days he was absolutely okay but still have paralises in LHS and we were going to take discharged from the hospital on the next day with wheel chair. But on the same day he felt Acute COPD attack and he tooked on to artificial ventilation. But next day neurologist said that "His Brain is dead, and he won't be rebound".  On the base of this history I want to ask..
1) What happend to him when he is recovering?
2) What could be the main reason of his death?
3) When all the reports are normal just have Stroke impact in LHS, which was also improving then what actully happed, and he dead?

Thanks a lot Mam, Actually I am not satisfied with the doctors' statement. But When Neurologist said he wan't be rebound and artificial respiration was removed his heart had stoped working in few minutes... But still I can not imagine about the cause of his death. when his CT scan of Lungs was normal and there was no cardiac malfunction (because Angiography was done and was normal, there was some uneven blockage but not to put stante) then what was the reason for Stroke - Should it be due to COPD? or due to COPD?  I'll go through the link which you suggest me.. Once again Thanks a Lot..

One more question I wanted to ask you,
My mother has elergic Asthma, what should we do as a Precaution? She has weather Elergy.
Please Guide me.

Take care
Bye

Hello Tiku,
I understand your concern and empathsise.
The following information on the brain detah would be of great help. Brain dead does not mean the bodily death. Miracles do happen in this world.
Definition of brain dead means as a response to the ability to resuscitate individuals and mechanically keep the heart and lungs working. In simple terms, brain death is the irreversible end of all brain activity (including involuntary activity necessary to sustain life) due to total necrosis of the cerebral neurons following loss of blood flow and oxygenation. It should not be confused with a persistent vegetative state. brain-dead individual has no clinical evidence of brain function upon physical examination. This includes no response to pain and no cranial nerve reflexes. Reflexes include pupillary response (fixed pupils), oculocephalic reflex, corneal reflex, no response to the caloric reflex test and no spontaneous respirations.
