Hyponatremia, defined as serum sodium concentration of less than 135 mEq/L, is a common electrolyte disorder observed in hospitalized patients. Its diagnosis is clinically relevant due to the associated risk of increased morbidity and mortality. A critical step in managing hyponatremia is the correct assessment of the patient’s volume status (hypovolemic, euvolemic, or hypervolemic), which guides therapeutic decisions. However, current diagnostic approaches, which are based on clinical evaluation, laboratory data, and static ultrasound assessments, often lack sensitivity and specificity, leading to frequent misclassifications. This thesis explores the integration of a novel software solution, developed by VIPER s.r.l, into current diagnostic methods for assessing volume status.
