Fig. 1. The high flow nasal cannula (HFNC) system incorporated an air/O2 blender with a flow meter and a heated humidifier. For the HFNC protocols, nasal prongs were connected to the manufacturer's standard circuit. We made 2 holes in a polyvinyl chloride cylinder to simulate adult external...
High-flow nasal cannula (HFNC) oxygen therapy delivers adequately heated and humidified medical gas up to a flow rate of 60 L/minute and has the following physiological effects: anatomical dead space reduction, positive end-expiratory pressure (PEEP) effect, constant fraction of inspired oxygen, ...
After delivery, the neonate was intubated due to signs of respiratory distress syndrome. On day 20, she was extubated and placed on a nasal cannula providing 35% FiO2 with a flow rate of 5 L per minute. The patient developed a progressive pressure wound of the columella 30 days later. ...
High-Flow Nasal Cannula Conventionally, oxygen is given at 4 to 6L/min through nasal cannula for supplementation of oxygen. The FiO2 achieved through this can be up to 0.4. Flows ... AF Sam,AY Yadav - 《Mechanical Ventilation》 被引量: 0发表: 2022年 Maintaining the status flow: high‐...
经鼻高流量氧疗(humidified high-flow nasal cannula,HFNC)由空氧混合器装置、主动加温装置、加热导丝单回路管路、鼻导管组成。HFNC可提供恒定的氧浓度以及最高可达60～80 L/min的流量,其输送的气体经过加温加湿,可达到37℃、100%的相对湿度。因此与传统氧疗比较,HFNC克服了湿化不足和氧浓度不稳定等局限,具有更...
High flow nasal cannula (HFNC) oxygen is an oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of 60 liters per minute and eventually higher.

Lin, Y.et al.High-flow nasal cannula oxygen therapy and hypoxia during gastroscopy with propofol sedation: a randomized multicenter clinical trial. Safety and effectiveness of propofol sedation during and after outpatient colonoscopy. ...
The high-flow nasal cannula (HFNC), a high-flow oxygen-generating device, delivers targeted FiO2and reduces the dead space with adequate positive end-expiratory pressure delivery, improving the ventilatory efficiency. We aimed to establish the efficacy of HFNC in the management of hypoxemic ...
High-flow nasal cannula (HFNC) oxygen therapy applied after extubation decreases respiratory rate (A), has no effect on tidal volume (B), it increases PaO2/FiO2ratio (C), and it did not modify arterial carbon dioxide levels (D), compared to standard oxygen. Horizontal red lines represent me...
