Volpicelli G, Mussa A, Garofalo G, et al.: Bedside lung ultrasound in the assessment of alveolar-interstitial syndrome. Am J Emerg Med 2006, 24: 689–696. 10.1016/j.ajem.2006.02.013 B-lines are not observed in pneumothorax, as they are seen only at pleura/tissue acoustic interface (for which the apposition of both pleural layers is required, whereas in pneumothorax both layers are separated by air in between them). Occasional B-lines (up to two) can be seen in normal lungs (commonly at the bases). They are considered significant if three or more B-lines are seen in a single image between two ribs.

In the 2012 film The Dark Knight Rises, the rusted remains of the destroyed Bat-Signal are still atop police headquarters. However, at the end of the film, with Batman declared dead, Gordon sees a restored Bat-Signal, providing hope that Batman has survived. (The signal itself is never used once in the film, however, making it the only live-action film about Batman where this occurs.)

A hypovolemic mechanism will benefit from fluid therapy, with corrections of the circulatory failure, and unchanged A-profile.

With your interest in volunteer opportunities, we think you'd be most interested in learning how to volunteer with POCUS. On the 1992 television show Batman: The Animated Series, the signal is introduced in the episode "The Cape and Cowl Conspiracy", though a makeshift signal was used earlier in " Joker's Favor". In 2004's The Batman, Gordon invents it to summon Batman in "Night in the City", although the signal is also alluded to in an earlier episode. Lichtenstein D: FALLS-protocol.
