During both nasal noninvasive ventilation (NIV) and invasive ventilation of neonates, the presence of air leaks causes triggering and cycling asynchrony. ⋯ The ability of leak compensation to prevent asynchronous breathing varied widely between ventilators and lung mechanics. The PB980 and V500 were the only two ventilators to acclimate to all leak scenarios in invasive ventilation, and PB980 was the only ventilator to acclimate to all leak scenarios in NIV.

Review Meta Analysis Comparative Study
High-Flow Nasal Cannula in Critically Ill Subjects With or at Risk for Respiratory Failure: A Systematic Review and Meta-Analysis.
High-flow nasal cannula (HFNC) oxygen delivery has been gaining attention as an alternative means of respiratory support for critically ill patients, with recent studies suggesting equivalent outcomes when compared with other forms of oxygen therapy delivery. The main objective of this review was to extract current data about the efficacy of HFNC in critically ill subjects with or at risk for respiratory failure. We performed a systematic review of publications (from database inception to October 2015) that evaluated HFNC in critically ill subjects with or at risk for acute respiratory failure and performed a meta-analysis comparing HFNC with noninvasive ventilation (NIV) and with standard oxygen therapy regarding major outcomes: incidence of invasive mechanical ventilation and ICU mortality. ⋯ Additionally, HFNC use did not reduce ICU mortality compared with NIV (OR 0.72, 95% CI 0.23-2.21, P = .56) or with standard oxygen therapy (OR 0.69, 95% CI 0.33-1.42, P = .29). There was a trend toward better oxygenation compared with conventional oxygen therapy but a worse gas exchange compared with NIV. At this moment, HFNC therapy seems not to be superior to conventional oxygen therapy or NIV in terms of invasive mechanical ventilation rate or ICU mortality in critical illness, but new studies are needed to determine whether HFNC is associated with any difference in major outcomes when compared with other techniques.

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).

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.
