OxyHealth Vitaeris 320
FDA-cleared soft-shell chamber, the most-installed home HBOT unit in the US. Operates at 1.3–1.4 ATA — useful for recovery and mitochondrial endpoints, below the Efrati protocol pressure for senescence work.

Hyperbaric Oxygen Therapy
Grade B — Tel Aviv telomere-and-senescence RCT pushed HBOT into longevity conversations; protocol matters.
The evidence
Hyperbaric oxygen therapy at 2.0 ATA delivered as 40 daily sessions in Shai Efrati's 2020 Tel Aviv trial produced telomere elongation and senescent-cell reduction in older adults. The protocol — 60-minute sessions, intermittent 100% O2 with 5-minute air breaks — is replicable and is now offered in dozens of US clinics. Lower-pressure (1.3 ATA) soft chambers used by most home buyers do not match the trial protocol; clinical-grade results require clinical-grade pressure.

Halacha notes
Kosher Evidence Card
- Halacha — Shabbat
- Electronic compressor activation is a melacha. Pre-set timer cycles raise grama questions.
- Halacha — Yom Tov
- Same as Shabbat for elective use.
- Choleh Status
- Documented diagnoses like long COVID neurological sequelae, post-stroke rehab, and refractory wound healing may rise to choleh-relevant; discuss with your rav and physician together.
- Clinic Notes
- Most clinical chambers are single-occupancy — no mixed-gender concerns.
- Test Before Use
- ENT exam (Eustachian tube clearance); ophthalmology review if cataracts or recent eye surgery; pulmonary function if obstructive lung disease.
- Ask Your Rav About
- Whether the indication qualifies as choleh she-ein bo sakanah for the specific therapy schedule; how to handle the 40-session daily protocol if it crosses Shabbat.
FAQ
Soft chamber 1.3 ATA vs. hard chamber 2.0 ATA — does it matter?
Yes. The Efrati telomere and senescence data is on 2.0 ATA hard-chamber protocols. Soft-chamber 1.3 ATA is useful for mitochondrial and recovery endpoints but is not interchangeable with the published longevity results.
How many sessions are needed?
Efrati's protocol is 40 sessions, 5 days a week for 8 weeks. Shorter courses produce some benefit but the dose-response in the trial was real.
Is mobile HBOT real?
Mobile chamber services exist for in-home concierge HBOT. Pricing varies widely — confirm the actual operating pressure before booking.
