Lung-pulse signA-linesLung ultrasonography (LUS) is a diagnostic tool increasingly utilized in intensive care. Impedance difference between alveoli air and chest wall tissues impairs deep penetration of ultrasound signal, generating a horizontal hyperechoic artifact pattern, called A-lines. Atelectasis is...
Complete atelectasis can be immediately generated by selective intubation. A dynamic lung ultrasound sign can be described as the association of absent lung sliding with the perception of heart activity at the pleural line, a sign which was called “lung pulse.” We examined whether this sign be ...
A dynamic lung ultrasound sign can be described as the association of absent lung sliding with the perception of heart activity at the pleural line, a sign which was called "lung pulse." We examined whether this sign be used promptly to confirm complete atelectasis due to selective intubation....
In the absence of lung sliding the pattern observed is called the stratosphere sign, also called the bar code sign (Figure 9). The granular or sandy beach pattern below the pleural line is replaced by horizontal lines. There are two more dynamic findings, lung pulse (Lichtenstein et al., ...
the lung line. The sign of translobar consolidation is the tissue-like sign: it looks like liver. Both signs allow for 90% sensitivity (as explained) and 98% specificity [17]. Other signs are reserved for difficult cases [18]. The dynamic air bronchogram [17] and the lung pulse, which...
In pneumothorax, the absence of lung sliding will be associated with the presence of A-lines and the absence of lung pulse and B-lines or other vertical artifacts originating from the pleural line [11,40,49]. In M-mode, a pneumothorax is characterized by the “barcode sign” or “stratosp...

Atelectasis also shows the presence of a lung pulse, as described earlier. An inherent limitation of lung US is that it can only diag- nose consolidations that reach the pleural surface and lie in the intercostal window. In adults, the estimate of such missed consolidations is 8% [21]. ...
Lung ultrasound is a basic application of critical ultrasound, defined as a loop associating urgent diagnoses with immediate therapeutic decisions. It requires the mastery of ten signs: the bat sign (pleural line), lung sliding (yielding seashore sign),
“If we had an easy-to-implement clinical tool, like a blood test, that captured someone’s lung function trajectory at a single time point, it would enable earlier interventions which might, in the long run, improve lung health,” Kalhan added. ...
