Background: The multifactorial etiology of acute respiratory failure (ARF) often complicates
diagnosis at an early stage of clinical presentation. Despite being a common life-threatening
disorder, accurate and timely diagnosis is hindered by bad quality of bedside radiographs
and nonavailability of immediate computed tomography imaging. This study was an attempt
to evaluate the diagnostic accuracy of ultrasound in diagnosing ARF. Methods: This hospital-
based cross-sectional study investigated the underlying etiological factor in 130 patients …

Bedside lung ultrasound (LUS) is being adopted in ICUs, with a higher diagnostic accuracy
for consolidation, interstitial syndrome, pleural effusion, and pneumothorax when compared
with chest radiography (CXR). Compare the diagnostic performance of LUS and CXR for the
detection of pathologic abnormalities in critically ill patients in ICU, using thoracic computed
tomography (CT) as a gold standard. Prospective and descriptive single-center study. Prior
to CT, we performed bedside LUS and CXR, evaluating hemithoraces and characterized …
