Objective:

To discuss the evolution of mechanical ventilation towards personalized, physiology-guided approaches aimed at mitigating complications.

Approach:

• Personalization of Mechanical Ventilation: Merola et al. review evidence on how real-time monitoring of respiratory mechanics can prevent ventilator-induced lung injury (VILI).
• Impact of Inspiratory Rise Time: Tontu et al. study the effects of inspiratory rise time on mechanical power in patients with acute respiratory distress syndrome (ARDS).
• Lung-Protective Strategies in Surgery: Yue et al. and Wang et al. conduct trials showing that lung-protective ventilation reduces intraoperative complications in pediatric patients.
• Inspiratory Muscle Training: Andrade-Rebolledo et al. perform a meta-analysis indicating that inspiratory muscle training enhances respiratory muscle strength and weaning success.
• Risk Prediction for Extubation Failure: Zeng et al. review risk prediction models for extubation failure, emphasizing the need for integrating dynamic physiological variables.

Key Findings:

• Personalized mechanical ventilation can prevent ventilator-induced lung injury (VILI) and ventilator-induced diaphragmatic dysfunction (VIDD).
• Shortening inspiratory rise time significantly increases mechanical power in volume-controlled modes.
• Lung-protective strategies reduce intraoperative atelectasis in pediatric patients undergoing surgery.
• Inspiratory muscle training enhances respiratory muscle strength and improves weaning success rates.
• Risk prediction models for extubation failure require careful interpretation due to variability in patient characteristics.

Interpretation:

Mechanical ventilation is evolving towards a more individualized therapy that integrates respiratory physiology to improve patient outcomes.

Limitations:

• Statistical models for predicting extubation failure may not align with individual patient characteristics, limiting their applicability.
• Few studies have performed both internal and external validation of their risk prediction models.

Conclusion:

The articles collectively highlight the importance of personalized mechanical ventilation as a protective strategy in clinical practice.
