Evaluation of respiratory mechanics variables at different body positions
| Variable | Position | Values |
|---|---|---|
| Resistive pressure (cmH2O) | P1 | 11.6 ± 3.5 (10.4 - 12.8)* |
| P2 | 10.9 ± 3.8 (9.6 - 12.2) | |
| P3 | 10.8 ± 3.2 (9.6 - 11.9) | |
| P4 | 10.8 ± 3.5 (9.6 - 12.0) | |
| Elastic pressure (cmH2O) | P1 | 17.4 (14.0 - 22.1) |
| P2 | 16.6 (13.7 - 21.4) | |
| P3 | 17.3 (14.8 - 23.8) | |
| P4 | 19.3 (16.1 - 25.3)* | |
| Cst, rs (mL/cmH2O) | P1 | 27.1 (19.5 - 32.3) |
| P2 | 27.0 (20.7 - 34.8) | |
| P3 | 25.2 (18.4 - 31.5) | |
| P4 | 24.5 (17.4 - 29.9)* | |
| Cdyn, rs (mL/cm H2O) | P1 | 15.4 (12.3 - 20.2) |
| P2 | 16.4 (12.7 - 19.5)* | |
| P3 | 15.6 (13.7 - 19.1) | |
| P4 | 14.6 (11.8 - 18.7) | |
| SpO2 (%) | P1 | 97.0 (96.0 - 98.0) |
| P2 | 97.0 (96.0 - 98.0) | |
| P3 | 96.0 (96.0 - 97.0) | |
| P4 | 96.0 (96.0 - 97.0) |
Cst, rs - static compliance; Cdyn, rs - dynamic compliance; SpO2 - pulse oximetry. Results are expressed as the mean ± standard deviation (95% confidence interval) or median (25%-75%).
