SCCM Resource Library-Different Approaches to Optimizing PEEP

Video Transcription

Video Summary

The video transcript is divided into three parts, with each presenter discussing different aspects of Positive End Expiratory Pressure (PEEP) in critical care. The first presenter, John Marini, talks about the physiological effects of PEEP on lung volume and recruitment, as well as the potential for harm from excessive PEEP levels. He emphasizes the heterogeneity of lung units in patients with Acute Respiratory Distress Syndrome (ARDS) and the need to find an optimal PEEP level that balances recruitment and harm. The second presenter, Keith Lamb, discusses the various benefits of PEEP, including improving oxygenation, reducing FiO2 requirements, improving compliance and work of breathing, and preventing atelectasis. He also highlights that PEEP can be used to mitigate auto-PEEP in patients with airflow obstruction. The third presenter, Cliff Grayson, focuses on the effects of PEEP on right ventricular (RV) function. He explains that PEEP can reduce venous return to the right atrium and right ventricle, which can be beneficial in some cases. However, excessive PEEP levels can increase RV afterload and potentially worsen right heart failure. Grayson also discusses the effects of PEEP on left atrial pressure and pulmonary vascular resistance and compliance. Overall, the video transcript provides an overview of the different aspects of optimizing PEEP in critical care and highlights the potential benefits and risks associated with PEEP strategies.
