In a study conducted in a 10-bed pediatric intensive care unit (PICU) in Japan, the effectiveness of chest X-rays (CXR), chest computed tomography (CCT), and lung ultrasound (LUS) in diagnosing respiratory failure in children were compared. Among seven children, LUS proved safe and useful, showing comparable results to CCT for conditions like interstitial pneumonia, pulmonary edema, atelectasis, pneumonia, and pleural effusion. CXR was less effective, particularly for qualitative assessments. LUS demonstrated potential as a reliable tool for evaluating respiratory issues in the PICU, being both safe and accessible.
