Launching the New Classic Papers Series in Our Journal Club on Respiratory Support and Related Topics – Featuring Professor Peter M. Suter's Landmark Study

👉 The article "Optimum End-Expiratory Airway Pressure in Patients with Acute Pulmonary Failure," published in the New England Journal of Medicine (Suter et al., 1975), was one of the first to systematically explore PEEP titration in critically ill patients, significantly shaping modern mechanical ventilation practices.

👉 The study aimed to evaluate the effects of PEEP in 15 normovolemic patients with acute pulmonary failure (ARDS) and determine the optimal level that balances oxygenation and hemodynamic stability.

🧐 The optimal PEEP is not just the one that improves oxygenation but the one that provides the best balance between alveolar recruitment and hemodynamic stability, ensuring adequate oxygen delivery to tissues and organs without compromising cardiac output.

🧐 The study made groundbreaking observations on the behavior of VD/VT and Cst in response to PEEP adjustments and how these parameters can help determine the optimal PEEP for each patient.

👉 The most striking finding of this seminal physiological study was the realization that if an increase in PEEP led to a decrease in Cst, a drop in cardiac output, or an excessive rise in VD/VT, the authors identified that PEEP had surpassed the optimal level.

👉 Furthermore, the combination of PEEP that results in the highest Cst and the lowest VD/VT corresponds to the value that optimizes oxygen delivery.
