The congestive heart failure is a common disease among patients who receive cardiac surgery and may lead to prolonged ventilation support. Nesiritide was a potential therapy for congestive heart failure. This study aimed to compare the Nesiritide induced hemodynamical status changes among congestive heart failure patients with invasive ventilation support.

RECRUITINGChanges of cardiac output
Changes of cardiac output measured by hemodynamical monitoring tools
Time frame: Before and 30-min after using a standard dose of Nesiritide
Changes of systemic filling pressure
Changes of the intercept of regression line of paired VR-RAP points at different PEEP levels.
Time frame: Before and 30-min after using a standard dose of Nesiritide
Changes of cardiac function curve
Using body position changes (±15°) to simulate the change of preload, and therefore depicte the Starling curve
Time frame: Before and 30-min after using a standard dose of Nesiritide
Changes of venous return curve
Changes of venous return curve depicted by different PEEP setting
Time frame: Before and 30-min after using a standard dose of Nesiritide
