The Type of Chamber Makes All The Difference

Mild/Soft Shell vs Hard Shell

When looking for Hyperbaric Treatments, It’s important to know the difference

O2 Be Well ONLY uses medical grade Hard Shell chambers that go to 2.1 ATA.

Soft chambers do not provide the same benefits as hard shell chambers.  In most case studies, a medical grade hard shell chamber is used to prove the benefit of hyperbaric oxygen therapy.  Soft shell chambers only go up to 1.3 ATA and do not provide enough pressure to put a therapeutic amount of oxygen which is the true benefit  of this therapy.  Soft shell chambers only increase oxygen intake by  6.3% above normal atmosphere that we breath which is 21%

Differences between Medical Grade Hard-Shell and Mild/Soft Shell Hyperbaric Chambers:

  • Soft chambers lack benefits of medical-grade ones.
  • Mild/soft chambers may not justify their cost.
  • They often lack adequate pressure for therapeutic oxygen levels.
  • Using them for Hyperbaric Oxygen Therapy can be misleading.

Hyperbaric oxygen therapy is used to address non-healing wounds and combat bacterial, viral, and fungal infections. Research indicates that oxygen exhibits bacteriostatic properties at 1.5 ATA. This means that oxygen, beyond 1.5 ATA, hinders the growth of bacteria and fungi. In hard-shell hyperbaric oxygen therapy, pressure typically exceeds 2.0 ATA, effectively suppressing bacterial growth. Conversely, soft-sided chambers, operating at an average of 1.3 ATA, are unable to inhibit bacterial growth and may even promote the proliferation of bacteria, mold, and fungus. Such exposure can exacerbate conditions or lead to further medical complications.

Mild / Soft Chambers are NOT a recognized medical device and are only approved to treat altitude sickness

Mild / Soft chambers do not offer the same advantages as hard shell chambers in hyperbaric oxygen therapy. Typically, medical-grade hard shell chambers are utilized in case studies to demonstrate the therapy’s benefits. Mild/ Soft chambers only reach 1.3 ATA, failing to generate sufficient pressure to deliver a therapeutic dose of oxygen, which is the therapy’s primary advantage. They only increase oxygen intake by 6.3% above the 21% found in normal air, providing minimal additional benefits. In contrast, soft chambers are comparable to breathing regular air. For enhanced clarity, let’s examine arterial blood gas levels indicating oxygen content in the blood. Under normal air conditions and pressure, blood oxygen levels are around 157 mmHg. In a soft chamber at 1.3 ATA with 24% oxygen, this level rises to 230 mmHg. Comparatively, an oxygen mask used in ambulance transport offers 55% oxygen at normal pressure, resulting in 418 mmHg. The significant difference is observed in hard shell chambers, where at 2.4 ATA with 100% oxygen, arterial oxygen levels can surge to 1,824 mmHg.

Don’t put yourself or your family at risk medically just to save a little money. Some Mild or Soft chambers are made with rubber, plastic and petroleum products which off-gas in oxygen environments and expose those inside of them to toxicity by inhalation.
