Relationship Between Chronic Lung Disease Diagnosis and Susceptibility to E-Cigarette Use in Adults.
Electronic cigarettes (e-cigarettes) are known to cause adverse pulmonary effects, yet paradoxically, the prevalence of e-cigarette use has increased among individuals with chronic lung disease. We assessed the relationship between chronic lung disease and the susceptibility to e-cigarette use in adults and determined if specific behavioral, social, and environmental factors influence this relationship. ⋯ Individuals without chronic lung disease were more susceptible to e-cigarette use than those with chronic lung disease. Although the prevalence of some behavioral and environmental factors differed among individuals with and without chronic lung disease, these factors did not moderate the association between chronic lung disease and susceptibility to e-cigarette use. Longitudinal investigations are warranted to better test the temporal relationships between chronic lung disease, substance use, social and environmental factors, and the susceptibility to e-cigarette use among individuals with chronic lung disease to identify prevention strategies for this population.

Our institution was experiencing a respiratory therapy staffing crisis during the COVID-19 pandemic, in part due to excessive workload. We identified an opportunity to reduce burden by limiting use of 3% hypertonic saline and/or N-acetylcysteine nebulizer therapies (3%HTS/NAC). ⋯ Implementing a policy that empowers respiratory therapists to promote adherence to AARC Clinical Guidelines reduced low-value therapies, costs, and staffing needs.

Adaptive ventilation mode (AVM) is a automated mode of mechanical ventilation. AVM is comprable to adaptive support ventilation (ASV). Both recommend a tidal volume (VT) and breathing frequency (f) combination based on lung mechanics, but AVM also automatically adjusts rise time and flow termination of pressure support breaths. How these added features of AVM affect VT and f recommendations compared to ASV is not clear. The present study compared these 2 modes in a test lung with obstructive and restrictive mechanics. ⋯ The addition of automatic control of rise time and flow termination functions did not affect recommended ventilator settings in AVM in the noncompliant or obstructive lung when minute ventilation (V̇E) was low. At higher V̇E, AVM compared to ASV recommended a ventilatory strategy with lower VT and higher f. These results need to be validated in patients.
