Aims
• To understand how to identify BLUE points
• How to use the BLUE protocol to make a diagnosis

Background
• Physical examination and CXR have a poor diagnostic
accuracy for acute respiratory failure (ARF).
• CT is impractical for most cases of ARF.
• Ultrasound has diagnostic accuracy approaching CT scan

Summary
• Observational study of 260 patients with acute respiratory
failure.
• 31% pneumonia, 24% pulmonary oedema, 18% COPD,
12% asthma, 8% PE, 3% pneumothorax.
• Specificity for each disease with US >90%.
• Diagnostic accuracy 90.5%.

• A normal PLAPS will show sliding and A-lines.
• An abnormal PLAPS means consolidation and/or an
effusion.

• Any patient with acute respiratory failure.
• Do as part of the physical exam before other tests.
• 90.5% accuracy is from US alone. Combination with the
history and other investigations will improve accuracy to
close to 100%.
