Randomized Controlled Trial Comparative Study
Comparing the Effects of Two Different Levels of Hyperoxygenation on Gas Exchange During Open Endotracheal Suctioning: A Randomized Crossover Study.
Endotracheal suctioning is required for mechanically ventilated patients to maintain a patent airway. Studies show that open endotracheal suctioning affects respiratory mechanics and gas exchange. The aim of this study was to compare the effectiveness of hyperoxygenation with FIO2 + 0.20 above baseline and hyperoxygenation with FIO2 1.0 in preventing hypoxemia, and to determine the impact of open endotracheal suctioning on the pulmonary ventilation of critical subjects receiving mechanical ventilatory support. ⋯ In mechanically ventilated adult subjects, hyperoxygenation with FIO2 + 0.20 above baseline prevents hypoxemia. Also, transient changes in pulmonary ventilation with open circuit suctioning were confirmed by volumetric capnography analysis. (Trial registration: ClinicalTrials.gov NCT02440919).

ARDS is severe form of respiratory failure with significant impact on the morbidity and mortality of critical care patients. Epidemiological data are crucial for evaluating the efficacy of therapeutic interventions, designing studies, and optimizing resource distribution. The goal of this review is to present general aspects of mortality data published over the past decades. ⋯ The mortality trends over 3 time periods (before 1995, 1995-2000, and after 2000) yielded variable results in general ARDS populations. However, a mortality decrease was present mostly in prospective studies. Since 2010, the overall rates of in-hospital, ICU, and 28/30-d and 60-d mortality were 45, 38, 30, and 32%, respectively.

The population of children receiving long-term mechanical ventilation is growing worldwide, but only limited data exist in Asian regions. The objective of the study was to review the management of these children in Hong Kong over the past 2 decades. ⋯ Our study showed a steady growth in the number of children receiving long-term mechanical ventilation, similar to that in western countries, yet these children have distinct demographic characteristics, underlying diseases, comorbidities, and outcomes. Home care is feasible in the majority of these children despite a lack of in-home nursing care provision. Prolonged survival of these subjects necessitates the enhancement of transitional care to adult service.

Editorial Randomized Controlled Trial
A Respiratory Therapist Disease Management Program for Patients Hospitalized With COPD.
Patients with COPD often require repeated emergency department visits and hospitalizations for COPD exacerbations. Such readmissions increase health-care costs and expose COPD patients to the added risks of nosocomial infections and increased mortality. ⋯ Our RT disease management program was associated with less readmission, fewer ICU days, and shorter hospital stays due to COPD exacerbations. Further studies are needed to determine the optimal utilization of RT disease management teams for patients with COPD to optimize outcomes and prevent return hospital visits.
