just talked to mom, and she said that dad still has fluid in his lungs. another issue is that his physical therapist is telling him he needs to get up and walk around a little bit to get blood circulating, but as soon as he does that, his nurses come running in the room saying WTF ARE YOU DOING?!!? they're watching his heart rate skyrocket anytime he tries to elevate himself. so please, keep the prayers coming. again, its greatly appreciated!
