We all know “shark fin” and keep it above 10 during CPR, but when was the last time you were taught or used capnography to evaluate your patient’s perfusion status? Do you titrate your interventions using capnography? This interactive case-based session will take a deep dive into capnography’s critical use in evaluating and trending the patient's perfusion status at all times of care. We will go through case-based scenarios correlating various treatments and their effects on the patient and EtCO2.
