Paediatric ultrasound and point of care ultrasound — branching viva

Emergency department: a febrile, grunting 8-month-old needs a bedside lung ultrasound to distinguish community-acquired pneumonia from bronchiolitis. The examiner asks how you would choose the probe and set the image, what artefact repertoire you would read, and how the BLUE protocol interprets the pattern — then branches to a 6-year-old unstable trauma victim with a positive FAST, to the sonographic signs of intussusception and pyloric stenosis, to ultrasound-guided difficult vascular access, and finally to a focus-assessed cardiac scan in the shocked child.
