HBOT — Long Session (150 min @ 1.3 ATA, regulars only)

Single 150-minute long session — available only to OXIMA's existing/regular clients. Same NT2200 soft-shell chamber at 1.3 ATA. Booking via phone (+48 573 328 000).

OXIMA's deepest single-session option is a 150-minute slot reserved for regular clients. After roughly 15-20 minutes of compression and decompression, the in-chamber portion at full 1.3 ATA pressure runs for around 130 continuous minutes — long enough that most clients use the slot for a full nap or a long focused work block on a tablet. The chamber itself is the same NT2200 soft-shell unit used for shorter sessions, with 93% oxygen delivered from a concentrator via the client's preferred mask / cannula / nasal-prongs interface. No discounted carnet is offered at this duration; clients pay 200 PLN per session. The slot is priced as a roughly 33% per-minute discount versus stacking two 60-minute sessions back-to-back, which is OXIMA's deliberate pricing pattern — the longer you stay, the cheaper each in-chamber minute becomes. Like all OXIMA sessions this is wellness-tier mild HBOT, the NT2200 is not a medical device under EU MDR 2017/745, and the studio explicitly does not offer disease treatment. Long sessions amplify ear-pressure discomfort if you're congested; reschedule if you have any cold or flu symptoms on the day.
