Efficacy of preoxygenation using tidal volume breathing: a comparison of Mapleson A, Bain's and Circle system

Rev. bras. anestesiol; 68 (2), 2018
Abstract Background: Efficacy of preoxygenation depends upon inspired oxygen concentration, its flow rate, breathing system configuration and patient characteristics. We hypothesized that in actual clinical scenario, where breathing circuit is not primed with 100% oxygen, patients may need more time to ...
