Noninvasive Positive Pressure Ventilation (NPPV) application to assist spontaneous breathing during FOB can be an alternative.Objective: Compare the application of NPPV (Philips-Respironics BiPAP Vision and Airox Supportair) vs Continuous Positive Airway Pressure (CPAP) valve (Boussignac) (CV) during FOB, in hypoxemic and/or hypercapnic patients, with various etiologies.Patients and methods: Fifteen (5 female) with severe hypoxemia defined by PaO2/FiO2&lt;200 and PaCO2&lt;60mmHg, submitted to FOB were eligible to the study. Seven patients were randomized to NPPV group (G1) and 8 to CV group (G2). At baseline 2 patients (G1) and 1 patient (G2) had PaCO2&gt; 45mmHg.Results [median (iqr)]: In G1 an IPAP of 23 (3)cmH2O, EPAP of 8 (2)cmH2O were applied and a FiO2 of 70 (50)% and in G2 a oxygen flow of 20 (8,6) L/min, generating a CPAP of 6 (4)cmH2O and a FiO2 of 60 (17,5)%. PaO2 improved after FOB in the whole group: 62,7 (16,1) vs 102,3 (97,1) mmHg post FBO, p=0,002, as well as PaO2/FiO2: 141,6 (57,2) and 203,9 (206) post FBO, p=0,002, and the PaCO2 remained within normal limits. Average SpO2 during FBO was not significantly different in both groups, 95,0 (5,9) in G1 vs 97,2 (0,9) in G2, (p=0,148). In G1 one patient was intubated.Conclusion: These results suggest that noninvasive positive pressure has an important role as adjunctive technique during FOB in severe hypoxemic patients (PaO2/FiO2&lt;200). In this preliminary study no advantage of NPPV vs CV. ER -
