The Problem's Nature

My father smoked for forty years but quit forty years ago. Among the challenges confronting him, his anxiety causing him to breathe too rapidly seems to be the most perplexing. He can not be weaned off the ventilator because he panics and hyperventilates. He is then sedated which makes it that much harder to breathe on his own. He is obviously still quite critically ill and he and we need and thank you for your continuing prayers.
