Περίληψη: Patient–ventilator asynchrony is highly prevalent during invasive mechanical ventilation, yet its detection at the bedside remains limited. Conventional waveform inspection is intermittent, operator-dependent, and insufficient to capture the complexity and temporal variability of patient–ventilator interaction. Automated systems based on advanced signal processing and artificial intelligence represent a paradigm shift, enabling continuous, objective, and scalable detection of asynchrony. Recent approaches highlight the value of entropy-based metrics to quantify the irregularity of ventilatory signals and capture subtle changes in respiratory variability. Similarly, the identification of asynchrony clusters, periods where multiple asynchronous events occur in succession, provides a clinically relevant framework to stratify severity and predict outcomes. These developments underscore the superiority of automated methods over human observation alone. From an implementation perspective, centralized monitoring architectures offer greater potential than stand-alone devices, as they allow multimodal integration, data aggregation, algorithm refinement, and interoperability across platforms. Looking forward, research must expand toward the fusion of ventilatory, hemodynamic, and neurological signals to provide a comprehensive picture of patient–ventilator interaction. Particular attention should be paid to the long-term consequences of poor synchrony, as evidence suggests that asynchronies may influence functional recovery and health-related quality of life well beyond intensive care unit discharge. Robust, standardized datasets will ultimately support the generation of synthetic data and patient-specific digital twins, paving the way for precision-guided, adaptive mechanical ventilation.
