Yes — and this is one of the most common misconceptions I address at Pulmovista Clinics. Pulmonary rehabilitation is not only safe for Stage 4 patients on home oxygen — it is specifically designed for them. At Pulmovista, all exercise for oxygen-dependent patients is conducted with supplemental oxygen titrated to maintain SpO₂ above 88–90% throughout. The exercise prescription is adapted to the patient’s actual exercise capacity — starting conservatively and progressing gradually. Our continuous monitoring means any deterioration is identified and addressed immediately. Stage 4 patients on home oxygen consistently achieve meaningful improvements in exercise capacity and quality of life through the Pulmovista programme.
