The coronavirus disease 2019 (COVID-19) pandemic has produced numerous safety concerns for sleep medicine patients and health-care workers, especially related to the use of aerosol-generating positive airway pressure devices. Differences between physician and sleep technologist concerns with regard to viral exposure and mitigation strategies may inform protocols to ensure safety and promote patient and health-care worker resilience and retention. ⋯ Sleep health-care workers reported high levels of concern about exposure to COVID-19. Physicians and technologists generally showed high concordance with regard to the need for mitigation strategies, but the respondents differed widely with regard to which strategies were necessary.

Asthma is a prevalent disease that disproportionately affects socioeconomically underprivileged minorities. In fact, racial and ethnic minorities such as Blacks and Latinos have higher rates of severe asthma, asthma-associated emergency department visits, hospitalizations, and readmissions compared with whites. Such disparities exist due to genetic predispositions and to socioeconomic determinants of health such as environmental factors and limited health-care access. ⋯ Efforts have been made to address asthma-related complications in these populations, which have been addressed at various levels of the care system, including the patient and family, community, organization, provider/microsystem, and policy. Many of these programs promote patient education and health-care accessibility through interdisciplinary and multi-dimensional approaches, and have been shown to be effective in reducing asthma-associated readmissions and hospitalizations, but these localized approaches have not been largely adopted. The wide-spread implementation of asthma programs is necessary to address factors related to the increased incidence of asthma and associated rates of hospitalizations and readmissions in impoverished, minority populations.

High-flow nasal cannula (HFNC) is increasingly used for the management of respiratory failure. Settings include [Formula: see text], total gas flow, and temperature target. Resulting absolute humidity (AH) at the nasal cannula may affect clinical tolerance, and optimal settings with respect to hygrometry remain poorly documented. ⋯ When used according to manufacturer's recommendations and at normal ambient temperature, all the HFNC devices evaluated achieved satisfactory hygrometric output with respect to breathing comfort evaluated in healthy subjects (≥ 30 mg H2O/L). Substantial differences exist between devices, and optimal knowledge of their working principles is required as inappropriate usage may dramatically alter efficacy and clinical tolerance.
