Personalized Ventilation Based on Ventilation-perfusion Mismatch and Lung Recruitability

Personalized Ventilatory Strategy Based on Ventilation-perfusion Mismatch and Lung Recruitability in Moderate-to-severe ARDS Patients

Sponsor

Zhongda Hospital

Enrollment

40 participants

Start Date

Jun 8, 2024

Study Type

OBSERVATIONAL

Conditions

Mechanical Ventilation Respiratory distress syndrome Positive-Pressure Respiration

Summary

This observational study will explore the effects of PEEP and position on regional lung ventilation-perfusion mismatch by electrical impedance tomography (EIT) in moderate-to-severe ARDS patients with different lung recruitability.
