Study type
Description of intervention(s) / exposure
The study will be conducted over a 6-8 day period during a hospital admission for hypercapnic respiratory failure. On day 1, baseline anthropometric data, measurement of exercise capacity, quality of life, an arterial blood gas, spirometry and maximum inspiratory and expiratory muscle pressures at the mouth were collected. Day 2 subjects were randomised to either a control or early exercise rehabilitation with supplemental oxygen or early exercise rehabilitation group (with non-invasive ventilation and supplemental oxygen). All groups receive standard medical care, including non-invasive ventilation at rest as required. Early rehabilitation consists of a supervised, progressive exercise program of approximately 20-30 minutes each day for at least 4 days. Day 6-8 baseline measures repeated.
