JC: POCUS Learning Curve & Intestinal Foreign Bodies

This weeks readings:

Chenkin et al. Defining the learning curve of point‑of‑care ultrasound for confirming endotracheal tube placement by emergency physicians. Crit Ultrasound J (2015) 7:14 DOI 10.1186/s13089-015-0031-7 [Attached]


  1. Describe the process of learning that is laid out in the article. What learning theory does this fall into.
  2. Does 10 correct interpretations mean that someone is proficient in image interpretation of Intubation placement ultrasounds? 
    • How would we this apply to other applications?
    • What would be the ideal method of determining this threshold number?
  3. How would a larger sample /threshold for proficiency have yielded different results (as mentioned in the discussion?)

  1. How were these cases influenced by the use of POCUS?
  2. How might we use POCUS to help us in the FB ingestion?
  3. What is the value of recognizing normal bowel?
