Patients undergoing mechanical ventilation in the ICU often receive supplemental oxygen. If not closely monitored, this may lead to hyperoxia. The use of an oxygen-weaning protocol may reduce this risk by pacing the titration of oxygen therapy to patient needs. ICU protocols are correlated with decreased mortality and length of stay and have great potential for cost savings. The goals of this study were to determine whether the oxygen-weaning protocol at a university-affiliated hospital was followed and to measure the length of time respiratory therapists took to wean patients once the oxygen-weaning parameters were met. ⋯ Subjects admitted to the medical ICU who were intubated, mechanically ventilated, and placed on the oxygen therapy protocol experienced a significant delay in oxygen weaning. Closer monitoring and adherence to the oxygen-weaning protocol should be considered to reduce the potential risk for hyperoxia.

Despite the accepted importance of minimizing time on mechanical ventilation, only limited guidance on weaning and extubation is available from the pediatric literature. A significant proportion of patients being evaluated for weaning are actually ready for extubation, suggesting that weaning is often not considered early enough in the course of ventilation. Indications for extubation are often not clear, although a trial of spontaneous breathing on CPAP without pressure support seems an appropriate prerequisite in many cases. ⋯ New techniques for assessing readiness for weaning and predicting extubation success are being developed but are far from general acceptance in pediatric practice. While there have been some excellent physiologic, observational, and even randomized controlled trials on aspects of pediatric ventilator liberation, robust research data are lacking. Given the lack of data in many areas, a determined approach that combines systematic review with consensus opinion of international experts could generate high-quality recommendations and terminology definitions to guide clinical practice and highlight important areas for future research in weaning, extubation readiness, and liberation from mechanical ventilation following pediatric respiratory failure.

COPD and bronchiectasis frequently coexist, which creates an emerging phenotype with a worse prognosis. However, the impact of bronchiectasis on the natural history of COPD has not been fully evaluated and is still controversial. This meta-analysis was performed to clarify the associations of the presence of bronchiectasis with the prognosis and quality of life of patients with COPD. ⋯ This meta-analysis confirmed the significant associations of the presence of bronchiectasis with the natural history, disease course, and outcomes in COPD. The COPD-bronchiectasis phenotype had adverse effects on subjects' health condition and prognosis.

Multicenter Study
Respiratory Therapist Intubation Practice in Pediatric ICUs: A Multicenter Registry Study.
Tracheal intubation by respiratory therapists (RTs) is a well-established practice that has been described primarily in adult and neonatal patients. However, minimal data exist regarding RTs' intubation performance in pediatric ICUs. The purpose of this study was to describe the current landscape of intubations performed by RTs in pediatric ICUs. ⋯ RTs infrequently intubate in pediatric ICUs, with success rates similar to other providers but higher adverse event rates. RTs were more likely to use video laryngoscopy than other providers. RTs' intubation participation, success, and adverse event rates varied greatly across pediatric ICUs.
