Capnography as a Clinical Tool by Ira Cheifetz, MD, FCCM, FAARC for OPENPediatrics

This course explains standard and emerging time-based and volumetric capnography techniques for critically ill patients. It covers CO₂ waveforms, physiologic dead-space measurement, and the use of capnography to assess resuscitation, fluid responsiveness, extubation, and ARDS outcomes.
