Advances in achieving lung and diaphragm-protective ventilation.

Area of Science:

• Critical Care Medicine
• Respiratory Physiology
• Mechanical Ventilation

Background:

• Mechanical ventilation can negatively impact diaphragm and lung function.
• Lung- and diaphragm-protective ventilation aims to balance physiological respiratory efforts with minimal lung stress.
• This review focuses on recent advancements in achieving these protective ventilation strategies.

Purpose of the Study:

• To discuss the latest monitoring techniques and interventions for lung- and diaphragm-protective ventilation.
• To highlight the importance of a comprehensive approach to mechanical ventilation.
• To provide a bedside strategy for implementing protective ventilation.

Main Methods:

• Review of noninvasive ventilator maneuvers (e.g., P0.1, occlusion pressure).
• Inclusion of advanced monitoring: esophageal manometry, ultrasound, diaphragmatic electrical activity, electrical impedance tomography.
• Analysis of recent clinical trials on titrating ventilatory support and sedation.

Main Results:

• Noninvasive maneuvers accurately detect respiratory effort and lung stress.
• Multiple monitoring techniques aid in assessing lung and diaphragm function.
• Systematic titration of inspiratory support, sedation, and PEEP facilitates protective ventilation.
• Extracorporeal membrane oxygenation (ECMO) sweep gas flow can modulate neural respiratory drive.

Conclusions:

• Achieving lung- and diaphragm-protective ventilation requires a multifaceted approach.
• Understanding breathing physiology and mechanical ventilation is crucial.
• A systematic bedside approach integrating monitoring and interventions is recommended.
