Prediction of fluid responsiveness. What’s new?

Annals of Intensive Care, 2022
Although the administration of fluid is the first treatment considered in almost all cases of circulatory failure, this therapeutic option poses two essential problems: the increase in cardiac output induced by a bolus of fluid is inconstant, and the ...

Tidal volume challenge to predict fluid responsiveness in the operating room

European Journal of Anaesthesiology, 2019
Pulse pressure variation (PPV) and stroke volume variation (SVV) do not predict fluid responsiveness when using a protective ventilation strategy: the use of functional haemodynamic tests can be useful to overcome this limitation.We tested the use of a tidal volume challenge (VTC), during 6 ml kg [predicted body weight (PBW)] ventilation, and the end ...

How I personalize fluid therapy in septic shock?

Critical Care, 2023
During septic shock, fluid therapy is aimed at increasing cardiac output and improving tissue oxygenation, but it poses two problems: it has inconsistent and transient efficacy, and it has many well-documented deleterious effects.

Challenges encountered in employing a low tidal volume ventilation strategy in patients at risk of ARDS [PDF]

Intensive Care Medicine Experimental, 2015
Ventilator strategies that use tidal volumes (TVs) limited to 6 ml/kg IBW (ideal body weight) have been shown to reduce mortality in patients with ARDS (acute respiratory distress syndrome). [1] It is suggested that using these same low tidal volumes in other critically ill patients may reduce the progression to ARDS. [2, 3] An initial audit in the ICU

Ventilatory responses during and following hypercapnic gas challenge are impaired in male but not female endothelial NOS knock-out mice

Scientific Reports, 2021
The roles of endothelial nitric oxide synthase (eNOS) in the ventilatory responses during and after a hypercapnic gas challenge (HCC, 5% CO2, 21% O2, 74% N2) were assessed in freely-moving female and male wild-type (WT) C57BL6 mice and eNOS knock-out ...

Tidal Volume Challenge to Reliably Predict Fluid Responsiveness in Critically Ill Patients – An Interim Analysis [PDF]

Indian J Crit Care Med
INTRODUCTION: Fluid administration is the first line of treatment in patients with acute circulatory failure. Although hypovolemia leading to organ dysfunction and death, excessive fluid loading is associated with increased complications, mortality, and length of ICU stay(1).

Relationship Between Cerebrovascular Reactivity and Cognition Among People With Risk of Cognitive Decline

Frontiers in Physiology, 2021
Vascular risk factors (e.g., obesity and hypertension) are associated with cerebral small vessel disease, Alzheimer’s disease (AD) pathology, and dementia.

Assessment of Fluid Responsiveness After Tidal Volume Challenge During Pressure-Controlled Ventilation Volume Guaranteed: An observational study [PDF]

, 2020
Abstract Background: The reliability of pulse pressure variation (PPV) and stroke volume variation (SVV) to predict fluid responsiveness have not previously been established when using pressure-controlled ventilation-volume guaranteed (PCV-VG) mode.

End-Expiratory Occlusion Test and Tidal Volume Challenge Test for Evaluating Fluid Responsiveness in Severe Traumatic Brain Injury, Septic Shock, and Acute Respiratory Distress Syndrome. [PDF]

Cureus
Fluid management in critically ill patients, particularly those with severe traumatic brain injury (TBI), septic shock, and acute respiratory distress syndrome (ARDS), presents a complex and multifaceted challenge. Dynamic tests such as the end-expiratory occlusion (EEO) test and tidal volume challenge (TVC) test are commonly used to assess fluid ...
