The nurse must determine the patient's normal pulse oximetry values.The patient with end-stage COPD uses low oxygen levels to stimulate breathing rather than elevated carbon dioxide levels.When caring for patients with COPD and chronically elevated PaCO₂ levels,remember that inappropriate administration of excessive oxygen will result in hypoventilation.Patients with COPD and hypercapnia (high carbon dioxide levels)have adapted to the higher carbon dioxide level.Patients with respiratory difficulty should be assisted to sit up to facilitate lung expansion.STAT arterial blood gases are not needed.
