Macy-Pan ST2200 FAQ
Why choose a sitting chamber over a lying chamber?
Sitting chambers work for users who can't lie flat comfortably for 60–90 minutes — older adults, anyone with back or hip issues, people with mobility concerns. They also let you stay productive during sessions (reading, email, calls, content) instead of just lying still. The trade-off: sitting chambers are slightly smaller than lying versions, so tall users (6'2"+) should check interior dimensions first.
1.3 vs 1.5 ATA — what's the practical difference?
At 1.3 ATA you're breathing oxygen at roughly 30% greater pressure than sea level — appropriate for sleep, general wellness, and mild recovery. At 1.5 ATA the pressure delivers more dissolved oxygen per session, which users running athletic recovery or inflammation protocols prefer. The ST2200 adjusts between both, so you can start at 1.3 ATA and move to 1.5 ATA as you acclimate.
Is the ST2200 FDA-cleared?
No. The ST2200 is CE-certified, ISO 13485-compliant, ISO 9001-compliant, and SGS-certified — but it is not FDA-cleared for medical use in the United States. It is sold for wellness, research, and recovery use. If you require FDA-cleared equipment for clinical documentation or insurance reimbursement, ask us about US-made FDA-cleared alternatives. Consult your physician before starting any HBOT protocol.
How long is a typical session and how often should I use it?
Most protocols run 60 to 90 minutes per session, 3 to 5 times per week. Beginners typically start at 45 minutes at 1.3 ATA for the first 2 weeks, then work up to longer sessions at higher pressure. Your physician should guide frequency based on your goals.
Do I need a doctor or technician to operate it?
No. The ST2200 is designed for self-operation. Setup takes 30 to 45 minutes the first time — 10 to 15 minutes after. Dual internal and external pressure controls let you operate solo or have an attendant monitor. You'll get video walkthroughs and written setup guides after purchase. Consult your physician before starting HBOT, but daily operation doesn't require medical supervision.
What should I wear and how should I prepare?
Loose, comfortable clothing. Remove shoes, jewelry, and any electronics that could produce sparks. Avoid caffeine, alcohol, carbonated drinks, and smoking before sessions — they can intensify pressure sensations. Clear your sinuses beforehand so you can equalize ear pressure cleanly.
What will I feel during a session?
You'll hear steady airflow and feel gradual ear pressure during pressurization — similar to an aircraft takeoff. Some users feel slight fatigue or lightheadedness for 10 to 15 minutes after their first few sessions. This typically resolves as the body adapts over the first 2 weeks of use.
How do I equalize ear pressure?
Use the Valsalva maneuver (pinch your nose and gently exhale), yawning, or swallowing during pressurization. The ST2200 pressurizes slowly enough that most users equalize naturally. If you can't equalize due to a cold, sinus congestion, or ear infection, skip the session.
Is claustrophobia a concern in a soft-shell chamber?
Soft-shell chambers have a higher claustrophobia dropout rate than hard-shell. The ST2200's upright sitting design helps — you're not lying in a tube. Four large viewing windows reduce the enclosed feeling further. First-time users typically acclimate within 2 to 3 sessions. If severe claustrophobia is a known issue, request a video walkthrough before buying.
Can I stack red light therapy with HBOT?
Yes — the ST2200 has an optional 660 nm + 850 nm red light therapy panel designed to integrate with sessions. HBOT increases oxygen delivery to tissues while red light therapy boosts cellular energy production. Stacked protocols typically run 20-minute RLT exposure inside the chamber during HBOT. Consult your physician on protocol design.
