The Effectiveness Study of OLE Airway Clearance Therapy in ICU Patients With Pulmonary Infections in EIT Evaluation.
This study aims to explore the application of Electrical Impedance Tomography (EIT) in evaluating the effectiveness of OLE (Oscillatory Lung Expansion) airway clearance therapy for ICU patients with pulmonary infections. The goal is to understand the treatment response differences in patients with various causes of atelectasis (lung collapse). The study will include adult patients diagnosed with pulmonary infections and admitted to the ICU. The primary endpoint of the study is the peak cough flow (CPF), which measures the patient's ability to clear secretions from the lungs through coughing.
• Clearly diagnosed with pulmonary infection in the ICU, confirmed by microbiological tests (sputum culture, blood culture, etc.) or imaging tests (chest CT, chest X-ray);
• Age ≥ 18 years;
• Respiratory support is oxygen therapy (nasal cannula or face mask oxygen therapy);
• Sputum volume \> 30 ml/day;
• The patient or their legal representative signs the informed consent form.
