L&D nurse making life he!L

Update* after my sister (attorney) helped me polish a well worded letter including names/dates/events/ scenarios of specific harassment/ lateral work place violence. We have all meet individually with her or HR and today there with our perspective manages and HR. Basically the meeting was to talk things out. It turned into no mention of the harassment and all about her questioning my competency. Long story short they said we need to work together and get along. Absolute waste of time and the papers the letter was printed up. That’s  ok, I have a paper trail and that’s a start of a start  wink wink 

work at a small community hospital with a very active L&D. RT attend all c-section delivers and respond to any other concerning vaginal delivery or neo needs. We maintain NRP and most Rt on staff (self included) have NICU experience (personally 7 years lvl 3)
I am being tortured my a RN who is out to get me personally. They constantly gossip about my work, sometimes even to my face. All completely fabricated issues. Examples; I applied PPV unnecessarily, on more than 3 occasions complaining that I do not know how to use the T-piece resuscitator (our preferred device at facility), that I have set up the bubble cpap improperly (she was looking at the wrong flow meter). A long long list unfortunately. Yesterday after i attended a delivery in which i had to deliver approx 5 min of cpap to achieve target saturation (with great outcome) she filed an incident report that I improperly set peep on T-piece but charted a different story. My manager is on my side but I fear for my job and my license. What do I do about blatant lies?
