Summary: Hemodynamic monitoring plays a crucial role in acute care settings, but its effectiveness is hard to measure. This review summarizes the effectiveness of monitoring-linked resuscitation strategies, including process-specific monitoring, personalized resuscitation approaches, and machine learning methods. Future clinical trials should focus on process-specific monitoring to improve patient outcomes.

Summary: The overall performance of PPV and SVV in predicting fluid responsiveness in the operating room is moderate, approaching an AUC of 0.80 only in some subgroups of surgical patients. The wide grey zone of these dynamic indices should be carefully considered during the assessment of fluid responsiveness. Factors such as high tidal volume and the choice of colloids for fluid challenge may influence the reliability of PPV.

Summary: This study reports a wearable hemodynamic monitoring device that enables continuous monitoring of arterial pulse waves. It uses dual-channel bioimpedance to quantify pulse wave velocity and blood pressure. The research demonstrates the effect of contact pressure on bioimpedance and pulse wave velocity. The wearable dual-bioimpedance sensors provide reliable and continuous hemodynamic monitoring.

Summary: This study aimed to evaluate whether the changes in arterial pulse pressure (PP) and pulse pressure variation (PPV) during passive leg raising (PLR) can be used to assess preload responsiveness in patients with spontaneous breathing activity. The results showed that the changes in PP during PLR had a fair ability to evaluate preload responsiveness, even when norepinephrine was administered.

Summary: This study investigated the ability of pulse pressure variation (PPV) and its changes during a tidal volume challenge (TVC) to assess preload responsiveness in ARDS patients under prone position. The study found that changes in PPV during a TVC can reliably assess preload responsiveness in ARDS patients under low tidal volume ventilation during prone position.

Summary: The study found that peripheral intravenous waveform analysis (PIVA) can detect perioperative hemorrhage, and a blood loss of only 2% of the estimated blood volume can lead to significant changes in PIVA. Compared to other static, invasive, and dynamic markers, PIVA is most strongly associated with blood volume loss.

Summary: The study aimed to evaluate the incidence of fluid responsiveness in normotensive dogs under anaesthesia and assess the predictive value of PPV and PVI. The results showed that PPV and PVI had better diagnostic accuracy in predicting fluid responsiveness compared to SPV and SVV.

Summary: Hemodynamic monitoring in brain-dead donors presents challenges due to instabilities, and functional parameters such as pulse pressure variation and serum albumin level may be valuable markers for predicting volume responsiveness in this population.

Summary: This study analyzed the interactions between intracranial arteriovenous exchange and cerebrospinal fluid oscillations, and the results indicate that chronic hydrocephalus may alter the relationship between cerebrospinal fluid compliance and arterial inflow.

Summary: The prediction of fluid responsiveness in acutely ill patients is influenced by technical factors such as volume used during fluid loading and assessment methods for macrovascular flow, as well as clinical factors like positive end-expiratory pressure and norepinephrine dose. All these factors should be considered for individual intervention decisions.

Summary: Prediction of fluid responsiveness is crucial during shock resuscitation, with dynamic hemodynamic variables like stroke volume variation and pulse pressure variation showing better predictive value than static indices. Functional hemodynamic tests offer an alternative method for preload responsiveness prediction. Monitoring of cardiac output is essential regardless of the method used for evaluating the heart's response to changes in preload.

Summary: This study aimed to test the predictive value of Pulse Wave Transit Time (PWTT) for fluid responsiveness compared to established parameters Delta PP and FTc during major abdominal surgery. The results showed that PWTT had poor ability to predict fluid responsiveness.

Summary: Hemodynamic monitoring is crucial for assessing circulatory shock in patients. The development of bedside echocardiography, combined with noninvasive and minimally invasive technologies, has improved the ability to monitor and quantify cardiac output for effective hemodynamic management in acute care settings.
