[Comparison of eight deep breaths and tidal volume breathing preoxygenation techniques in morbid obese patients].

Abstract

OBJECTIVE To compare two techniques of preoxygenation, eight deep breaths (8DB) and tidal volume breathing in obese patients by measuring end-tidal fractional oxygen concentration (FETO2) and apnea time from 100% of hemoglobin saturation to 95% (T95%). STUDY DESIGN Prospective randomized study. METHODS Twenty obese patients (BMI >40 kg/m2) without… (More)
