Oxygen therapy is one of the most important therapeutics offered in the clinical management of pediatric patients with cardiopulmonary disease. As the medical community seeks to ensure evidence-based management of clinical interventions, we conducted a systematic review with the goal of providing evidence-based clinical practice guidelines to answer questions surrounding the use of simple oxygen therapy to improve oxygenation, including a comparison of delivery devices, the efficacy of humidification, comparison of flows, and goals for use in children. Using a modification of the RAND/UCLA Appropriateness Method, we developed 4 recommendations to assist clinicians in the utilization of oxygen therapy in hospitalized children: (1) the use of an oxygen hood or tent in lieu of a low-flow oxygen device for consistent oxygen delivery is not recommended; (2) the use of high-flow nasal cannula therapy is safe and more effective than low-flow oxygen to treat infants with moderate to severe bronchiolitis; (3) the application of humidification with low-flow oxygen delivery is not recommended; (4) targeting [Formula: see text] 90-97% for infants and children with bronchiolitis is recommended; however, no specific target can be recommended for pediatric patients with respiratory diseases outside of bronchiolitis, and establishing a patient/disease oxygen therapy target upon admission is considered best practice.

The COVID-19 pandemic has led to an increased demand for mechanical ventilators and concerns of a ventilator shortage. Several groups have advocated for 1 ventilator to ventilate 2 or more patients in the event of such a shortage. However, differences in patient lung mechanics could make sharing a ventilator detrimental to both patients. Our previous study indicated failure to ventilate in 67% of simulations. The safety problems that must be solved include individual control of tidal volume (VT), individual measurement of VT, individualization of PEEP settings, and individual PEEP measurement. The purpose of this study was to evaluate potential solutions developed at our institution. ⋯ The results of this simulation-based study indicate that devices for individual control and display of VT and PEEP are effective in extending the usability and potential patient safety of multiplex ventilation.

Face coverings are recommended to help mitigate the spread of COVID-19. Guidelines regarding face mask use have evolved from the time when COVID-19 first emerged. Practices for face mask use in the United States vary widely. ⋯ Practices and perceptions of face masks varied among staff in a pediatric health care system. Some staff did not feel that masks are effective in preventing virus spread, and others did not feel safe in performing job duties. Hand hygiene for mask handling was not practiced consistently. A large number of staff reported having experienced challenges or health issues when wearing a mask. Clinical staff who provide direct patient care reported more issues than both nonclinical and clinical staff who do not provide care.

Review
Upper Airway Assessment and Responses during Mechanically Assisted Cough - A Narrative Review.
When the ability to cough is impaired, secretion clearance may be assisted and augmented with mechanical insufflation-exsufflation (MI-E). In some individuals, the efficacy of MI-E may be hampered by counterproductive upper airway reactions, where the airways close in response to positive pressures. ⋯ There is increasing interest in monitoring and measuring upper airway responses to MI-E and how such information can be used to optimize MI-E settings. The purpose of this narrative review is to increase the theoretical understanding of the larynx as a respiratory organ, summarize the current literature in the area, and provide insight into how this knowledge can affect current clinical practice.
