Soft vs Hard: ATA Pressure Explainer
See how chamber pressure changes the oxygen your blood can carry — and which MACY-PAN chamber fits.
1.5 ATA
1.3 (mild/soft)
1.5
2.0 (medical hard)
Relative dissolved oxygen in plasma: ~115% of 1.3 ATA baseline (Henry’s Law — dissolved O₂ rises in proportion to pressure)
Educational model. Dissolved-plasma oxygen scales with absolute pressure (Henry’s Law); shown relative to a 1.3 ATA baseline. Combined (hemoglobin) oxygen is near-saturated at all these pressures. Published anti-aging skin trials used 2.0 ATA.
