Friday PM

We've been sitting with our dad throughout the day. About an hour ago he all of a sudden became really red and broke out in a sweat. The nurse checked his vitals and everything was of normal range. He has been really in and out of it all day. One second he is fully awake and alert, the next he is groggy and/or asleep. Hmmmmm?? We are not sure what to think. We will keep bugging the nurses and doctors until we have answers.
