Assessment of Effectiveness of Bain's Circuit Attached to a Niv Mask for Assisting Spontaneous Ventilation

ABSTRACT

Background: To assess effectiveness of Bain's circuit attached to a NIV mask for assisting spontaneous ventilation. Material(s) and Method(s) Fifty- six adult COVID- 19 patients were divided into 2 groups of twenty- eight each. In group I, patients were ventilated using the modified Bain's circuit attached to an appropriately sized NIV mask and in group II patients were continued on ventilation using BiPAP. Hemodynamic variables such as partial pressure of CO2 (pCO2), partial pressure of O2 (pO2), SO2, heart rate and pH values were recorded at baseline, after 30 minutes and after 2 hours. Result(s) There was non- significant difference in mean heart rate, SpO2, pH, pO2, pCO2 and SO2 at baseline, after 30 minutes after 2 hours in group I and group II (P> 0.05). Conclusion(s) Modified Bain's circuit can be considered as an alternative to non-invasive ventilation in COVID- 19 patients. Copyright © 2022 Necati Ozpinar. All Rights Reserved.
