Effect of position on ProSeal™ LMA
Parameter | Supine position | Lateral position | P |
---|---|---|---|
VTI (ml) | 151.18±59.36 | 151.18±59.36 | |
VTE (ml) | 148.76±58.35 | 147.44±59.04 | 0.105 |
FVL (%) | 1.51±2.83 | 2.76±4.06 | 0.040 |
Seal pressure (cm H2O) | 17.53±5.04 | 12.76±3.36 | 0.000 |
EtCO2 (mmHg) | 37.32±3.37 | 38.76±3.59 | 0.001 |
Data are expressed as mean±standard deviation. The P<0.05 is statistically significant. VTI – Inspired Tidal volume, VTE – Expired Tidal volume, FVL – Fractional volume loss
