NIV CPAP during Bronch AJRCCM 2000 - PDF

Pdf Summary

Researchers conducted a study to compare the delivery of continuous positive airway pressure (CPAP) as a tool for maintaining oxygenation during fiberoptic bronchoscopy (FOB) to the delivery of oxygen only. Thirty patients with arterial oxygen pressure to inspired oxygen fraction (PaO2/FIO2) below 300 mm Hg were enrolled. The pulse oximetry values (SpO2) were significantly higher in the CPAP group during FOB and for 30 minutes afterward, compared to the oxygen group. The lowest SpO2 values were observed in the oxygen group. Arterial blood gases 15 minutes after FOB showed that PaO2 had increased in the CPAP group and decreased in the oxygen group. Five patients in the oxygen group developed respiratory failure in the six hours after FOB and required ventilatory assistance. The researchers concluded that the use of CPAP during FOB in hypoxemic patients allowed minimal alterations in gas exchange and prevented subsequent respiratory failure.
