#1: Bubble Time – A New, Simple Way to Detect RV Dysfunction
Spoon Feed
By agitating and injecting a saline flush into an IV catheter, right ventricular (RV) dysfunction was identified when bubbles were cleared from the RV at a time of ≥ 40 seconds with high sensitivity. It was ruled out as well with good specificity, with a bubble time < 40 seconds.

#2: Ultrasound + Pediatric Appendicitis Risk Calculator = Rule Out?
Spoon Feed
This was a single center retrospective study at a tertiary pediatric ED of patients with suspected pediatric appendicitis. The authors found that combining a low pediatric Appendicitis Risk Calculator (pARC) result with a nondiagnostic ultrasound results in a high negative predictive value for appendicitis.
