Here is Fraser’s very helpful talk on the management of patients with acute exacerbations of COPD, specifically indications for NIV. This talk included a discussion on the utility of VBG vs ABG vs CBG in the emergency setting. The current indication suggested by Fraser / ?SCGH Respiratory Medicine Dept is shown in the algorithm below. I have included links to some of the relevant current research and reviews on this topic below.
