End tidal capnography (ETCO₂) is one of the most important tools in emergency medicine, anesthesia, and critical care. In this episode, we break down normal and abnormal capnography waveforms, explain the physiology behind each pattern, and show you how to apply ETCO₂ in real clinical scenarios.
📌 What’s covered in this video: Normal ETCO₂ waveform and interpretation. Obstructive patterns (bronchospasm, airway obstruction). The “curare cleft” and inadequate neuromuscular blockade. Hyperventilation vs hypoventilation on waveform analysis. Capnography in cardiac arrest: ROSC detection & quality of CPR. Clinical pearls for the ED, ICU, and OR.
