Fred Nightengale update

This has been what I've been looking at and listening to today.Dad had a second spell with his heart during the night and now he is on a heart monitor.Well is/was if all goes well he maybe can come off it late tonight.That is if his rate stays below 100.
He saw the cardiologist today and the first reports have brought some concerns to us.After talking with dad the doctor thinks there is some blockage,however at this time because of his pneumonia he is unable to do any testing.The doctor said his lungs would not take it.So once he is feeling better they can check that out.
He is still extremely weak and having a tough time breathing.His O2 stats stay at around 88-90%, where 100% would be good.And this is with oxygen.His spirits are good and some count that is supposed to be 1 is now in the 20's it was 43 when he was admitted.My neighbor doctor said most times when someone comes in it is high teens low 20's, so we do have a way to go there.
We ask for continued prayers for him and my mom as well.
Thanks in advance.
Mr.Brian
