From: Perioperative hemodynamic optimization: from guidelines to implementation—an experts’ opinion paper
Methods (year of first validation) | Main advantages | Main limitations |
|---|---|---|
PPV (2000) | Automatically calculated by most bedside monitors | Need for general anesthesia, an arterial line and a tidal volume > 7 ml/kg |
SVV (2001) | Automatically calculated by most CO monitors | Need for a CO monitor, general anesthesia, an arterial line and a tidal volume > 7 ml/kg |
Changes in CO during a PLR maneuver (2006) | Useful when Vt < 7 ml/kg IBW | Need for a CO monitor, PLR maneuver difficult to perform during surgery |
PVI (2008) | Non-invasive from a pulse ox | Need for general anesthesia and a tidal volume > 7 ml/kg, influenced by peripheral perfusion |
Changes in SV during an EEO test (2009) | Useful when Vt < 7 ml/kg IBW | Need for a CO monitor, prone to error measurements (small magnitude of changes in SV) |
Changes in SV during a mini-fluid challenge (2011) | Useful when Vt < 7 ml/kg IBW | Need for a CO monitor, prone to error measurements (small magnitude of changes in SV) |
Changes in PPV during a mini-fluid challenge (2015) | Useful when Vt < 7 ml/kg IBW | Prone to error measurements (small magnitude of changes in PPV) |
Changes in PPV during a Vt challenge (2017) | Useful when Vt < 7 ml/kg IBW | Prone to error measurements (small magnitude of changes in PPV) |
Changes in SV during a LRM (2017) | Useful when Vt < 7 ml/kg IBW | Need for a CO monitor |
Changes in PI during a PLR maneuver (2019) | Useful when Vt < 7 ml/kg IBW, non-invasive (pulse ox) | Influenced by peripheral perfusion, PLR maneuver difficult to perform during surgery Low level of scientific validation |
Changes in PI during a LRM (2020) | Useful when Vt < 7 ml/kg IBW, non-invasive (pulse ox) | Influenced by peripheral perfusion Low level of scientific validation |
