“…In the literature, alternative experimental models able to generate B-lines have been reported. Differently than the model presented in this study these models were based on gelatin phantoms containing large air bubbles (mm size) obtained by manual injection of air by means of a syringe 21 , sponges 22 , 23 and foams 24 .…”

B-lines are ultrasound-imaging artifacts, which correlate with several lung-pathologies. However, their understanding and characterization is still largely incomplete. To further study B-lines, lung-phantoms were developed by trapping a layer of microbubbles in tissue-mimicking gel. To simulate the alveolar size reduction typical of various pathologies, 170 and 80 µm bubbles were used for phantom-type 1 and 2, respectively. A normal alveolar diameter is approximately 280 µm. A LA332 linear-array connected to the ULA-OP platform was used for imaging. Standard ultrasound (US) imaging at 4.5 MHz was performed. Subsequently, a multi-frequency approach was used where images were sequentially generated using orthogonal sub-bands centered at different frequencies (3, 4, 5, and 6 MHz). Results show that B-lines appear predominantly with phantom-type 2. Moreover, the multi-frequency approach revealed that the B-lines originate from a specific portion of the US spectrum. These results can give rise to significant clinical applications since, if further confirmed by extensive in-vivo studies, the native frequency of B-lines could provide a quantitative-measure of the state of the lung.

“…Hand ultrasounds were compared to simulated normal lung or pneumothorax models (presence or absence of lung sliding)[ 45 , 46 ]. A gelatine-based model that simulated a normal lung or pneumothorax, pulmonary oedema, or pneumonia (B-lines), and pleural effusion was also tested[ 28 ]. Another gelatine-based model that simulated the diaphragm, pleural fluid, and lung parenchyma was used in order to train for thoracentesis[ 30 ].…”

“…Another gelatine-based model that simulated the diaphragm, pleural fluid, and lung parenchyma was used in order to train for thoracentesis[ 30 ]. Sponge and dressing materials in both the hand and gelatine simulators generated A-lines and B-lines[ 16 , 28 , 47 ].…”

“…This is because the parallel bony structure of metacarpal bone is similar to ribs, the soft tissue between the metacarpal bones is similar to the intercostal space, the interface between air and skin is similar to the lung and pleura interface, and similar to the soft tissue of the anterior chest wall[ 16 , 45 ]. The gelatine model, involving 20 g of gelatine, 60 mL of water, and 1 g of agar used as an additive, was used to represent the thoracic wall[ 28 ]. Tree branches were used to make the simulator represent ribs[ 28 ].…”

Point-of-care ultrasound (POCUS) is a powerful diagnostic tool and provides treatment guidelines in acute critical settings. However, the limitation of using POCUS is operator dependent. Appropriate and validated training for acquiring and using skills in practice must be conducted before using POCUS in clinical settings in order to keep patients safe. Simulation education models have been introduced as a way to solve and overcome these concerns. However, the commercial simulator with sufficiently secured fidelity is expensive and not always available. This review focused on the inexpensive and easily made simulators for education on POCUS in critical specific situations related to the airway, breathing, circulation, and disability. We introduced the simulators that used non-infectious materials, with easily transportable features, and that had a sonographic appearance reproducibility similar to human tissue. We also introduced the recipe of each simulator in two parts: Materials surrounding disease simulators (surrounding materials) and specific disease simulators themselves (target simulators). This review article covered the following: endotracheal or oesophageal intubation, lung (A-lines, B-lines, lung sliding, and pleural effusions such as hemothorax), central vein access, pericardial fluid (cardiac tamponade), the structure related to the eyes, soft tissue abscess, nerve (regional nerve block), and skull fracture simulators.
