Effects of 50% Nitrous Oxide on Laryngeal Mask Airway Cuff Pressures at 5 MinuteIntervals for 30 Minutes

摘要

This study tested the effects of 50% nitrous oxide and 50% oxygen had onlaryngeal mask airway cuff pressures over 30 minutes. An experimental design was chosen and a sample of 30 trials were ran. The trials were ran in vitro. An intubation manikin was used to approximate clinical conditions. All cuff samples were checked by spectrometer after each trial to measure nitrous oxide absorption. This study revealed a dramatic increase in cuff pressures due to 50% nitrous oxide exposure over 30 minutes. Using a repeated measures ANOVA, a statistical significant finding (p% < .001) occurred.
