In the article “Lung Ultrasound in Emergency and Critically Ill Patients: Number of Supervised Exams to Reach Basic Competence” published in the April 2020 issue, there is an error in the Methods section. In the third paragraph under “Lung Ultrasound Curriculum and the APECHO Study” on page 902, the sentence “… (3) interstitial syndrome, defined as the presence of more than two spaced B lines or coalescent B lines, detected in a limited portion of the intercostal space and issued from the pleural line or subpleural consolidations of at least 5 mm;…” should be replaced by “… (3) interstitial syndrome, defined as the presence of more than two spaced B lines;…”.
The authors regret the error. The online version and PDF of the article have been corrected.
