Tidal volume challenge–induced hemodynamic changes can predict fluid responsiveness during one-lung ventilation: an observational study [PDF]

Frontiers in Medicine, 2023
BackgroundTo evaluate the ability of tidal volume challenge (VTC)-induced hemodynamic changes to predict fluid responsiveness in patients during one-lung ventilation (OLV).Methods80 patients scheduled for elective thoracoscopic surgery with OLV were ...

Does tidal volume challenge improve the feasibility of pulse pressure variation in patients mechanically ventilated at low tidal volumes? A systematic review and meta-analysis [PDF]

Critical Care, 2023
Background Pulse pressure variation (PPV) has been widely used in hemodynamic assessment. Nevertheless, PPV is limited in low tidal volume ventilation. We conducted this systematic review and meta-analysis to evaluate whether the tidal volume challenge ...

The role of the tidal volume challenge test in volume responsiveness assessment: a narrative review [PDF]

Journal of Anesthesia, Analgesia and Critical Care
The accurate prediction of volume responsiveness is fundamental to goal-directed fluid administration. Targeted fluid administration during surgery is critical to avoid hypervolemia or hypovolemia and their associated postoperative complications ...

Tidal volume challenge to predict preload responsiveness in patients with acute respiratory distress syndrome under prone position [PDF]

Critical Care, 2022
Background Prone position is frequently used in patients with acute respiratory distress syndrome (ARDS), especially during the Coronavirus disease 2019 pandemic. Our study investigated the ability of pulse pressure variation (PPV) and its changes during

Efficacy of using tidal volume challenge to improve the reliability of pulse pressure variation reduced in low tidal volume ventilated critically ill patients with decreased respiratory system compliance [PDF]

BMC Anesthesiology, 2022
Background The prediction accuracy of pulse pressure variation (PPV) for fluid responsiveness was proposed to be unreliable in low tidal volume (Vt) ventilation.

The predictive value of tidal volume challenge-induced hemodynamic changes for fluid responsiveness in patients undergoing thoracoscopic surgery with one-lung ventilation: a prospective observational study [PDF]

BMC Anesthesiology
Background Video-assisted thoracic surgery (VATS) relies on one-lung ventilation (OLV) to achieve optimal surgical conditions. However, the lung protective ventilation strategies commonly employed during OLV diminish the accuracy of traditional dynamic ...

The tidal volume challenge improves the reliability of dynamic preload indices during robot-assisted laparoscopic surgery in the Trendelenburg position with lung-protective ventilation [PDF]

BMC Anesthesiology, 2019
Background The reliability of pulse pressure variation (PPV) and stroke volume variation (SVV) is controversial under pneumoperitoneum. In addition, the usefulness of these indices is being called into question with the increasing adoption of lung ...

Changes in internal jugular vein respiratory variation during tidal volume challenge predict volume responsiveness in lumbar surgery under protective ventilation: a prospective cohort study [PDF]

Journal of Intensive Care
Background Internal jugular vein respiratory variation (IJVV) has been proposed as a dynamic predictor of fluid responsiveness. However, its utility is limited in patients with low tidal volume (Vt) ventilation in the prone position.

Assessment of fluid responsiveness after tidal volume challenge in renal transplant recipients: a nonrandomized prospective interventional study [PDF]

Clinical Transplantation and Research
Background : When applying lung-protective ventilation, fluid responsiveness cannot be predicted by pulse pressure variation (PPV) or stroke volume variation (SVV). Functional hemodynamic testing may help address this limitation.
