p.s. I've forgotten to mention the low blood pressure issue. Chuck has orthostatic hypotension ... his blood pressure drops when he sits up for physical therapy ... or any other reason (like an attempted escape from the hospital). We are trying several things. First, he got the compression stockings. That did not work. Now we are trying the pnuematic pressure device (sleeves on the legs that squeeze his legs intermittently). Please include a nice, stable blood pressure in your prayers.
