SESSION TITLE: Mechanical Ventilation & Respiratory Failure II

SESSION TYPE: Original Investigation Poster

PRESENTED ON: Wednesday, October 26, 2016 at 01:30 PM - 02:30 PM

PURPOSE: Arterial blood gas (ABG) analysis is part of the assessment during COPD exacerbation, and arterial pH has been shown to predict non-invasive ventilation (NIV) failure, a risk factor for mortality. Venous blood gas (VBG) has gained popularity in Emergency Departments (ED) as a substitute for ABG, as studies have shown a good agreement between venous and arterial values for pH or PCO2. We aimed to investigate whether initial VBG can predict requirement for intubation during acute on chronic respiratory failure.
