• Idea that putting together the different exams allows you to answer your question
– Why is this patient dyspneic?
• Lung US + Cardiac US + DVT exam
Trang 5Putting things together
• Basic echo findings (size, function, etc)
Trang 6• Qualitative

Blue Protocol
• 260 pts with respiratory failure – had a
diagnosis categorized by US findings alone
compared to ultimate “gold standard” diagnosis
• Correctly categorized Dx in > 90% of cases
• Differentiated asthma/COPD; PE; pneumonia; pulmonary edema; PNTX
Lichtnestein, D Chest 2008; 134: 117
Trang 9– 139 consecutive pts with acute respiratory failure
– US heart, lungs and deep veins
– 96% could have exam completed
– 14% found condition missed with primary assessment – Using audit as gold standard:
• SN 100%; SP 93.3%; PPV 76.7% and NPV 100%
