Brief summary

Fluid responsiveness refers to the ability of the left ventricle to significantly increase stroke volume following fluid administration, and its assessment is critical in managing acute circulatory failure while avoiding fluid overload.Infraclavicular axillary vein collapsibility index is a substitute for inferior vena cava collapsibility index in assessment for the need of fluid resuscitation in spontaneously breathing sepsis related acute circulatory failure patients.

Design outcomes

Primary

MeasureTime frameDescription
The infraclavicular axillary vein collapsibility index changes in response to fluid challenge.Fluid challenge over 10 min time period.The infraclavicular axillary vein collapsibility index changes in response to fluid challenge. A collapsibility index greater than fifty percent in spontaneously breathing patients is commonly associated with a right atrial pressure between zero and five millimeters of mercury.
