This week Dr. Diaz starts off with a challenging case of massive upper GI bleed managed with balloon tamponade. We then moved into a case follow-up with profound electrical storm and recurrent ventricular arrhythmias secondary to a STEMI. Following this, we took a deep dive into waveform capnography regarding normal physiology and alterations with lung pathology with Dr. Wilson. Next, we had an exciting CPC showdown where Dr. Bryant successfully diagnosed Dr. Haffner’s case of valproic acid toxicity presenting with hyperammonemic encephalopathy. We closed with Dr. Wosiski-Kuhn outlining the difficulty of intubation in a patient with DKA and severe metabolic acidosis.
