Continuous Positive Airway Pressure during Fiberoptic Bronchoscopy in Hypoxemic Patients

Pdf Summary

The study conducted by Maitre et al. aimed to compare the effectiveness of continuous positive airway pressure (CPAP) versus oxygen supplementation in maintaining oxygenation during fiberoptic bronchoscopy (FOB) in hypoxemic patients. Thirty consecutive patients with arterial oxygen pressure (PaO2) to inspired oxygen fraction (FiO2) ratio below 300 mm Hg were enrolled in the study. CPAP was delivered through a new device open to the atmosphere, while the control group received oxygen only. Pulse oximetry values were significantly higher in the CPAP group during and after FOB, and the lowest oxygen saturation values were observed in the oxygen-only group. Arterial blood gases showed that PaO2 increased in the CPAP group and decreased in the oxygen-only group. Five patients in the oxygen-only group developed respiratory failure within 6 hours after FOB, while none in the CPAP group required ventilatory assistance. The authors concluded that the use of CPAP during FOB in hypoxemic patients allowed minimal alterations in gas exchange and prevented subsequent respiratory failure. The study suggests that CPAP can be a useful tool in maintaining oxygenation and promoting patient safety during FOB procedures.
