The use of pulse pressure variation for predicting impairment of microcirculatory blood flow [PDF]
Scientific Reports, 2021 Dynamic parameters of preload have been widely recommended to guide fluid therapy based on the principle of fluid responsiveness and with regard to cardiac output. An equally important aspect is however to also avoid volume-overload.

Femoral Pulse Pressure Variation Is Not Interchangeable with Radial Pulse Pressure Variation during Living Donor Liver Transplantation. [PDF]
J Pers Med, 2022 The radial artery is commonly used as the site measuring pulse pressure variation (PPV) during surgery. Accurate measurement of circulating blood volume and timely interventions to maintain optimal circulating blood volume is important to deliver sufficient oxygen to tissues and organs.

Ventilator-induced pulse pressure variation in neonates. [PDF]
Physiol Rep, 2016 During positive pressure ventilation, arterial pressure variations, like the pulse pressure variation (PPV), are observed in neonates. However, the frequency of the PPV does not always correspond with the respiratory rate. It is hypothesized that PPV is caused by cardiopulmonary interaction, but that this mismatch is related to the low respiratory rate/

Pulse Pressure Variation-Guided Fluid Therapy during Supratentorial Brain Tumour Excision: A Randomized Controlled Trial. [PDF]
Open Access Maced J Med Sci, 2019 BACKGROUND: Goal-directed fluid therapy (GDFT) improved patient outcomes in various surgical procedures; however, its role during mass brain resection was not well investigated.

The pitfall of pulse pressure variation in the cardiac dysfunction condition. [PDF]
Crit Care, 2015 We read with interest the recent articles in Critical Care about the limitations of pulse pressure variation (PPV) for predicting fluid responsiveness [1, 2]. We believe that cardiac dysfunction should be included in this list of PPV limitations. During right ventricular (RV) dysfunction, the inspiration would increase RV afterload and lead to a ...

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits [PDF]
Clinics, 2010 OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.

Applicability of pulse pressure variation: how many shades of grey? [PDF]
Crit Care, 2015 Since its first description in 1999 [1], many studies have demonstrated the value of pulse pressure variation (PPV) as a predictor of fluid responsiveness. These studies were pooled together in a recent meta-analysis [2] concluding that PPV predicts fluid responsiveness accurately (sensitivity 88%, specificity 89%), so long as limitations to its use [3,

Does tidal volume challenge improve the feasibility of pulse pressure variation in patients mechanically ventilated at low tidal volumes? A systematic review and meta-analysis. [PDF]
Crit Care, 2023 Background Pulse pressure variation (PPV) has been widely used in hemodynamic assessment. Nevertheless, PPV is limited in low tidal volume ventilation. We conducted this systematic review and meta-analysis to evaluate whether the tidal volume challenge ...
