Do snakes huff and puff? Not hiss, but puff? Like, ... angry sigh?

Last night my husband had Yzma around his neck but kept one hand gripped around her middle because sometimes she squeezes. She kept her mouth closed, so wasn't hissing, but boy, was she doing a lot of pissed off puffing!! Loud puffs in is ear! I came over and heard them. Once he moved his hand away and she settled in nice and warm, she stopped.

I had originally feared an RI because there was so much puffing, but, do they huff a lot if upset?

Her cold side ranges 78 to 81 and hot side 88 to 91 and humidity between 50 and 70 percent (no condensation in tank so she's getting air flow even with the top taped off except where her lamps sit.) Occasionally we may catch the cold side at 76 so we turn up her lamp, but its rare. And the humidity is usually closer to high 50s low 60s but does spike and drop. We only hold her maybe twice a week for 15 to 30 mins, but the rest of the house is cool - snake room is toasty. She perks up when we bring her back into her warm room after holding her.

Should I worry about an RI or was she just cranky?
