For your collection, we present another interesting set of ECGs from Paramedic Erik Testerman. They are from a 48 year old man who presented responsive only to painful stimuli, with deep, rapid (Kussmaul's) respirations. His blood glucose in the field read as "HIGH" - too high for the glucometer to register a number. He was treated with 3 large-bore IVs, 2 liters of NSS IV, O2. At the hospital, his blood glucose again registered as "HIGH" on the glucometer, arterial O2 was 90%, CO2 15 (low), pH 6.8 (acidotic), HCO3 -2 (depleted).
