Physiology-guided mechanical ventilation: Monitoring, proportional assist, and bounded automation

Abstract: Mechanical ventilation has evolved into a complex intervention that influences lung injuries, respiratory muscle function, and hemodynamic stability. Although lung-protective strategies improve outcomes in acute respiratory distress syndrome, bedside management remains limited by incomplete monitoring of key physiologic variables, including lung stress, inspiratory effort and regional ventilation. This constrains decision such as positive end-expiratory pressure titration and ventilatory assist targeting. Emergi…

The quick read

Published September 9, 2026, this peer-reviewed review outlines a pragmatic framework for physiology-guided mechanical ventilation that combines advanced monitoring, proportional assist modes, and bounded automation. It notes that automation and artificial intelligence are increasingly used for waveform analysis, asynchrony detection, and weaning prediction within predefined safety limits.

The integration matters because incomplete bedside assessment of lung stress, inspiratory effort, and regional ventilation currently limits PEEP titration and assist targeting, affecting lung injury and hemodynamic stability. Uncertainty remains about whether improved synchrony and AI-supported decision-making translate consistently into better patient-centered outcomes.

Main points
  • Mechanical ventilation influences lung injury, respiratory muscle function, and hemodynamic stability, with lung-protective strategies improving ARDS outcomes.
  • Emerging physiologic tools include esophageal manometry, airway occlusion pressure (P0.1), diaphragm electrical activity, and electrical impedance tomography for lung mechanics and regional ventilation.
  • Proposed framework integrates physiologic monitoring, proportional assist, and bounded decision support to optimize lung protection, diaphragm function, and hemodynamic stability.
Gain

Automation and AI applied to ventilator management support waveform analysis, asynchrony detection, and weaning-readiness prediction to enable more individualized lung-protective care within predefined safety limits.

The rundown

The source describes evolution of mechanical ventilation beyond basic support to an intervention affecting lung injury, muscle function, and hemodynamics, noting that lung-protective strategies help in ARDS but bedside decisions are constrained by gaps in monitoring lung stress, effort, and regional ventilation.

It details emerging assessment tools such as esophageal manometry, P0.1, diaphragm electrical activity, and electrical impedance tomography, and discusses proportional assist modes that improve synchrony while noting variable patient-centered results, proposing integration with bounded AI decision support.
