HBOT — Single Session (1 × 60 min)

Single 60-minute hyperbaric oxygen session at REH-AS in Kraków Nowa Huta. Soft-shell mild-HBOT chamber operating at 1.4 ATA, with pure oxygen delivered through a mask under qualified-staff monitoring. Pay-per-session entry — used by first-time visitors before committing to the 10-pack or 15-pack protocol.

REH-AS's single-session HBOT is a stand-alone 60-minute booking inside a soft-shell chamber pressurised to 1.4 ATA (atmospheres absolute). At 1.4 ATA the in-chamber pressure is comparable to descending roughly 4 metres below sea level, increasing the partial pressure of oxygen in the bloodstream relative to ambient room air. Pure oxygen is administered via a mask during the session, under qualified-staff supervision (the clinic states 'wykwalifikowana osoba monitorująca' is present throughout each procedure). REH-AS is a Kraków rehabilitation and orthopaedics centre operating since 2004, and frames HBOT as an adjunct service alongside its core lower-limb prosthetics, orthopaedic insole, scoliosis-corset, and rehabilitation diagnostics offering. The clinic lists circulatory support, post-surgical recovery, neurological-recovery support, sports-recovery, diabetes adjunct, and aesthetic uses among the conditions clients use the chamber for. None of those uses are clinical-grade indications: 1.4 ATA mild HBOT is wellness-tier, not the ≥2.0 ATA hard-shell pressure required for UHMS-recognised hospital indications such as decompression sickness, severe non-healing wounds, or carbon-monoxide poisoning. Patients with those indications need a hospital hyperbaric-medicine ward, not a wellness or rehab-tier chamber. The single-session block is the introductory option: pay 150 PLN once, try the chamber, then decide whether the 10-pack (110 PLN/session) or 15-pack (100 PLN/session) protocol fits your goals. Per-session it is the most expensive of the three publicly listed options. Booking is taken by phone (+48 12 686 43 28) or via the contact page on rehas.pl. The clinic operates Mon–Fri 8:00–16:00; weekend hours are not published despite a note on the site implying 7-day operation. The site is Polish-only — English-language support is not advertised. The chamber manufacturer and model are not disclosed on the REH-AS website. Confirm with the clinic if either spec is material to your protocol.
