Backed by peer-reviewed research.
SmartOx builds on a body of peer-reviewed trials and meta-analyses in COPD oxygen therapy. The figures here come from published studies of the clinical approach, in exercise and hospital settings. They are not SmartOx trial results, and full references are available on request.

Fewer days in hospital, lower cost of care.
Hospital studies of the same clinical approach show shorter stays, more time in the target oxygen range, and lower per-patient costs.
The cost of the gap shows up in the hospital.
COPD is one of the most frequent reasons Americans return to the hospital within a month of leaving it. Readmissions are expensive, often preventable, and closely tied to how patients are doing at home.
Drops go unseen at home.
Patients on home oxygen can fall below safe oxygen levels during ordinary daily activity. A resting check in clinic will not catch it.
The clinic finds out late.
Clinicians usually learn how a patient is doing at the next scheduled visit, or once something has already gone wrong.
Exacerbations are ~50% more likely.
Patients who desaturate during a walking test were about 50% more likely to have had an exacerbation in the past year, the kind that sends a patient back to the hospital.
