• Oxygen Extraction Ratio (O₂ ER) in the PICU

  Welcome to another exciting episode of PICU Doc on Call! Today, we're diving deep into the world of pediatric critical care with our expert hosts, Dr. Rahul Damania, Dr. Pradip Kamat, and Dr. Monica Gray. Get ready to unravel the mysteries of the oxygen extraction ratio (O2ER) and its pivotal role in managing pediatric acute respiratory distress syndrome (ARDS) and multi-organ dysfunction.Picture this: a seven-year-old girl battling severe pneumonia that spirals into ARDS and septic shock.
