Just leave it that way

Detailed explanation-1: -During an exacerbation of COPD, give 24% or 28% oxygen via a Venturi facemask to patients with hypercapnia in order to maintain an oxygen saturation > 90%. In patients without hypercapnia, titrate the oxygen concentration upwards to keep the saturation > 90%.
Detailed explanation-2: -For most patients with COPD, target saturation range should be set at 88–92% until blood gases are available. For all critically ill patients, high concentration oxygen should be administered immediately until the patient is stable.
Detailed explanation-3: -Uncompensated elevated Paco2 causes respiratory acidosis, and acidemia can be deadly. It may seem intuitively right to put a “blue” patient on a high concentration of inspired oxygen (Fio2). However, high Fio2 has been shown to be dangerous for patients with COPD, and guidelines advise against its use.
Detailed explanation-4: -For most COPD patients, you should be aiming for an SaO2 of 88-92%, (compared with 94-98% for most acutely ill patients NOT at risk of hypercapnic respiratory failure). Mark the target saturation clearly on the drug chart.
