Assessing differences between inspiratory and expiratory haemodynamics allows comparison of cardiac function at different levels of cardiac preload without requiring fluid administration (9).
In addition to influencing indices of fluid responsiveness, positive pressure ventilation possibly alters cardiac preload dependence (50).
Continuously assessed right ventricular end-diastolic volume as a marker of cardiac preload and fluid responsiveness in mechanically ventilated cardiac surgical patients.
Estimation of cardiac preload changes by systolic pressure variation in pigs undergoing pneumoperitoneum.
End-diastolic volume versus pulmonary artery wedge pressure in evaluating cardiac preload in trauma patients.
Cardiac preload is a physiological concept that accounts for the relationship between ventricular filling and stroke volume.
