Key Differences at a Glance
Construction: Hard-shell chambers use a rigid structure. Soft-shell chambers use a flexible enclosure.
Pressure: Hard-shell systems are typically capable of higher treatment pressures. Soft-shell systems generally operate at lower pressures.
Oxygen delivery: Hard-shell systems can support protocols in which the patient breathes high-concentration oxygen under pressure. Soft-shell delivery varies and may involve pressurized room air with separate supplemental oxygen.
Clinical use: Hard-shell chambers are used for recognized medical indications and may also be used for provider-guided supportive care. Soft-shell systems are often marketed for wellness or mild hyperbaric use.
