经鼻导管高流量湿化氧疗(high-flow nasal cannula oxygen therapy, HFNC)2014年在中国内地开始应用,短短几年内在临床上得到快速普及推广,其临床疗效得到临床医生的广泛认可,国际著名杂志近些年来也相继发表了多篇大样本前瞻性临床研究,证...
呼吸衰竭是临床上常见危急症,经鼻高流量氧疗(high flow nasal cannula oxygen, HFNC)和无创通气(non-invasive ventilation, NIV)氧疗是治疗呼吸衰竭的重要氧疗措施。HFNC和NIV均可改善呼吸衰竭患者血气分析指标,并降低患者呼吸功。临床研究证实,HFNC治疗低氧性呼吸衰竭 效果与NIV相当,但HFNC治疗高碳酸性 呼吸衰竭效果有...
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...
The efficacy of high flow nasal canula oxygen therapy (HFNO) to prevent invasive mechanical ventilation (IMV) is not well established in severe coronavirus disease 2019 (COVID-19). The aim of this study was to compare the risk of IMV between two strategies of oxygenation (conventional oxygenatio...

The reason is that moderate or deeper sedation is required when using TOE because of its invasiveness, and if deep sedation is used, its respiratory depression becomes stronger and airway and respiratory management become unstable. High flow nasal cannula oxygen therapy (HFNC) is a device that ...

The nasal cannula plays an important role in the gas transmission of high-flow oxygen therapy through the nose , it can directly deliver a certain concentration of air and oxygen high flow gas to the patient through the nasal oxygen tube without sealing, and the gas temperature and humidity al...
Adults after cardiac surgery often suffer from various complications such as hypoxemia,lung infection and atelectasis. Therefore,oxygen therapy is usually needed to maintain adequate alveolar ventilation and oxygenation after extubation. High-flow nasal oxygen cannula( HFNC) has several features such as de...
