Explore standard and emerging techniques in time-based and volumetric capnography in this comprehensive 41-minute video lecture by Dr. Ira Cheifetz, Chief of Critical Care at Duke Children's Hospital. Gain insights into ventilation-perfusion relationships and their importance in critical care. Learn about different types of capnography devices, normal capnogram interpretation, and the availability of capnography on inpatient wards. Discover the significance of end-tidal CO2 (EtCO2) in CPR provider fatigue and return of spontaneous circulation. Delve into volumetric capnography, including single breath CO2 waveforms, normal CO2 elimination, and factors influencing it. Understand how CO2 can predict fluid responsiveness and explore concepts such as physiologic dead space, its measurement, and its relation to extubation success and ARDS mortality. Compare alveolar dead space fraction with Vd/Vt ratio for a comprehensive understanding of capnography as a clinical tool in pediatric critical care. Read more
