Dyspnea is one of the most distressing situations for the patient . Emergency cases do not always present in conditions that are ideal for immediate diagnosis, which sometimes compromises outcome. Physical examination, laboratory findings and radiography are imperfect, resulting in a need for sophisticated test results that delay management.~Lung ultrasonography is becoming a standard tool in critical cases in the ED.~the investigators aim to perform ultrasonography on consecutive patients admitted to the ICU with dyspnea, comparing lung ultrasonography results on initial presentation with the final diagnosis by the nurses.~Three items were assessed: artifacts (horizontal A lines or vertical B lines indicating interstitial syndrome), lung sliding, and alveolar consolidation and/or pleural effusion, these items were grouped to assess ultrasound profiles.~the study aimed to evaluate the accuracy and reproducibility of B-lines testing assessed by emergency nurses after 12-h training in the diagnosis of HF in patients admitted to the emergency department with acute dyspnea.
This study assesses the potential of lung ultrasonography to diagnose heart failure.
