To ARDSnet and Beyond: Part I

This podcast episode, the first of a two-part series on ARDS (Acute Respiratory Distress Syndrome), focuses on the identification and early management of ARDS using the ARDSnet protocol. The hosts discuss a fictional case of a 53-year-old male, named Phil, who develops ARDS post-surgery, and they use this case to illustrate key diagnostic criteria based on both the old AECC definition and the newer Berlin definition, emphasizing the importance of considering non-cardiogenic pulmonary edema. They explore the physiology of ARDS, its incidence, and the significance of early detection, highlighting that ARDS is often missed. The hosts then delve into the ARDSnet protocol, particularly the use of low tidal volume ventilation to prevent further lung injury, and address the potential complication of permissive hypercapnia, including how to adjust ventilator settings. The episode concludes with the initial steps of putting their example patient, Phil, on ARDSnet, setting the stage for the next episode, which will cover more advanced ARDS therapies.
