Objective: To evaluate to which extent the systemic arterial pulse pressure could be used as
a surrogate of cardiac output for assessing the effects of a fluid challenge and of …

Objective: This study aims to describe the pharmacodynamics of a fluid challenge over a 10-
minute period in postoperative patients. Design: Prospective observational study. Setting …

Purpose To assess whether invasive and non-invasive blood pressure (BP) monitoring
allows the identification of patients who have responded to a fluid challenge, ie, who have …

Objective: To assess the effects of norepinephrine on cardiac preload, cardiac index, and
preload dependency during septic shock. Design: Prospective interventional study. Setting …

Objectives: Norepinephrine exerts venoconstriction that could increase both the mean
systemic pressure and the resistance to venous return, but this has not yet been investigated …

Objective: To investigate whether stroke volume variations obtained with the pressure
recording analytic method can predict fluid responsiveness in mechanically ventilated …

Objective: During mechanical ventilation, inspiration cyclically decreases the left cardiac
preload. Thus, an end-expiratory occlusion may prevent the cyclic impediment in left cardiac …

Sir: We read the review by Bendjelid and Romand [1], describing the indices that have been
proposed to predict fluid responsiveness in critically ill patients, with great interest. In this …

Objective To examine whether the hemodynamic changes due to mechanical ventilation
with positive end-expiratory pressure (PEEP) can be assessed by the respiratory-induced …

Objective: To investigate the effect of norepinephrine on static (right atrial pressure,
pulmonary artery occlusion pressure) and dynamic (pulse pressure variation and arterial …
