Moreover, in a patient with EtCO2 of 53mmHg, the bronchoscopy, limited to a fast airway inspection with aspiration, did not give complications, even with a moderate CO2 increase.ConclusionsB-CPAP system, during bronchoscopic maneuvers, for oximetry, EtCO2, for the reduction of dyspnea, formed, in our experience, an alternative procedure to the endotracheal intubation and mechanical ventilation, expecially in COPD patients with tendency toward hypercapnia.
