Hello all, My girlfriend is currently working her second year in the field of nursing. I know how hard you all work and how her job can be very exhausting so for Christmas I like to get her some tools that can simplify her job. Last year I got her a Littman and a nice Fossil watch to match her scrubs. This year I remember her mentioning a finger oxygen saturation monitor that also measured a heartbeat. I was just curious what brand of one of these to get because I see them anywhere from 15-200$ and would like to get her a quality device that is of a medical grade. Also if you guys have any other handy devices such as this for gift suggestion let me know so I can hook her up! Thanks for taking the time.
