Figure 4From: Pulse pressure variation and stroke volume variation during increased intra-abdominal pressure: an experimental studyRelation between changes in SV with FL and SVV or PPV before FL. Definition of abbreviations: FL, fluid loading; PPV, pulse pressure variation; SV, stroke volume; SVV, stroke volume variation. FL was performed at intra-abdominal pressure of 30 mmHg in 9 pigs before blood withdrawal and 7 pigs after blood withdrawal (see also text).Back to article page
