Respiratory Infection - how should I modify my enclosure?

[targciv]

UPDATE (3/8)

I've scheduled a vet appointment for next Tuesday, and in the meantime have been using 3ccs of F10 SC in 500 mL of filtered water in a reptifogger machine, and fogging my snake for 20 min a day for the past 4 days in a 3 qt plastic tub. Today, she also shed her skin. When I handled her later in the day, there were absolutely no breathing issues. I handled her for about 10-15 minutes, and there were no clicking/popping sounds from her body, nor any open mouth breathing. Maybe these breathing issues were because she was going into shed? The open-mouth breathing was what had me convinced it was an RI, but now she seems perfectly fine, curious, actively exploring when I handle her. I'm still planning to take her to the vet on Tuesday, but until then I will continue the F10 treatment. I've also ordered a UTH, thermostat, light dimmer, and digital thermometer, which will all arrive tomorrow, and I'm planning to clean her enclosure then set these new items up the way the sticky on how to set up a glass enclosure directs. Here's hoping for a healthier future for Bella Thank you to everyone for your advice and resources
