Evaluation of Mechanical Power and Ventilator Parameters to Predict Weaning Success in the Intensive Care Unit

Inclusion Criteria: \- Age ≥ 18 years (adult patient population) * Patients receiving invasive mechanical ventilation in the intensive care unit * Having been intubated for at least 24 hours * Patients for whom the clinical team has decided extubation and who meet the following weaning criteria: * Stable respiratory parameters (FiO₂ ≤ 40%, PEEP ≤ 5 cmH₂O, SpO₂ ≥ 92%) * Hemodynamic stability (no inotropic support or minimal/stable dose) * Appropriate neurological status (able to follow commands) * Stable acid-base balance * Adequate secretion control * Technically suitable ventilator and measurement conditions * Written informed consent obtained from the patient or legal representative Exclusion Criteria: * Patients with any of the following conditions will be excluded: and * Individuals under 18 years of age * Pregnant patients * Patients who do not meet the weaning criteria * Tracheostomized patients * Neuromuscular diseases (e.g., Guillain-Barré syndrome, Duchenne muscular dystrophy, etc.) * Technical inadequacy preventing correct ventilator measurements * Significant asynchrony (e.g., auto-PEEP, double triggering, ineffective triggering, cycle asynchrony, auto-triggering) * Patients without an extubation plan or those receiving palliative care * RASS ≤ -2 (excessive sedation) for PSV mode measurements * RASS ≥ +2 (agitation) for PSV-CPAP mode measurements * Patients with delirium for PSV-CPAP mode measurements * Patients who cannot provide consent, have no legal rep…
