Huffing more offen?

[Dubhead23]

I noticed today that my Argentine Boa has been huffing or blowing air out of her mouth when she exhails. She used to do it every once in a while but I noticed today that it's every couple minutes.

I looked into the possibility of a respiratory infection but I haven't noticed any gargling or open mouth breathing. She's not irritable but she has been staying in her hiding box for the past couple days constantly since I fed her 2 days ago. She usually only stays in there for maybe a day before she's wanting out to visit.

The temps stay about 78-80 in my apartment all the time and durring the day I have a ceramic heat lamp and a UV lamp on and the temp gets to about 85 in the cool side and 90 to 95 in the basking area. I keep the humidity about 70% most of the time. I can't sem to get it any higher but when I finish the new cage it'll have a misting system and no screen on the top to keep the moisture in.

Any help would be great!!!
