Clinical teaching and practical ideas for your next study session.
Infant Cardiac Output Is Heart-Rate Dependent—But Not Heart-Rate Only
A falling heart rate can mean recovery—or loss of compensation. Learn how to combine developmental cardiac physiology with perfusion, rhythm, and resuscitation context to interpret the change correctly.
CoNS-Positive Blood Culture in a Child With a Central Line: Salvage or Remove?
A stable child with a single CoNS-positive culture needs paired source assessment before a line decision. Learn to distinguish contamination, intraluminal colonization, CLABSI surveillance, and true CRBSI, then match salvage or removal and treatment duration to culture clearance.
Severe PPHN on Echocardiography: Read the Pressure Pattern
Severe persistent pulmonary hypertension of the newborn is best recognized as a linked pressure-and-flow pattern, not a single echocardiographic measurement. Learn how RV pressure, septal geometry, shunt direction, and ventricular function fit together.
