The aim of CPAP and noninvasive ventilation (NIV) is to correct sleep-disordered breathing and nocturnal gas exchange. The aim of the study was to analyze the results of a systematic home pulse oximetry ([Formula: see text]) and transcutaneous carbon dioxide ([Formula: see text]) monitoring in stable pediatric subjects on long-term CPAP/NIV or screened for CPAP/NIV weaning, and the consequent interventions in the subjects with abnormal gas exchange. ⋯ A significant number (∼12%) of systematic home [Formula: see text] and [Formula: see text] recordings in stable pediatric subjects treated with CPAP/NIV were abnormal and may be corrected by adequate therapeutic interventions.

The transition from an ICU ventilator to a portable home ventilator (PHV) for children requiring long-term mechanical ventilation is a crucial step in preparing for discharge home and may not be successful on the first attempt. A review of this process at our institution revealed that some children required multiple trials before they were able to tolerate a PHV. A protocol was developed to standardize the transition process and reduce the number of failed attempts. Key features of the protocol included a transition readiness assessment and criteria for changing to the PHV. ⋯ The process of changing from an ICU ventilator to a PHV in children requiring long-term mechanical ventilation was improved through the use of a standardized protocol. Both the number of failed attempts and the length of time to achieve successful transition were reduced when the protocol was applied. Further study is needed to evaluate other medical and nonmedical factors that may affect successful transition to a PHV.

Pediatric ARDS is a heterogeneous disease entity with high morbidity and mortality. In this study, we categorized pediatric ARDS by direct and indirect initial triggering events and identified characteristics of survivors and nonsurvivors in these 2 subtypes. ⋯ Direct and indirect pediatric ARDS had distinct clinical characteristics, especially in terms of prognostic factors. Variables related to mechanical ventilation were significantly associated with mortality among subjects with direct pediatric ARDS, but not among subjects with indirect pediatric ARDS. Thus, this study provides evidence of the potential benefit of categorizing patients with pediatric ARDS by subtype for evaluating prognostic factors and developing adjusted management strategies to improve clinical outcomes.

Airway clearance techniques (ACTs), including high-frequency chest wall oscillation (vest therapy), are important for maintaining lung function for patients with cystic fibrosis, but daily completion of ACTs is time-consuming and cumbersome. Patient adherence is a persistent challenge, and adherence data are largely patient reported, which may reduce accuracy. To provide definitive adherence data, this study utilized a Bluetooth-enabled vest therapy system to remotely collect objective adherence data from a cohort of pediatric subjects. ⋯ Employing new technology to remotely collect vest usage data allows for a granular examination of vest therapy adherence. While maintaining high levels of treatment adherence becomes increasingly difficult as children age, we also found substantial reductions in adherence rates among all age groups when more complex aspects of therapy prescriptions, such as frequency and pressure settings, were examined. These data illustrate areas providers and care teams can focus on to improve patient adherence to vest prescriptions.

The patient who is morbidly obese is not adequately represented in the evidence recommending intraoperative low tidal volume (VT) ventilation. We aimed to explore the association between VT adjusted for ideal body weight (IBW) and the occurrence of postoperative pulmonary complications in subjects who were morbidly obese and undergoing abdominal surgery, as well as its implications on intraoperative ventilatory variables. ⋯ VT/IBW was not associated with the occurrence of postoperative pulmonary complications in subjects who were morbidly obese and undergoing prolonged abdominal surgery. Future prospective studies are indicated to guide the optimum ventilation strategy for patients who are morbidly obese.
