Early home-based pulmonary rehabilitation is feasible and safe for post-hospitalisation exertional hypoxaemia patients, but adding high-flow nasal oxygen reduces adherence.
This pilot feasibility trial found that a 3-week home-based pulmonary rehabilitation program for patients with exertional hypoxaemia after hospital discharge had 67% acceptance and 62% uptake. However, the addition of high-flow nasal oxygen during exercise training was associated with lower program completion (60% vs 89%) and reduced adherence to self-directed sessions.

Early home-based pulmonary rehabilitation is feasible and safe for post-hospitalisation exertional hypoxaemia patients, but adding high-flow nasal oxygen reduces adherence. The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 44/100 (low).
The Claim
Early home-based pulmonary rehabilitation is feasible and safe for post-hospitalisation exertional hypoxaemia patients, but adding high-flow nasal oxygen reduces adherence.
This conclusion is most relevant to: Post-hospitalisation patients with exertional hypoxaemia across respiratory conditions (including COPD)..
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸High-Flow Nasal Oxygen in Early Home Pulmonary Rehabilitation for Exertional Hypoxaemia: A Pilot Randomised Feasibility Trial. (Respirology (Carlton, Vic.), 2026) —
How It Works
The proposed biological pathway:
- ▸Patients with exertional hypoxaemia experience rapid deconditioning after hospital discharge
- ▸Early pulmonary rehabilitation is limited by exercise intolerance and access barriers
- ▸High-flow nasal oxygen may alleviate exertional hypoxaemia during exercise
- ▸Home-based PR with HFO showed lower adherence and completion rates than PR alone
Who Might Benefit
Evidence fit by population:
- ▸Post-hospitalisation patients with exertional hypoxaemia across respiratory conditions (including COPD).
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Pilot feasibility trial with small sample size (56 patients randomised, 52 completed follow-up)
- ▸Lower adherence in HFO-PR group may reflect implementation challenges rather than efficacy of HFO itself
Frequently Asked Questions
What is exertional hypoxaemia?▼
Exertional hypoxaemia is a condition where blood oxygen levels drop significantly during physical activity, often occurring in patients with chronic respiratory diseases after hospitalisation.
Did high-flow nasal oxygen improve exercise capacity in this study?▼
No, the study did not show a significant improvement in exercise capacity (1-min sit-to-stand test) with HFO compared to PR alone; the adjusted difference was -0.8 repetitions with wide confidence intervals.
Why was adherence lower in the HFO-PR group?▼
Participants reported challenges with the HFO system during unsupervised exercise, which likely contributed to reduced adherence to self-directed sessions.
Is home-based pulmonary rehabilitation safe for these patients?▼
Yes, the study concluded that early home-based PR for post-hospitalisation exertional hypoxaemia patients is feasible and safe.
