During my hospitalization for thyroid storm/afib, they had the heart monitor alarm set to too low a heart rate for what I had. It was loudly beeping constantly. I kept asking the nurses to fix it but was given various excuses. Finally I unplugged my connection and told staff that I wasn't going to let them plug me back in until the alarm was fixed. They finally adjusted it. I watched how they did it, though. So the next time someone set the alarm too low, I waited until the coast was clear and I set it back. Good nights of sleep were back!
