Surveys provide evidence for the social sciences for knowledge, attitudes, and other behaviors, and, in health care, to quantify qualitative research and to assist in policymaking. A survey-designed research project is about asking questions of individuals, and, from the answers, the researcher can generalize the findings from a sample of respondents to a population. Therefore, this overview can serve as a guide to conducting survey research that can provide answers for practitioners, educators, and leaders, but only if the right questions and methods are used. ⋯ Online surveys have many limitations that should be expected before conducting a search, and then described after the survey is complete. Any conclusions and recommendations are to be supported by evidence in a clear and objective manner. Presenting evidence in a structured format is crucial but well-developed reporting guidelines are needed for researchers who conduct survey research.

Aerosolized drug delivery via high-flow nasal cannula (HFNC) decreases as gas flow is increased. To improve aerosol delivery, breath-enhanced jet nebulizer may increase aerosol output. This study tested that hypothesis and compared breath-enhanced jet nebulizer to vibrating mesh nebulizer technology. ⋯ Increasing gas flow increased breath-enhanced jet nebulizer output, which demonstrated the effects of breath enhancement. At 60 L/min, breath enhanced jet nebulizer delivered up to 5 times more aerosol compared with conventional vibrating mesh nebulizer technology. Breath-enhanced jet nebulizer delivered a wide range of dose rates at all high flows. In patients who are critically ill, breath-enhanced jet nebulizer technology may allow titration of bedside dosing based on clinical response by simple adjustment of the infusion rate.
