Can a person recover from an anoxic brain injury

Hi, the exact same story is similar to mines only my 18 yr old daughter suffered from asthma attack that led to her cardiac arrest. she passed out as I was requesting EMT to rush her to the hospital I was all frantic I don't think I even started CPR quickly cause I was in shock. The ambulance however showed up 4 minutes after she had went unconscious and began CPR and defribrillation trying to get her heart back started unsuccessful however they were still working on her on the way to emergency, she was trying to get resuscitated for about 50 minutes which at the time they did retrieve her heart beat but she had already endured brain injury, she was experiencing seizuretic spasms and nerve pulses that they had controlled with anti seizure medicatons. after which I was day and night in the hospital hoping and praying for a miracle called my family and church family and around the nations to pray for her. Endlessly waiting for any changes to happen there were none no eye twitching, no reflexes of any kind, no resistance of reflexes etc... she kept having some very weak breathing off the ventilator but it wasnt enough for her to be monitored without it. I watched my baby slowly decline in areas her lungs kept collapsing and she developed pneumonia that they treated with steroids and antibiotics .....sepsis blood infection etc...There came a time all her doctors would tell me her quality of life wasnt gonna improve she may not regain consciousness and so on I was not having it I didnt want to think it I had to have my brother up there with me to translate was said to me just so assurance I was taking it in what they were saying. Time passed by about 2 1/2 wks no change indicated they did neccessary tests and MRI,nuclear EEGs for her for indication of oxygenated blood flow to the brain or to determine brain death. When that was determines by several neurologist I still did not want to accept it but I didnt want her to endure any other unnecessary procedures or test cause my baby was on her way to having a trach and peg tube put in and transported to a long term care facility to give her time,, but she was unable to receive it due to her sodium levels rising so with all the tests that were done the doctors were strongly urging me to start decisions on moving on with the confirmation of brain death. I let my baby go on be at peace and I am hurting but I believe I made the right decision and not just being her mother I didnt want to let her go. My advice to you is you do the same whatever is in your heart that you know your child would want you to do. Im sorry you have to endure this pain and witness everyday but keep faith and only prayer and time will tell. If you believe to give him time then thats what you do. God Bless and praying for you!!!
