A recently introduced open oxygen mask design was marketed in 2021 (open mask A). The manufacturer claims that the mask "…provides one solution for all your oxygen delivery needs across your patients' continuum of care." The new oxygen mask specifies flow (1-15 L/min and flush) with an expected FIO2 from 0.25-0.85. This suggests that this mask eliminates the need for multiple oxygen delivery devices as FIO2 requirements change. This study aimed to describe the FIO2 performance of the new open oxygen mask and other commonly used oxygen masks. ⋯ The performance of each oxygen mask from highest to lowest FIO2 : non-rebreather, partial rebreather, simple mask, open mask A, and open mask B. These findings suggest that no oxygen mask tested serves as a substitute for the others across a flow range of 1-15 L/min and flush.

Although prior studies have established the association of asthma with smoking and obesity, literature on difference-in-differences analyses involving sexual identity is sparse. Therefore, this study aimed to examine the between and within sexual identity-group differences in asthma prevalence among individuals who smoke and are obese. ⋯ Smoking and obesity show heightened odds for asthma, with significant odds for sexual minorities in asthma diagnosis relative to heterosexuals. These findings provide formative information for future longitudinal and experimental studies to explore these mechanisms of asthma risks among sexual and gender minorities.
