Infraclavicular Axillary Vein Collapsibility Index as a Predictor of Fluid Responsiveness

Infraclavicular Axillary Vein Collapsibility Index as a Predictor of Fluid Responsiveness in Spontaneously Breathing Patients in Sepsis-related Acute Circulatory Failure: a Prospective Observational Study

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.

Inclusion Criteria:

• Adult patients ≥18 years.
• Patients with sepsis must meet at least two or more criteria of systemic inflammatory response syndrome (SIRS).
• Spontaneously breathing patients.
• Clinical signs of acute circulatory failure.

Exclusion Criteria:

• Patients below the age of 18 years.
• Mechanically ventilated patients
