This month’s Editor’s Choice is a survey of RT faculty and students to assess factors associated with the use of evidence-based practice (EBP). Clark and colleagues utilized an online questionnaire to determine knowledge of EBP, and self-efficacy related to knowledge and use of EBP. Faculty and students rated their self-efficacy high in assessing patients’ needs, values, and treatment preferences, but lower for use of the PICO technique and interpreting common statistical tests. They concluded that respiratory therapy faculty and students were knowledgeable and confident regarding EBP but their use of EBP in clinical decisions was limited. Varekojis provides accompanying commentary suggesting that introducing EBP concepts into RT curricula is foundational to provide EBP at the bedside. She strongly advises that RT faculty take responsibility to teach literature search strategies, critical appraisal of the literature, and basic concepts in statistical analysis.
Justice et al performed a bench study of ventilation using adult and pediatric manual resuscitators in a simulated adult patient. They recruited volunteers with prehospital emergency care experience. Volunteers used a bag valve mask (BVM) to ventilate a mannequin while measuring tidal volume (VT), breathing frequency, peak inspiratory pressure, and estimated alveolar ventilation. They found use of an adult BVM delivered an average VT of 290 mL, compared to 197 mL when using the …
