Evolution of ventilatory settings in randomised controlled trials investigating noninvasive ventilation in stable or post-exacerbation chronic obstructive pulmonary disease. IPAP: inspiratory airway pressure; EPAP: expiratory airway pressure; BURR: back-up respiratory rate.
- FIGURE 2
Forced expiratory volume in 1 s (FEV1) results in the RECOVER trial. FEV1 was measured at different points for the noninvasive intermittent positive pressure ventilation (NIPPV) + rehabilitation group (red triangles) and the rehabilitation group (blue squares). The change was significantly better in the NIPPV + rehabilitation group (p<0.02). Reproduced from [33] with permission from the publisher.
