Renal fractional excretion of sodium in relation to arterial blood gas and spirometric parameters in chronic obstructive pulmonary disease

ABSTRACT

Introduction: Arterial gas derangement could change urinary sodium excretion in Chronic Obstructive Pulmonary Disease [COPD] patients. There are very few and conflicting data in regards to the measurement of fractional excretion of sodium in COPD patients. The main aim of this study was to assess the relationship between renal fractional excretion of sodium [FeNa] with arterial blood gas and spirometric parameters in COPD
