HBOT — VIP Pack 20 × 80 min (1.3 ATA, 5-week validity)

Prepaid VIP carnet: 20 × 80-minute soft-shell HBOT sessions at 1.3 ATA. Total 1,500 PLN — 75 PLN per session (down from 130). 5-week validity from first use. Up to 3 named users may share simultaneous bookings.

OXIMA's deepest 80-minute carnet is 20 sessions for 1,500 PLN — 75 PLN per session, the lowest per-session rate the studio publishes. Validity is 5 weeks from first use, which works out to 4 sessions per week sustained over the full month-and-a-bit window. Like the 15-pack this is a prepaid named carnet: registered to one client with shared booking allowed across up to three named close family members or friends. Promotions don't stack with OXIMA's generic 5-20% prepaid-bundle discount tiers. The sessions are identical to standard 80-minute single sessions in spec — NT2200 soft-shell chamber, 1.3 ATA, 93% oxygen from a concentrator delivered through the client's choice of mask / cannula / prongs. Wellness-tier mild HBOT only; the NT2200 is not a medical device under EU MDR 2017/745, and OXIMA does not market this as disease treatment, diagnosis, or life-support. The per-session economics make this the lowest-cost-per-minute publicly bookable HBOT option at OXIMA. For clients with a clear 5-week recovery / conditioning window who can sustain ~4 sessions per week, it's the best value tier.
