“…31,32 Four intercostal spaces are examined in the right side, and 3 in the left side, and the presence of coalescent vertical B lines is quoted 10 B lines. The lung ultrasound score is significantly correlated to extravascular lung water measured by gravimetry, 33 the indicator dilution method, 23 or computed tomography. 26 In patients with ARDS and/or pneumonia, consolidated lung areas predominating in dependent lung regions coexist with interstitial and alveolar edema present in anterior and lateral lung regions.…”

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.

“…Indeed, in an animal model with acute lung injury induced by oleic acid, a strong correlation was found between the number of Blines and the wet-to-dry ratio of the lung tissue. 25 The Blines respond very quickly to changes in EVLW and thus allow real-time follow-up of fluid or diuretic therapy. 26 In our experience, left-sided B-lines are present on the preprocedure TELU exam in a significant proportion of cardiac surgery cases.…”

Background Acute deterioration in respiratory status commonly occurs in patients who cannot be transported for imaging studies, particularly during surgical procedures and in critical care settings. Transthoracic lung ultrasonography has been developed to allow rapid diagnosis of respiratory conditions at the bedside. Nevertheless, the thorax is not always accessible, especially in the perioperative setting. Transesophageal lung ultrasonography (TELU) can be used to circumvent this problem. Purpose The aim of this narrative review is to provide a complete description of the TELU technique by summarizing the existing literature on the subject and describing our own experience that extrapolates from transthoracic lung ultrasonography. Principal findings The use of TELU can provide point-ofcare real-time information for quickly establishing the etiology of acute hypoxemia. The transesophageal probe is placed in close proximity to the posterior regions of the lungs where lung consolidation and pleural effusions are most often seen; however, most of the artefacts relied on by transthoracic ultrasound have yet to be validated with TELU. Moreover, the relative invasiveness of TELU compared with transthoracic ultrasonography may limit its use to specific situations when the probe is already in place, as during cardiac anesthesia or when the anterior thorax is inaccessible. The main advantage of TELU may lie in the ability to integrate both cardiac and pulmonary assessments in one single examination. Conclusion Anesthesiologists and intensivists who already use transesophageal echocardiography on a regular basis should consider adding TELU to their clinical assessment of hypoxemia and related pulmonary pathologies. Nevertheless, the literature specifically supporting TELU is relatively limited, and further validation studies are needed. RésuméContexte Des détériorations aiguës de l'état respiratoire de patients qui ne peuvent être transportés pour des examens d'imagerie sont fréquentes, particulièrement lors d'interventions chirurgicales ainsi que dans le contexte des soins intensifs. L'échographie pulmonaire transthoracique a été mise au point afin de permettre de diagnostiquer rapidement la cause d'une détérioration respiratoire au chevet du patient. Or, le thorax n'est pas toujours accessible, particulièrement dans un contexte périopératoire.L'échographie transoesophagienne pulmonaire (ETOP) peut alors être utilisée pour pallier ce problème.
