Randomized Controlled Trial
Effects of 0 PEEP and < 1.0 FIO2 on SpO2 and PETCO2 During Open Endotracheal Suctioning.
Hyperoxygenation and hyperinflation, preferably with a mechanical ventilator, is the most commonly used technique to prevent the adverse effects of open endotracheal suctioning on arterial oxygenation and pulmonary volume. However, limited data are available on the effects of oxygen concentrations < 100% and PEEP with zero end-expiratory pressure (0 PEEP) to improve oxygenation and to maintain adequate ventilation during open endotracheal suctioning. The aim of this study was to analyze the behavior of [Formula: see text] and end-tidal CO2 pressure ([Formula: see text]) in open endotracheal suctioning using the 0 PEEP technique with baseline [Formula: see text] (0 PEEP baseline [Formula: see text]) and 0 PEEP + hyperoxygenation of 20% above the baseline value (0 PEEP [Formula: see text] + 0.20) in critically ill subjects receiving mechanical ventilation. ⋯ The appropriate indication of the hyperinflation strategy via mechanical ventilation using 0 PEEP with or without hyperoxygenation proved to be efficient to maintain [Formula: see text] and [Formula: see text] levels. These results suggest that the technique can minimize the loss of lung volume due to open endotracheal suctioning. (ClinicalTrials.gov registration NCT02440919).

Comparative Study
Comparison of the Oxygenation Factor and the Oxygenation Ratio in Subjects With ARDS.
The oxygenation ratio (ie, [Formula: see text]/[Formula: see text]) remains the most commonly used index for assessing oxygenation and disease severity in patients with acute ARDS. However, the oxygenation ratio does not account for mechanical ventilation settings. We hypothesized that the oxygenation factor (ie, oxygenation ratio/mean airway pressure) is superior to the oxygenation ratio in reflecting oxygenation in patients with ARDS and results in a different classification of ARDS severity. ⋯ The oxygenation factor was a superior ARDS oxygenation index compared to the oxygenation ratio and should be considered as a substitute criteria for classification of the severity of ARDS. (ClinicalTrials.gov registration NCT03946189.).

Respiratory failure after orthotopic liver transplantation is associated with increased mortality and prolonged hospitalization. ⋯ Early tracheostomy after transplantation was associated with lower in-hospital mortality, shorter post-tracheostomy length of stay, and quicker discharge alive. These results supported our hypothesis that, among subjects with respiratory failure after orthotopic liver transplantation, early tracheostomy after transplantation may be associated with more favorable outcomes than a delayed approach.

Advances in medicine and technology have led to improved survival rates of children with chronic respiratory disease such as cystic fibrosis, neuromuscular disease, and ventilator dependence. Survival into adulthood has created the need for adult specialists for conditions originating in childhood. Transition from pediatric to adult health care is a process that requires advanced planning and preparation and is not a one-time transfer event. ⋯ This narrative review summarizes the literature for health care transition from pediatric to adult care including the rationale, barriers, factors associated with successful transition, and special considerations. The intent of this review is to increase clinician awareness of health care transitions and the components necessary for an effective transfer of young adults with chronic respiratory disease. Understanding the transition process is an important consideration for both pediatric and adult clinicians, including respiratory therapists.
