Summary

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.

Conditions

• Pneumonia

Interventions

Type	Name	Description
DEVICE	Oscillatory Lung Expansion (OLE) Therapy	The OLE treatment device is used with synchronized nebulization of 10 ml of 0.9% NaCl solution. The continuous positive airway pressure during the exhalation phase is set to 10-20 cmH₂O, with continuous high-frequency oscillation at a rate of 170-230 times per minute. Each treatment session lasts for 10 minutes. The oxygen therapy parameters are set by the clinician and remain unchanged throughout the experiment.
