Description
ABSTRACT:
Background/Aim:
The aim of this study is to visualize the effect of a high flow nasal cannula (HFNC) in patients with the diagnosis of COVID-19 acute respiratory distress syndrome followed up in intensive care unit (ICU) with the use of electrical impedance tomography (EIT).
Materials and methods:
In two different flow rates, in supine and prone positions, and with the help of HFNC, oxygen therapy was applied. Patients’ EIT-based parameters (global inhomogeneity index (GI index), Center of Ventilation (CoV), Regional Ventilation Delay index (RVD index), Region of Interest Ratio (ROI ratio)), respiratory and hemodynamic parameters were recorded from the database.
Results:
Bu retrospektif gözlemsel çalışmaya yirmi hasta dahil edildi. Akış hızı kademeli olarak taban çizgisinden 50 L / dak'ya ve eğilimli konuma yükseldiğinde; GI endeksinin anlamlı ve tutarlı bir düşüş eğilimi: 0,55±0,02 (p < 0,0001), CoV: 42,98±0,93 (p <0,0001), RVD endeksi: 3,38±1,13 (p = 0,006), ROI oranı:1,39±0,16 (p <0,0001), respiartory oran: 21,3,3,57 (p ± 0,0001), ortalama arteriyel basınç: 81,5±<10,95 (p=0,004) ve azalan PaO 2/FiO2. oranı (kısmi arteriyel oksijen basıncı/esinlenmiş oksijen fraksiyonu): 203,1±33,44 ((p < 0.0001) gözlendi.
Conclusion:
It is found using EIT parameters that in patients with COVID-19 ARDS, prone position and increasing flow rate decreases lung heterogeneity.
