WebIn the treatment of an acute exacerbation of COPD, oxygen should be administered. The hypoxic drive theory has made many paramedics overcautious of administering oxygen. Although during oxygenation respiratory rates can reduce in some patients with COPD, within 15 minutes, the respiratory rate typically returns to sufficient levels.
