This cross-sectional physiological study evaluated cough assistance techniques in adolescents and young adults with neuromuscular diseases using home noninvasive ventilation. The study found that peak cough flow (PCF) significantly increased with manual assisted cough, air stacking, and mechanical insufflation-exsufflation, with PCF reaching 306.7 ± 98.4 L/min when combined with manual assisted cough. Vital capacity also improved with certain techniques.
Key findings
- Baseline peak cough flow (PCF) was 211.2 ± 89.4 L/min.
- PCF increased significantly with manual assisted cough, air stacking, and mechanical insufflation-exsufflation (all p < 0.05).
- Combining techniques with manual assisted cough further increased PCF, e.g., air stacking + MAC resulted in 306.7 ± 98.4 L/min.
- Vital capacity increased after air stacking, mechanical insufflation-exsufflation, and NIV (all p < 0.005).
Why it matters
Improving cough effectiveness in patients with neuromuscular diseases is crucial for reducing respiratory morbidity. This study highlights effective techniques that can enhance respiratory function in this vulnerable population.
