Multicenter Study
Ventilation Management and Outcomes for Subjects With Neuromuscular Disorders Admitted to ICUs With Acute Respiratory Failure.
Patients with neuromuscular disorders (NMD) share the risk of acute respiratory failure (ARF) leading to ICU admissions. Noninvasive ventilation (NIV) is often proposed as an alternative to invasive ventilation. This study describes clinical features, ventilation management, and outcomes of subjects with NMD admitted to ICU and managed for ARF. ⋯ The ICU mortality of NMD subjects with ARF was low, with no impact of bulbar muscles involvement. NIV was proposed for approximately half of the subjects, and it was more effective when ARF was not attributed to bulbar musculature involvement. The long-term outcome was good.

Review Case Reports
Telerehabilitation in Subjects With Respiratory Disease: A Scoping Review.
Considering the current coronavirus disease (COVID-19) pandemic, telerehabilitation may be a viable first-line option for patients with respiratory tract disease. To date, there has been no systematic review on telerehabilitation for respiratory tract diseases, including COVID-19. Therefore, this scoping review aimed to determine what telerehabilitation for patients with respiratory tract diseases consists of, how safe telerehabilitation is for patients with respiratory tract diseases, and how feasible telerehabilitation is for hospitalized patients with COVID-19. ⋯ The majority of the telerehabilitation programs included a face-to-face rehabilitation assessment. Our findings indicate that, in its current state, telerehabilitation may be safe and feasible and may lead to reduced face-to-face rehabilitation therapy; in addition, remote rehabilitation assessment should be considered during the COVID-19 pandemic. Further research that targets a more diverse range of respiratory tract diseases and considers telerehabilitation in a hospital setting is required.

We hypothesized that the lack of benefit of setting a low versus a high PEEP in patients with ARDS may be due in part to differences in the dynamic behavior of the expiratory valve in ventilators. We tested this hypothesis by conducting a bench comparison of the dynamic behavior of expiratory valves on ICU ventilators currently in use. ⋯ The resistance of active expiratory valves differed significantly between the 7 ICU ventilators tested.

Protocol-driven therapy has been successful in managing patients with asthma on pediatric wards, but there is wide variability in ICU-level management that is often provider-dependent. This study aimed to determine if a standardized protocol for critical asthma treatment could improve clinical outcomes. ⋯ Implementation of an asthma protocol in the pediatric ICU did not result in significant improvements in time on continuous albuterol or hospital and pediatric ICU LOS, likely due to low adherence to the protocol. However, in subjects who did adhere to the protocol there were significant reductions in the outcome measures.

Diaphragmatic respiratory effort during mechanical ventilation is an important determinant of patient outcome, but direct measurement of diaphragmatic contractility requires specialized instrumentation and technical expertise. We sought to determine whether routinely collected clinical variables can predict diaphragmatic contractility and stratify the risk of diaphragm atrophy. ⋯ Diaphragmatic contractility and the risk of diaphragm atrophy could not be reliably determined from routinely collected clinical variables and ventilator settings. A single measurement of diaphragm thickening fraction measured within 48 h of initiating mechanical ventilation can be used to stratify the risk of diaphragm atrophy during mechanical ventilation.
