Table 3.

Self-reported sleep comfort and sleep quality evaluated following 6 weeks of high-pressure and high-intensity noninvasive ventilation

	High-pressure NIV (PSV)	High-intensity NIV (PCV)	Mean difference	P value (95% CI)
Sleep comfort VAS (mm)	57 ± 29	58 ± 29	−1 (−40 to 37)	0.944
Sleep quality (0–5 scale)	3.3 ± 0.3	3.2 ± 0.6	0.1 (−0.3 to 0.7)	0.638

Notes: Sleep comfort VAS: 0–100 mm (0, least comfortable; 100, most comfortable). Sleep quality: 0 to 5 (0, least quality; 5, best quality).

Abbreviations: CI, confidence interval; VAS, visual analog scale; PSV, pressure support ventilation; PCV, pressure-controlled ventilation; NIV, noninvasive ventilation.
