Variant of the hydro-point ultrasound sign during the respiratory cycle obtained using a convex transducer placed in the eighth and ninth right intercostal space on the mid-axillary line (sagittal plane). A) End expiration: The diaphragm and liver are seen, together with an anechoic space between the diaphragm and chest wall (pleural effusion). Observe the “A” lines with no lung sliding in the uppermost intercostal space (pneumothorax). B) Start of inspiration: The “A” pattern starts to to shift downwards, erasing all subpleural ultrasound images. C) End inspiration: Only the pattern “A” is visible, with no lung sliding in the intercostal spaces. We interpret this sign as a barotrauma-induced air leak moving in sync with the respiratory cycle (Dynamic Hydro-point) (see Appendix B supplemental video).
