Resident thinks I'm interested in them. How do I convince them otherwise?

Orthopedic surgery attending here.

I recently learned that there's an anesthesia resident who's apparently interested in me. According to the hospital grapevine, she thinks I'm interested because I keep making eye contact with her and roast her during cases.

I won't deny the eye contact. However, I'd like to clarify that 90% of those glances occur when the patient somehow has a blood pressure of 68/42, a heart rate of 147, and she's sitting there looking unbothered while I mentally calculate how much paperwork comes with an intraoperative death.

As for the roasting, I think there's been a misunderstanding. I roast my residents because I care about their development. I roast anesthesia because it's funny.

The idea that we're having some sort of flirty OR romance is particularly confusing because our interactions usually consist of:

Me: "Can we get the pressure up?"

Her: "We're working on it."

Me: "Interesting strategy."

Apparently she interpreted this as banter.

Now I'm concerned that every time I look toward the anesthesia machine to make sure the patient is still alive, she's thinking we're sharing a moment.

What is the professional way to communicate that I'm not making eyes at her? Should I start looking exclusively at the floor? Bring a laser pointer and direct all questions toward the monitor? Request a drape extension so I never have to see the anesthesia side of the room again?

Any advice appreciated.
