Who should buy which

Pick the OxyHealth Fortius 420 if

Buyers who specifically need hard-shell clinical pressures above the soft 1.3 ATA tier in a single-occupant chamber. Family offices and private suites building a clinical-grade hyperbaric setup.

Skip if

You only need mild 1.3 ATA HBOT (the soft-shell Vitaeris or Solace are sufficient and far simpler), or you can't accommodate the 12×6 ft + ceiling footprint.

Pick the PCCI Hyperbaric Systems 8400 Series Multiplace if

Longevity and wound-care clinics, and fully built-out private medical suites running a multi-person hyperbaric program with trained staff and facility certification.

Skip if

You are any kind of individual or home buyer. This is clinic-scale medical infrastructure. The Sechrist monoplace is the clinical-grade single-user step down; a soft-shell OxyHealth chamber is the realistic home tier.
