Uitkomstmaten
Primaire uitkomstmaten
Lung aeration of the 12 lung regions evaluated through Lung Ultrasound (LUS).
Achtergrond van het onderzoek
Monitoring of lung aeration is crucial in Intensive Care Unit (ICU) patients, especially in invasively ventilated patients. The gold standard for measuring lung aeration is chest Computed Tomography (CT). Unfortunately, a chest CT scan is difficult to obtain in invasively ventilated ICU patients and cannot be repeated frequently. Lung Ultrasound (LUS) as a point–of–care imaging tool is increasingly used in the (ICU) setting. Lung aeration by LUS is presently evaluated through semi–quantitative visual scores. Automated quantification could improve accuracy of lung aeration estimations. Our objective is to develop a computer–based algorithm for quantitative LUS analysis that accurately estimates lung aeration. A chest Computed Tomography (CT) scan will be used as the reference test.
Doel van het onderzoek
Artifacts on LUS images adequately reflect chest CT scan findings in invasively ventilated ICU patients; artifacts could be used in a computer–based quantitative algorithm for lung aeration.
Onderzoeksopzet
The Lung Ultrasound is performed close in time to the chest CT-scan.
