Immediately titrate oxygen to target an SpO2 of 88-92% in COPD patients to correct hypoxia without blunting the hypoxic drive. Ensure nebulized bronchodilators are administered promptly to relieve bronchoconstriction.
Tachycardia, hypertension, and tachypnea are compensatory responses to hypoxemia. Treating the low SpO2 will resolve these secondary findings; do not treat them in isolation.
