It’s a dark night when a red code arrive at the ED by ambulance. Paramedics tell you: “called for acute dyspnoea, I think it’s a COPD exacerbation, he is wheezing, I gave him bronchodilators and steroids, but he is worsening”. He has a history of COPD and hypertension. He presents sweaty, dyspneic, arterial pressure is high (220/110). Physical examination is normal except for wheezing.What is the LR of clinical signs in the diagnosis of pulmonary oedema?
Conclusion
The absence of pulmonary rales (sensitivity 0.60; specificity 0,78; LR + 2,73 LR – 0,51) and the presence of wheezing (sensitivity 0.22; specificity 0,58; LR+ 0,52 LR – 1,34) decreased the likelihood of heart failure insufficently to rule out a pulmonary oedema in a patient presenting with acute dyspnoea.
In acute setting you might need something more than your stetoscope
….but is it x ray?
