Effects of thoraco-pelvic supports during prone position in patients with acute lung injury/acute respiratory distress syndrome: a physiological study

Table 2 Detailed contact pressures at different sites and global values

Position	Units	Supine	Prone without supports	Prone with supports
Thorax	cmH₂O	15.4 ± 4.1	17.0 ± 7.4	29.0 ± 6.5^a,b
Abdomen	cmH₂O	5.8 ± 2.9	11.0 ± 1.8^a	0.0 ± 0.0^a,b
Sacrum/pubis	cmH₂O	8.0 ± 5.7	4.5 ± 4.2	28.3 ± 8.9^a,b
Global	cmH₂O	9.7 ± 5.8	10.8 ± 7.0	19.1 ± 15.2^a,b

Results are means ± SD. ^ap ≤ 0.05 compared with supine; ^bp ≤ 0.05 compared with prone without supports.
