Lung ultrasound in heart failure: Lessons from re-analysis of Lung Ultrasound 2011 database.

: In the setting of patients presenting with shortness of breath to an Emergency Department a simple lung ultrasound protocol aimed at detecting pulmonary oedema has been shown to have diagnostic accuracy of 85%. This article reviews data from the original study, in an attempt to determine whether adjusting the protocol and/or interpretive criteria would improve results. : A large lung ultrasound project provided the dataset.

Limited lung ultrasound protocol in elderly patients with breathlessness; agreement between bedside interpretation and stored images as acquired by experienced and inexperienced sonologists.

: Bedside lung ultrasound is increasingly performed in the Emergency Department to assess dyspnoeic patients. Quantifying the number of B-lines (a vertical short path reverberation artefact caused by the presence of interstitial fluid) can help clinicians differentiate 'wet lung' - pulmonary oedema, from 'dry lung' - not pulmonary oedema. The aim of this study was to determine inter-rater agreement for this simple bedside investigation, comparing relative ultrasound novices with more experienced personnel.
