Abstract<\/h3>\n

Patient-ventilator asynchrony (PVA), a frequent mismatch between the patient\u2019s breathing effort and ventilator support, can lead to adverse outcomes such as prolonged ventilation, lung injury, and diaphragm dysfunction. While visual detection is difficult and time-consuming, artificial intelligence (AI) offers promise for real-time, accurate PVA identification. This review evaluates 19 studies using rule-based, machine learning (ML), and deep learning (DL) approaches, highlighting challenges and future pathways for clinical integration.<\/p>\n

Key Points:<\/h3>\n
    \n
  1. \n

    Prevalence and Consequences of PVA:<\/strong> PVA is highly prevalent (up to 90% of mechanically ventilated patients) and linked to worsened outcomes such as VILI, diaphragm atrophy, longer ventilation duration, and higher mortality.<\/p>\n<\/li>\n

  2. \n

    Limitations of Visual Inspection:<\/strong> Clinician-based waveform interpretation is inconsistent and labor-intensive, often underestimating both frequency and type of PVA due to the complexity and continuous nature of ventilator data.<\/p>\n<\/li>\n

  3. \n

    Types of AI Used:<\/strong> Reviewed approaches include rule-based systems (with fixed thresholds), ML algorithms (e.g., random forests), and DL neural networks, each with unique strengths and limitations in PVA detection accuracy and generalizability.<\/p>\n<\/li>\n

  4. \n

    Rule-Based Performance:<\/strong> Although transparent and clinically intuitive, rule-based algorithms detect limited PVA types and may lack robustness across patient populations.<\/p>\n<\/li>\n

  5. \n

    ML Algorithms Expand Capabilities:<\/strong> ML models have shown high sensitivity and specificity (e.g., >0.90 for premature and delayed cycling) and can detect multiple PVA types simultaneously, especially with adequate feature engineering.<\/p>\n<\/li>\n

  6. \n

    Advantages of Deep Learning:<\/strong> DL models, particularly recurrent and convolutional neural networks, outperform rule-based and ML systems in robustness and generalizability, especially for detecting ineffective efforts and double triggers.<\/p>\n<\/li>\n

  7. \n

    Licensed Software Examples:<\/strong> Commercial solutions such as Better Care\u00ae, Syncron-E\u2122, and Remote-VentilateView are emerging, but often detect only a subset of PVAs (mostly ineffective efforts) and require further clinical validation.<\/p>\n<\/li>\n

  8. \n

    Lack of Gold Standards:<\/strong> Most studies lack esophageal pressure (Pes) or diaphragm electrical activity (EAdi) data for validation, undermining their ability to truly gauge patient effort and creating a barrier to widespread acceptance.<\/p>\n<\/li>\n

  9. \n

    Real-Time and Bedside Integration Challenges:<\/strong> For clinical deployment, algorithms must shift from offline validation to real-time performance in diverse ICU environments with standardized inputs, outputs, and definitions of PVA.<\/p>\n<\/li>\n

  10. \n

    Future Directions:<\/strong> The authors emphasize the need for multicenter datasets, integration of ground truth markers like Pes\/EAdi, standardization of PVA types, and transparent AI models that can adapt across ventilator modes and patient phenotypes.<\/p>\n<\/li>\n<\/ol>\n

    Conclusion<\/h3>\n

    AI-based detection of patient-ventilator asynchrony is a promising tool to improve personalized mechanical ventilation by reducing clinician workload and improving detection accuracy. However, to achieve real-time bedside implementation, future efforts must focus on algorithm generalizability, comprehensive PVA detection across types, and external validation using gold-standard physiological markers like Pes and EAdi. Standardized frameworks and collaborative validation studies will be crucial to realize the full clinical impact of AI in managing PVA.<\/p>\n
