A 48-year-old man is brought to the emergency department via ambulance after coughing up approximately 600 mL of bright red blood over the past hour. He has a history of treated pulmonary tuberculosis. He is in moderate respiratory distress and continues to actively expectorate blood. His temperature is 37.1°C (98.8°F), blood pressure is 110/70 mm Hg, pulse is 118/min, and respirations are 28/min. Pulse oximetry shows an oxygen saturation of 87% on room air. A portable chest radiograph reveals a thin-walled cavity in the right upper lobe with an internal mass, alongside fresh patchy infiltrates in the right middle and lower lung zones. The left lung field is clear. Arrange the following acute management steps in the most appropriate chronological order.
- 1Place the patient in the right lateral decubitus position
- 2Perform endotracheal intubation
- 3Perform emergency bronchoscopy
- 4Consult interventional radiology for bronchial artery embolization
