Contemplating the future should be grounded in history. The rise of post-polio ICUs was inextricably related to mechanical ventilation. Critically ill patients who developed acute respiratory failure often had "congestive atelectasis" (ie, a term used to describe ARDS prior to 1967). ⋯ Therefore, it is imperative we understand the long-crooked path needed to reach the era of protective ventilation in order to avoid similar mistakes moving forward. The emerging era is as difficult to fathom as our current practices and technologies were to those practicing 60 years ago. This review explores the history of mechanical ventilation in treating ARDS, describes current protective ventilation strategies, and speculates how ARDS management might look 20 years from now.

Multicenter Study
Flexible Bronchoscopy in Pediatric Venovenous Extracorporeal Membrane Oxygenation.
Pediatric patients with ARDS will on occasion need venovenous extracorporeal membrane oxygenation (VV-ECMO) for organ support. As these patients recover, they may benefit from lung recruitment maneuvers including flexible bronchoscopy (FB). The objective of this study was to assess the clinical course of patients who underwent FB while on VV-ECMO for ARDS. ⋯ FB can be performed on patients while anticoagulated on VV-ECMO with a low incidence of complications. FB may be beneficial especially when performed early in the course of VV-ECMO.

In 2015, the Centers for Medicare and Medicaid Services limited payments to hospitals with high readmission rates for patients admitted with COPD exacerbation. Decreasing readmissions in this patient population improves patient health and decreases health care utilization of resources. We hypothesized a COPD disease management program delivered by a respiratory therapist (RT) in the patient's home may reduce readmission rates for COPD exacerbation. ⋯ The COPD Disease Management Program is significantly associated with decreased readmission adjusting for demographics and smoking status.

Teaching and learning using simulation-based methods is increasing in health professions education; however, the prevalence of simulation use in respiratory care programs to date has not been explored. ⋯ Simulation-based teaching and learning is widespread and varied, but there is a lack of faculty development in its use among respiratory care programs.

There are several tests recommended by the American Thoracic Society (ATS) to evaluate for airway hyper-responsiveness (AHR), one of which is methacholine challenge testing (MCT). Few studies have examined the correlation of baseline spirometry to predict AHR in MCT, especially in the younger, relatively healthy military population under clinical evaluation for symptoms of exertional dyspnea. The study aim was to retrospectively correlate baseline spirometry values with MCT responsiveness. ⋯ The analysis of baseline spirometry prior to MCT proved useful in the evaluation of exertional dyspnea in a military population. The presence of airways obstruction (FEV1/FVC < lower limit of the normal range) followed by a reduction in FEV25-75% < 70% predicted showed a positive correlation with underlying AHR. In patients with exertional dyspnea and normal baseline spirometry, the use of the FEF25-75% may be a useful surrogate measurement to predict reactivity during MCT and consideration for additional testing or treatment.
