Pulse pressure variation (PPV) is a well-known dynamic preload indicator to predict fluid responsiveness. However, its usefulness in open-chest conditions has been equivocal. The investigators evaluated whether PPV measured during Valsalva maneuver can predict fluid responsiveness after sternotomy.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Valsalva maneuver | This is an observational study and as a diagnostic intervention, subjects in the study would receive valsalva maneuver. Valsalva maneuver was performed after sternotomy with the constant airway pressure of 30cmH2O for 2 breaths duration. The investigators perform this procedure to every patients and do not assign this intervention to the subjects of the study. |
