I'm really excited about [0], but as far as I know there is no way to take blood pressure without touching the patient. If someone here could invent it, I could probably provide a test environment for large scale investigations.

Re: studies. I can't say I know the evidence that well, so I wouldn't want to mislead, this isn't my area. A google search for Hourly Rounding reveals lots of articles, but I haven't poked into the underlying data that proves it is a successful strategy (if that exists). I guess I overstated my confidence above.

For blood pressure, our experience was that the staff were perfectly happy to leave a cuff on our daughter's leg, which automatically took a reading every hour (or on demand).

For some patients, with vascular disease for example, the blood pressure cuff can be very painful... (What you describe is usually what we do.)
