Effect of individualized PEEP titration guided by intratidal compliance profile analysis on regional ventilation assessed by electrical impedance tomography – a randomized controlled trial

Table 3 Frequencies of compliance profiles from 48 patients

Compliance profile	Control (n = 23)	Intervention (n = 25)	p-value
Horizontal (%)	85.5 (28.1)	92.8 (9.6)	0.1162
Merely Increasing (%)	9.6 (20.8)	3.5 (6.4)	0.1727
Increasing-horizontal (%)	3.8 (8.5)	2.9 (4.8)	0.6626
Merely Decreasing (%)	0.2 (0.5)	0	0.4379
Horizontal-decreasing (%)	0.2 (0.8)	0.6 (1.9)	0.0797
Mixed (%)	0.7 (3.0)	0.4 (1.6)	0.6816

Differences between the two groups were assessed with Mann-Whitney U tests. Frequencies were adapted to the duration of mechanical ventilation. Data are expressed as mean (SD)
