Medical expenses for Paul Boynton

My dad Paul had surgery for a pulmonary embolism last year. He was without oxygen to his brain during the surgery for 50 minutes. He was in a coma for months. He finally woke and slowly has started to speak again. He has no movement on his right side. He cannot walk or care for himself in any way. We don't know what the extent of his healing will be . He has reached the limit of his insurance and is in the nursing rehabilitation facility at a cash cost of $150 a day. He has no life insurance either. My dad is a proud Navy vet and one of the kindest people you will ever meet. Please if you can help in any way, he needs it bad.
