  1. Sep 7, 2022 · High-flow oxygen therapy is the oxygen-delivering method of inspired fraction (FiO 2) up to 1.0 via a high-flow nasal cannula across a range of flows from 2 to 60 l/min. It also provides positive airway pressure and decreases rebreathing from anatomic dead space, which helps reduce the respiratory effort [ 14 , 15 ].

  2. Jun 29, 2017 · In this pilot study, we enrolled patients aged 1-14 years with asthma exacerbation who met at least 1 of the following criteria: moderate to severe respiratory failure, defined as a pulmonary score (PS) ≥6 (Table I; available at www.jpeds.com), 34 or the need for a high level of oxygen support (SpO 2 <94% with a face mask) despite initial treatment with nebulized salbutamol (<20 kg, 2.5 mg ...

  3. Feb 1, 2019 · Oxygen therapy with high-flow nasal cannula (HFNC) has proven to be a safe and effective technique in the management of bronchiolitis and asthma in children. 5, 6 It is considered an alternative to CPAP in patients with respiratory failure due to asthma or other diseases. 7 Treatment with HFNC reduces the dead space, improving CO 2 clearance, and produces a slight positive pressure at the end ...

  4. Nasal high flow (NHF) is another oxygen‐delivering method of inspired fraction (FiO 2) up to 1.0 via a purposely made high‐flow nasal cannula across a range of flows from 2 to 60 L/min. Conditioning of delivered gas by warming to 37° C and fully saturating with water offers patients comfort during the therapy while high flow provides positive airway pressure and decreases rebreathing from ...

  8. Mar 1, 2021 · Background: Asthma is the leading chronic disease in children. When children present with an asthma exacerbation (AE), they are frequently managed with steroids, bronchodilators, and oxygen support. High flow nasal cannula (HFNC) is a method of delivering inspired oxygen rapidly via nasal cannula. HFNC has become popular to use in pediatric AEs, due to its safety and convenience of use a ...
