A 56-year-old barrel-chested male is in a tripod position and speaks in 2-3 word sentences. He has a lengthy smoking history. What should you do first?

Noninvasive positive-pressure ventilation is the best first move for a patient with an acute COPD exacerbation presenting in significant respiratory distress. The barrel chest, tripod stance, long smoking history, and the ability to speak only in short phrases all point to fatigue from airway obstruction but with an airway that remains protectable. Applying CPAP provides continuous positive pressure that helps keep airways open, recruits collapsed alveoli, increases functional residual capacity, and reduces the work of breathing. This improves oxygenation and ventilation without the risks of intubation. Starting with high-flow oxygen alone can help but may not address the underlying ventilation issues in COPD and, if FiO2 is excessive, can worsen CO2 retention in some patients. Intubation is reserved for failure of noninvasive support or if the patient cannot protect the airway or deteriorates. Placing the patient supine would worsen breathing mechanics. So, CPAP is the appropriate initial intervention.
