Correlation Between Lung Injury Score, PvO2/FiO2 Ratio and Oxidative Stress Markers in Tracheal Aspirate Samples in Intubated Infant Patients During Chest Physical Therapy

Abstract

Background: Pneumonia presents high oxidative stress, which directly affects the lung injury and oxygenation status. Evidence has shown the correlation of oxidative stress markers in tracheal aspirates (TA) in infant patients, however, not before or after chest physical therapy (CPT).
