Prospective outcome prediction and volume status assessment are difficult tasks in the acute care environment. Rapidly available, non-invasive, bioimpedance vector analysis (BIVA) may offer objective measures to improve clinical decision-making and predict outcomes. Performed by the placement of bipolar electrodes at the wrist and ankle, data is graphically displayed such that short-term morality risk and volume status can be accurately quantified. BIVA is able to provide indices of general…

Bioimpedance Vectorial Analyses in Cardiorenal Syndrome
TLDR
In patients with end-stage kidney disease, an accurate evaluation of volume status changes during hemodialysis (HD) is required for defining the goal for fluid removal, and BIVA has proven to be reliable in identifying the volume of fluid removed during HD allowing a safer dialysis treatment.
Assessment of intravascular volume status and volume responsiveness in critically ill patients.
TLDR
This review highlights both static and dynamic methods that can be utilized to help in the assessment of volume status, as well as highlighting the negative impact of either inadequate or overaggressive fluid therapy.
Use of Multifrequency Bioimpedance Analysis in Male Patients with Acute Kidney Injury Who Are Undergoing Continuous Veno-Venous Hemodiafiltration
TLDR
Fuid overload is a well-known predictor of mortality in patients with acute kidney injury (AKI), and Multifrequency bioimpedance analysis (MF-BIA)-defined excess TBW/H2 and ICW/h2 are independently associated with higher in-hospital mortality in male patients with AKI undergoing CVVHDF.
Bioelectrical impedance vector analysis in critically ill patients: a prospective, clinician-blinded investigation
TLDR
BIVA is feasible in critically ill patients and its validity is supported by the observed characteristics of patients with different degrees of BIVA hydration upon admission and by different fluid management of such patients by blinded clinicians, providing the rational basis for studies of BivA-assisted fluid management in ICU patients.
Differences in capillary recruitment between cardiac surgery and septic patients after fluid resuscitation.
Bioimpedance vector pattern in head and neck squamous cell carcinoma.
TLDR
Monitoring vector displacement trajectory toward the reference target vector position may represent useful feedback in support therapy planning of individual patients before surgery in patients with head and neck cancer in order to reduce post-operational complications.
Phase angle is related to outcome after ICU admission; an observational study.
Direct markers of organ perfusion to guide fluid therapy: when to start, when to stop.
Bioimpedance vector pattern in women with breast cancer detected by bioelectric impedance vector analysis. Preliminary observations.
TLDR
The results observed in the presented study provide valuable information on the nutritional status of the patient prior to surgery and can allow for early corrective intervention in patients with breast cancer.
Comparison of Bioimpedance and Clinical Methods for Dry Weight Prediction in Maintenance Hemodialysis Patients
TLDR
The BIA equations have better consistency with clinical dry weight in MHD patients, compared with the body composition spectroscopy and the BCS methods.

Bench to bedside: electrophysiologic and clinical principles of noninvasive hemodynamic monitoring using impedance cardiography.
TLDR
Impedance cardiography (ICG) is a noninvasive method of obtaining continuous measurements of hemodynamic data such as cardiac output that requires little technical expertise and is important for the possible role of this technology in the practice of emergency medicine.

TLDR
The phase angle alpha was the best single predictive factor for survival among all 12 parameters (comparison of the respective Cox models with the likelihood ratio test) and the ECM/BCM ratio, Xc, BCM, serum cholesterol, number of CD4+ cells, and serum albumin had significant prognostic influence on survival.
Bioelectrical impedance phase angle as a prognostic indicator in advanced pancreatic cancer.
TLDR
It is demonstrated that phase angle is a strong prognostic indicator in advanced pancreatic cancer and similar studies in other cancer settings with larger sample sizes are needed to further validate the prognostic significance of the phase angle.

TLDR
Bioelectrical impedance analysis allows an easier evaluation of body composition and this might be particularly useful to stratify the severity of HF.
A new method for monitoring body fluid variation by bioimpedance analysis: the RXc graph.
TLDR
A new approach is presented for routine monitoring of the body fluid variation in the single patient, without making any assumption on body composition, based on the analysis of the bivariate distribution of the impedance vector in a healthy population and in patients with increased body weight, due to either obesity or edema from renal diseases.
