% of breaths | COPD | NMD-CWD | ORRF | p Value |
---|---|---|---|---|
% Premature expiratory cycling | 1 (0–4) | 1 (0–4) | 1 (0–2) | 0.9 |
% Delayed expiratory cycling | 2 (0–7) | 2 (0–5) | 0 (0–3) | 0.5 |
% Auto-cycling | 1 (0–4) | 0 (0–0) | 0 (0–0) | 0.2 |
% Total cycling asynchrony | 7 (4–10) | 4 (3–6) | 3 (1–7) | 0.2 |
A Kruskal-Wallis test was used to compare patient-ventilator asynchrony between disease groups, p value <0.05 was taken to represent statistical significance.
NMD-CWD, neuromuscular disease with or without chest wall disease; ORRF, obesity related respiratory failure.
