Slight correction to my earlier post: My mother actually DID have a BP of 60 systolic. The cuff was not misplaced. She was given some meds for her BP, which returned to an acceptable level. Her heart rate did slow a bit but she was still tachycardic when we left.
I'm staying with my dad tonight. He's a wreck. He's one of those stiff-upper-lip types. I've seen him cry exactly three times in my entire lifetime - once when I went away to college, once when his father died, and once today.
