Respiratory therapists (RTs) play important roles in providing ventilator support to patients in hospitals. They are on the front line in respiratory cases and work with physicians to help patients survive. However, questions remain regarding whether the mental health conditions at work are protected and secured for RTs. This study aimed to explore the risk factors of mental illness for RTs and to design an app to allow individual RTs to seek assistance at an earlier stage. ⋯ Four risk factors were verified to influence RT mental health. An app was developed to detect their mental health and allow them to seek assistance at an earlier stage.

Aerosol transport during noninvasive ventilation follows the flow of pressurized gas through the noninvasive ventilation circuit, vented via leak port and face mask, and inhaled by the patient. Recommendations for nebulizer placement are based on in vitro models that have focused primarily on aerosol losses via the leak port; face mask leaks have been avoided. This study tested aerosol delivery in the setting of controlled face mask leak. ⋯ During noninvasive ventilation, nebulizer placement at the ventilator outlet, which is a more practical position, is effective and minimizes deposition on face and mask. Aerosol therapy should be avoided when there is high face mask leak.

Review Meta Analysis
Neuromuscular Blocking Agents for ARDS: A Systematic Review and Meta-Analysis.
Studies evaluating neuromuscular blocking agents (NMBAs) in the management of ARDS have produced inconsistent results in terms of their effect on mortality. The purpose of this systematic review and meta-analysis was to evaluate differences in mortality comparing subjects with ARDS who received NMBA to those who received placebo or usual care. ⋯ In subjects with ARDS, early use of NMBAs improves oxygenation, reduces the incidence of ventilator-induced lung injury, and decreases 21-28-d mortality, but it does not improve 90-d mortality. NMBAs should be considered for select patients with moderate-to-severe ARDS for short durations.

Children requiring a tracheostomy to maintain airway patency or to facilitate long-term mechanical ventilatory support require comprehensive care and committed, trained, direct caregivers to manage their complex needs safely. These guidelines were developed from a comprehensive review of the literature to provide guidance for the selection of the type of tracheostomy tube (cuffed vs uncuffed), use of communication devices, implementation of daily care bundles, timing of first tracheostomy change, type of humidification used (active vs passive), timing of oral feedings, care coordination, and routine cleaning. Cuffed tracheostomy tubes should only be used for positive-pressure ventilation or to prevent aspiration. ⋯ Tracheostomy tubes may be safely changed at postoperative day 3, and they should be changed with some regularity (at a minimum of every 1-2 weeks) as well as on an as-needed basis, such as when an obstruction within the lumen occurs. Care coordination can reduce length of hospital and ICU stay. Published evidence is insufficient to support recommendations for a specific device to humidify the inspired gas, the use of a communication device, or timing for the initiation of feedings.

Although specific guidelines exist for diagnosing COPD on the basis of spirometry testing data (FEV1/FVC < 0.70 or above the lower limit of normal), the literature suggests that overdiagnosis is common. Whether overdiagnosis increases 30-d readmission rates has not yet been explored. The objective of this study was to determine the prevalence of COPD overdiagnosis and its effect on 30-d hospital readmission rates in our institution. ⋯ COPD was overdiagnosed in our cohort of subjects; this was true whether the FEV1/FVC < 0.70 standard or the lower limit of normal standard was used. Furthermore, this overdiagnosis artificially inflated the 30-d readmission rate. These results illustrate the caution providers should use when making a COPD diagnosis.
