What does the evidence show about Hyperbaric oxygen therapy (HBOT)'s effects?

Read Off Label rates the evidence for Hyperbaric oxygen therapy (HBOT) as Moderate and the benefit magnitude as med / varies, producing an overall grade of C+ (5.5/10). Hachmo 2020: 60 HBOT sessions in older adults increased telomere length >20% and reduced senescent cells 10-37%.

What safety findings are reported for Hyperbaric oxygen therapy (HBOT)?

Hyperbaric oxygen therapy (HBOT) has a med risk profile in the database. Med (barotrauma, oxygen toxicity, fire risk) Legal status: Available at specialty clinics.

What doses or routes are reported for Hyperbaric oxygen therapy (HBOT)?

2.0-2.4 ATA x 60-90 min; protocols vary; Hachmo aging trial used 60 sessions This is context from studies, approved labeling, clinical practice, or documented use; it is not individualized guidance and does not establish safety.

Bottom line

Read Off Label grades Hyperbaric oxygen therapy (HBOT) as C+ (5.5/10) based on moderate evidence, med / varies benefit magnitude, and a med-risk safety profile.

Hachmo 2020: 60 HBOT sessions in older adults increased telomere length >20% and reduced senescent cells 10-37%.

Studied, labeled, or reported-use context: 2. — Available at specialty clinics; not individualized guidance.

What the evidence says

Hachmo 2020: 60 HBOT sessions in older adults increased telomere length >20% and reduced senescent cells 10-37%. Expensive ($200-500/session). Not covered by insurance for anti-aging indications.

Mechanism

Hyperoxic-hypoxic paradox: high oxygen pressure increases tissue oxygenation then triggers HIF-1α response upon return to normoxia; stem cell mobilization; angiogenesis; reduced inflammation

Studied, labeled, or reported dose & route

2.0-2.4 ATA x 60-90 min; protocols vary; Hachmo aging trial used 60 sessions

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
