Design Prospective measurement study Setting Operating room in the university hospital Patients 12 patients (ASA physical status 1-2) who underwent elective surgery Methods Simultaneous readings of SVV from VigileoTMFlotrac system and PPV while gradually increasing and then decreasing positive end-expiratory pressure (PEEP) from 0 to 15 cm H2O in 5 cm H2O increments. Main Results SVV significantly increased with PEEP >10 cm H2O, being variously 6% ± 2% (PEEP = 0 cm H2O), 8% ± 2% (PEEP = 5 cm H2O), 11% ± 6% (PEEP = 10 cm H2O), 17% ± 10% (PEEP = 15 cm H2O), 11% ± 8% (PEEP = 10 cm H2O), 7% ± 3% (PEEP = 5 cm H2O), and 6% ± 1% (PEEP = 0 cm H2O). PPV values significantly increased at a PEEP of 15 cm H2O, being variously 7% ± 4% (PEEP = 0 cm H2O), 8% ± 4% (PEEP = 5 cm H2O), 10% ± 4% (PEEP = 10 cm H2O), 13% ± 5% (PEEP = 15 cm H2O), 10% ± 4% (PEEP = 10 cm H2O), 7% ± 4% (PEEP = 5 cm H2O), and 6% ± 3% (PEEP = 0 cm H2O). Conclusions SVV derived from VigileoTMFlotrac system was significantly increased under a PEEP of 10 and 15 cm H2O, although PPV values were not significantly affected at a PEEP of 10 cm H2O and below. Hence, SVV derived from VigileoTMFlotrac system might overestimate fluid responsiveness under PEEP > 10 cm H2O.}, pages = {71--75}, title = {Effects of respiratory settings on stroke volume variation derived from the Vigileo Flotrac system: comparison with pulse pressure variation(和訳中)}, volume = {22}, year = {2018} }
