Pulse pressure variation, stroke volume variation and dynamic arterial elastance [PDF]
Critical Care, 2011 We read with interest the recent article by Monge Garcia and colleagues [1]. We have two comments regarding this interesting physiological study. First, although we support their observation [2], their explanations may lead to some confusion. Indeed, the Edwards Vigileo™ system-FloTrac™ sensor calculates stroke volume (SV) using the equation:

Pulse pressure variation: beyond the fluid management of patients with shock [PDF]
Critical Care, 2007 In anesthetized patients without cardiac arrhythmia the arterial pulse pressure variation (PPV) induced by mechanical ventilation has been shown the most accurate predictor of fluid responsiveness. In this respect, PPV has so far been used mainly in the decision-making process regarding volume expansion in patients with shock.

Pulse pressure variation and adrenal insufficiency in septic shock [PDF]
Critical Care, 2007 It is known that corticosteroid therapy improves the hemodynamic state in patients with septic shock and relative adrenal insufficiency. This effect is partially due to a direct action on vascular tone in the more vasoplegic patient, so they may be more hypovolemic.

A randomized comparison between pulse pressure variation and central venous pressure in patients undergoing renal transplantation [PDF]
Journal of Anaesthesiology Clinical Pharmacology, 2021 Background and Aims: Intraoperative fluid management is important in renal transplant recipients with end-stage renal disease. Conventionally, central venous pressure (CVP) has been used to guide perioperative fluid administration but with high incidence

Should pulse pressure variation be indexed to tidal volume? [PDF]
Critical Care, 2009 Pulse pressure variation (PPV) for prediction of fluid responsiveness depends on the tidal volume (VT), and using VTs of the recommended 6 ml/kg makes PPV unreliable [1]. So far, nobody has suggested how to handle the VT when interpreting PPV or other dynamic parameters, but we hypothesise that PPV is proportional to VT and thus that PPV should be ...

Finger and forehead photoplethysmography-derived pulse-pressure variation and the benefits of baseline correction. [PDF]
J Clin Monit Comput, 2019 To non-invasively predict fluid responsiveness, respiration-induced pulse amplitude variation (PAV) in the photoplethysmographic (PPG) signal has been proposed as an alternative to pulse pressure variation (PPV) in the arterial blood pressure (ABP ...
