Assessing the use of initial oxygen therapy in chronic obstructive pulmonary disease patients: a retrospective audit of pre-hospital and hospital emergency management

摘要

BackgroundCarbon dioxide retention in chronic obstructive pulmonary disease (COPD) exacerbations can be a complication of oxygen therapy. Current recommendations suggest an inspired oxygen level (FiO(2)) < 0.28, aiming for saturation (SpO(2)) of 88-92% until arterial blood gas analysis is available.
