Diana, your father's case is really unbearable and the doctor is simply irresponsible. If he is occupied by something more urgent than his patient's life, he should get others to take care of your father. I can't imagine such thing happens in a civilized country. Judging from what you described, your father needs to be attended to asap. Can it be of help if you talk to the senior management of the hospital and get a solution? Time is important.
