Bronchiolitis is the most common cause of admission in children < 2 y of age in the United States. The standard of care involves supportive measures, including noninvasive interventions such as CPAP. CPAP is traditionally delivered through a full face mask; however, pediatric ICUs have been exploring the use of the RAM cannula by Neotech as a mode of CPAP delivery. The level of CPAP delivered via the RAM cannula is uncertain. We performed an in vitro study to determine the level of CPAP delivered via the RAM cannula utilizing a pediatric lung model. ⋯ The RAM cannula delivered varying amounts of CPAP, with a percent loss of approximately -25% depending on the level of leak in the system. With minimal leak, it is conceivable that the RAM cannula can be used to deliver clinically meaningful CPAP.

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.

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.

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.
