ICUedu is an educational podcast series focused on emergency critical care fundamentals, created and hosted by Dr. Sara Crager, an emergency physician and intensivist.
With clinical appointments at UCLA and Antelope Valley Medical Center, Sara brings a wealth of experience to the series, aiming to demystify complex critical care concepts through concise, high-yield discussions.

This short episode defines Strong Ion Difference (SID) and explains how fluid composition influences acid-base balance in critical care. Key teaching point: SID is a better predictor of acid-base effect than bicarbonate or pH alone.

This episode reframes fluid choice in acidosis and DKA—explaining why normal saline can worsen acidosis and why LR often gets unfairly blamed for its potassium content. Key teaching point: Use LR for most DKA and acidosis cases.

Learn to assess compensation in DKA with one glance—no formulas needed. This episode redefines how we judge physiologic reserve and acid-base status. Key teaching point: Compensation stops at pH ~7.10—no more room.

Fixing DKA is about more than insulin—it starts with potassium. This episode walks through real-world repletion strategies and why magnesium matters too. Key teaching point: Never start insulin if K+ <3.3.

This episode explores why DKA patients remain acidotic after resolution—including hyperchloremia from NS and loss of potential bicarb via ketoacid excretion. Key teaching point: Closed anion gap ≠ resolved acidosis.

This episode walks through how to safely intubate a profoundly acidotic patient without causing lethal decompensation. Key teaching point: BiPAP buys time and helps ventilation before intubation.
