Respiratory care

Scientific research traditionally has been the domain of graduate school training, and it is based on higher cognitive levels associated with reflective thought. Such skills differ markedly from those needed to train competent respiratory therapists at the undergraduate level. Trainees at the undergraduate level need to acquire, comprehend, and apply large amounts of functional knowledge within a relatively brief time period. ⋯ Organizing and implementing a research program within a respiratory care department or training program require forethought and devoted leadership. Crucial to this endeavor is developing mentors to guide those with little or no exposure to scientific inquiry. This article provides an overview of the pedagogical issues that underlie this predicament and then describes practical steps that can be taken to slowly build such a program.

FEV1 as a Standalone Spirometric Predictor and the Attributable Fraction for Death in Older Persons.
Commonly used thresholds for staging FEV1 have not been evaluated as standalone spirometric predictors of death in older persons. Specifically, the proportion of deaths attributed to a reduced FEV1, when staged by commonly used thresholds in L, percent of predicted (% pred), and Z scores, has not been previously reported. ⋯ In older persons, the proportion of deaths attributed to a reduced FEV1 is best stratified by Z score staging thresholds because these yield a similar relative risk of death but a more age- and sex-appropriate prevalence of FEV1 stage.

The incidence of community-acquired pneumonia (CAP) is relatively high in elderly subjects. Cough peak flow (CPF) is an objective indicator of cough strength, and CPF evaluation might be useful to assess whether food intake can be restarted. We aimed to examine whether cough strength assessed with CPF can be used as an indicator of the aspiration risk when restarting food intake in elderly subjects with CAP. ⋯ Our findings suggest that cough strength assessed with CPF can be used as an indicator of the aspiration risk when restarting food intake in elderly subjects with CAP and that CPF evaluation is not inferior to the RSST. However, CPF evaluation should be performed together with swallowing screening tests to determine the aspiration risk.
