Effects of High-Flow Nasal Cannula Therapy Assessed by Electrical Impedance Tomography

Peking Union Medical College Hospital24 enrolled

Overview

This study aimed to determine the effects of HFNC therapy on lung recruitment and lung strain change assessed by electrical impedance tomography (EIT)

Study Type

OBSERVATIONAL

Enrollment

Conditions

High-flow Nasal Cannula Electrical Impedance Tomography

Interventions

High-flow nasal cannula (HFNC)OTHER

24 patients who receiving HFNC within 24 hours after extubation were prospectively enrolled in this study. EIT was used to monitor regional lung ventilation distributions at baseline (conventional oxygen therapy) and three flow rate levels of HFNC therapy (20, 40 and 60 L/min).

Eligibility
