Hyperbaric Oxygen Therapy (1.5 ATA)

The 1.5 ATA HBOT session at House of Salt delivers a higher atmospheric pressure than the entry-level 1.3 ATA option — roughly 50% above normal sea level, equivalent to approximately 5 metres below the water surface. This increased pressure further raises the partial pressure of dissolved oxygen in blood plasma, potentially enhancing tissue oxygenation beyond what the 1.3 ATA tier achieves.

At 1.5 ATA, the session sits in the upper range of what mild/wellness-tier HBOT chambers typically deliver. The 60-minute session duration is shorter than the 1.3 ATA option (90 minutes), reflecting the higher intensity of the pressure stimulus. The physiological responses at this pressure are well-documented: enhanced oxygen diffusion into tissues, upregulation of growth factors involved in wound healing, modulation of inflammatory pathways, and support…

Published research on 1.5 ATA HBOT has explored applications across post-concussion recovery, sports performance, wound healing, and general wellness. While the most robust clinical evidence for HBOT applies to higher pressures (2.0-2.4 ATA) used in hospital settings for conditions like non-healing wounds and decompression sickness, the 1.5 ATA tier has shown promise in wellness and recovery contexts.
