“…However, opposite to BLA, A-lines have no pathologic meaning. For this reason, even without a clear visualization of A-lines, it is decisive a pattern with no lung sliding and no BLA to identify a pneumothorax [77]. Also, in a condition of lung sliding without BLA, even in the absence of clearly visible A-lines, it is possible to rule out an interstitial syndrome.…”

IntroductionIn years gone by examination of patients with pulmonary disorders rested essentially on a clinician's bedside physical examination, of auscultation and percussion, complimented with blood gas analysis and X-ray imaging. Lung ultrasound has emerged into this context as a real-time bedside procedure, delivering information relevant to the clinician's differential diagnosis. A large part of sonographic lung examination involves the interpretation of artefacts, thus knowledge of the origin of typical artefacts is important. Although indirect sonographic signs, nonetheless reliable conclusions on the condition of the lung can be inferred. Particularly the of quantity and distribution of B-lines can establish important assessment of the cause and degree of fluid load within the interstitium.All focused ultrasound investigations, including bedside lung ultrasound, allow symptom evaluation considering multiple organ-systems yet with minimal time delay. Such integration of imaging with clinical assessment and treatment is called Point-of-Care Ultrasound (POCUS) and should be understood as an extension of the physical examination. POCUS offers a unique but crucial role, integrating clinical and other imaging findings, including cardiac ultrasound (echocardiography), chest radiography, and computed tomography (CT) scans is crucial, which alone may lack the required accuracy.The emergence of differences in approach to lung sonography, technique and nomenclature, provided the AbstractThe science of lung ultrasound has grown tremendously over the last two decades and lung ultrasound has not only entered the mainstream of point of care ultrasound but has become a dominant topic. Understanding lung ultrasound signs and artifacts is critical to being able to correlate findings with actual pathology and normal anatomy and physiology. Investigators have described multiple lung ultrasound artifacts and findings and it is important to understand both the physics and anatomic basis behind them. Additionally, ultrasound machine use and transducer selection can significantly affect results obtained on patient during an examination and the provider must carefully choose the correct settings. This manuscript describes the state of the art in ultrasound artifact recognition and correlation as well as management of ultrasound technology to optimize diagnostic success.Keywords: ultrasound, lung, artifacts, pathology, guidelines [2,[11][12][13][14][15] we discuss the prominent role of the particular artefacts of lung sonography answering differential-diagnostic questions in patients with cardio-pulmonary diseases.

“…1,2 A diagnosis of pulmonary embolism was considered in this patient because of the history of deep venous thrombosis; however, within a minute, bedside ultrasonography revealed the presence of hypovolemia from a hemorrhagic shock secondary to a left-sided hemothorax. The diagnosis of hypovolemia is challenging and is discussed in more detail.…”

“…10 Although lung ultrasound has been embraced as a useful technique in emergency medicine, it is still not widely taught in our anesthesiology or critical care training programs. Technical details on the use of this technique can be found in key review articles 11,12 and are beyond the scope of this editorial. Nevertheless, understanding the mechanism of hypoxemia helps recognize the limitations of lung ultrasound.…”

“…10 Bien que l'utilité de l'échographie pulmonaire ne soit plus à démontrer en médecine d'urgence, elle n'est que peu enseignée dans nos programmes de formation d'anesthésiologie ou de soins intensifs. Les détails concernant l'utilisation de cette technique sont disponibles dans deux articles de synthèse clés 11,12 et dépassent le propos de cet éditorial. Toutefois, en comprenant les mécanismes sous-jacents à l'hypoxémie, il est plus aisé de prendre conscience des limites de l'échographie pulmonaire.…”
