Elevated central venous pressure is associated with increased mortality . . . Background The association of central venous pressure (CVP) and mortality and acute kidney injury (AKI) in critically ill adult patients remains unclear We performed a meta-analysis to determine whether elevated CVP is associated with increased mortality and AKI in critically ill adult patients Methods We searched PubMed and Embase through June 2019 to identify studies that investigated the

Cardiac output and CVP monitoring… to guide fluid removal We read with interest the recently published position papers on central venous pressure (CVP) [1] and cardiac output (CO) [2] monitoring in critically ill patients and wish to further comment on their potential benefit Haemodynamic monitoring is usually considered for haemodynamic support guidance during the early phase of shock We would like, however, to emphasize the role of CVP and CO
The elusive relationship between cardiac filling and fluid . . . The Doppler starling curve The four hemodynamic phenotypes (1–4) are generated by combinations of normal and low stroke volume on the y -axis and normal or congested venous measures on the x -axis The family of Starling curves (dotted lines) shows that a patient can have normal venous measures and be responsive (patient A, green) or unresponsive (patient B, red) If a population is studied
Central venous pressure measurement is associated with improved . . . A retrospective study con-ducted by Legrand declared that a high CVP value within the first 24 h of admission was associated with the risk of developing new or persistent acute kidney in-jury (AKI) [6], and limiting CVP in liver surgery is asso-ciated with a decreased risk of bleeding and improved perioperative outcomes [7]
Central venous pressure monitoring and mortality: What was neglected . . . We are interested in the recent published article about the association between central venous pressure (CVP) monitoring and mortality for ICU patients with sepsis [1] The study provides new insights into this traditional monitoring However, an important factor might make the study more convincing if it had been taken into account
Trendelenburg position is a reasonable alternative to passive leg . . . Trendelenburg position initiated from the reverse Trendelenburg position Compared with baseline-1, the reverse Trendelenburg position resulted in a significant decrease in SAP, SVI, CCI, and CVP, and a significant increase in PPV and SVV, while HR remained unchanged (Table 3)
Cardiac output monitoring: an integrative perspective Various cardiac output monitoring devices require a central venous line for calibration of the system Thus, central venous pressure (CVP) is briefly reviewed here CVP is traditionally assessed as an estimate of cardiac preload since true preload, which is defined as end-diastolic myocardial fiber tension, cannot be measured at the bedside
Comments on “Right ventricular failure in septic shock . . . The authors defined right ventricular failure as the association of RV dilatation (RV LVEDA < 0 6) and increased central venous pressure (CVP ≥ 8 mmHg) They showed that this definition of RV failure is associated with lack of fluid responsiveness Therefore, CVP could be used as an additional measurement to RV dilatation to discriminate between patients with and without congestive RV
