Nasal cannula pediatric8/11/2023 However, patients were uncomfortable with 3 L/kg/min despite the same efficacy. Patients younger than 24 months of age tolerated the flow of 1–2 L/kg/min (up to 20 L/min) and 3 L/kg/min. Important randomized controlled studies conducted in patients with acute bronchiolitis provided information about appropriate flow. There is a lack of guidance about optimal flow in pediatric patients. Recent studies reported that limited pressure delivery of 2–4 cmH2O was measured in the pharynx and esophagus in children and adults with HFNC. In the experimental setting, positive lung-distending pressure increased as the flow increased from 0 to 12 L/min. Airway pressure generated from a high-flow system varies and depends on flow amount, cannula and nares sizes, and degree of mouth opening in an experimental study. The aforementioned principle, a higher flow setting than inspiratory demand, can be applied to patients of all ages. The development of clinical guidelines for HFNC, including flow settings, indications, and contraindications, device management, efficacy identification, and safety issues are needed, particularly in children.įlow setting and cannula size for pediatric patients Multicenter randomized studies are warranted to determine the feasibility and adherence of HFNC and continuous positive airway pressure in pediatric intensive care units. Several observational studies have shown that HFNC can be beneficial in acute asthma and other respiratory distress. HFNC can also reduce intubation and mechanical ventilation in children with respiratory failure. Randomized controlled studies suggest that HFNC can be used in cases of moderate to severe bronchiolitis upon initial low-flow oxygen failure. In children, flow level adjustments are crucial considering their maximal efficacy and complications. In preterm infants, HFNC can be used to prevent reintubation and initial noninvasive respiratory support after birth. The action mechanism of HFNC includes a decrease in nasopharyngeal resistance, washout of dead space, reduction in inflow of ambient air, and an increase in airway pressure. The definition of HFNC, how to set flow, and aerosolized medication delivery are areas in which more research is needed.Īerosol therapy children high-flow nasal cannula pediatrics.Ĭopyright © 2018 by Daedalus Enterprises.High-flow nasal cannula (HFNC) is a relatively safe and effective noninvasive ventilation method that was recently accepted as a treatment option for acute respiratory support before endotracheal intubation or invasive ventilation. Aerosols were delivered by 75% of respondents, predominantly via a vibrating mesh nebulizer placed on the dry side of the humidifier. There was no consensus on the definition of HFNC, how to set initial flow, or how to make adjustments. During aerosol therapy, 13% of respondents decreased HFNC flow, while 23% removed patients from HFNC. Aerosol therapy was delivered by 75% of respondents during HFNC, with 77% of these respondents delivering aerosol via vibrating mesh nebulizer. Noninvasive ventilation or CPAP was used by 88% of respondents as the next step for patients who failed HFNC, with 7% opting for intubation and 5% using other interventions. Initial flow was set per provider orders by 34% of respondents, per respiratory therapist-driven protocol by 28%, per patient weight by 15%, per patient age by 15% 5% of respondents used other methods. HFNC was defined as any heated gas delivered by nasal cannula by 49% of respondents, whereas 21% defined HFNC as heated gas delivered via nasal cannula at flow greater than or equal to the patient's inspiratory demand, and 16% defined HFNC as any gas delivered via nasal cannula above predefined thresholds. There were 63 responses, of which 98% used HFNC. Paper versions of the survey were also distributed at the annual Children Hospitals Association meeting. The goal of this study was to evaluate current HFNC practice by surveying practicing pediatric respiratory therapists.Ī survey instrument was posted on the American Association for Respiratory Care's AARConnect online social media platform in March 2017. In non-neonatal pediatric patients, there are limited data available to guide HFNC use, and clinical practice may vary significantly. High-flow nasal cannula (HFNC) use has greatly increased in recent years.
