학습 자료 둘러보기 →In a patient with COPD exacerbation, a new onset of restlessness or confusion accompanied by an increased respiratory rate is a critical early warning sign. This reflects the brain's high sensitivity to hypoxemia and hypercapnia, indicating that compensatory mechanisms are failing.
Prioritize immediate assessment of oxygen saturation and arterial blood gases. Do not attribute these changes solely to anxiety or fatigue. A confused patient is at high risk for impaired self-management and rapid clinical deterioration.
Any acute alteration in mental status in a COPD patient is a medical emergency. Delaying escalation of respiratory support while awaiting lab results can lead to respiratory arrest. Monitor closely for a rising PaCO2 level.
