Comparison of the Baska Mask Airway to a Single-use LMA Device in Low-risk Female Patients

The purpose of this study is to compare the performance of the Baska mask supraglottic airway device with a single use laryngeal mask device (LMA) in low-risk female patients. The investigators have performed a number of studies on novel airway devices, including 3 studies on the Baska mask. This trial will compare some performance characteristics of the studied devices, including airway seal pressures, insertion success rates, device use difficulty scores. Additional performance and device safety data will be accumulated. The investigators have two primary hypotheses, namely 1.Non-inferiority of first placement attempt success rate of the Baska mask vs LMA; and 2.greater seal pressure of the Baska mask vs LMA.
