Nasal cannulaHelioxPEEPUpper airwaysHigh flow nasal cannula therapy is a form of respiratory support which delivers high flow rates of heated, humidified gas to the nares via specialized cannula. Two primary mechanisms of action attributed to the therapy are the provision of positive airway pressure ...

High-Flow Nasal Cannula (HFNC) is a heated and humidified system that allows oxygen (FIO2) levels to be delivered at very high flow rates.
该共识主要针对经鼻高流量氧疗(High Flow Nasal Cannula,简称HFNC)在临床麻醉中的应用进行了规范化指导,旨在提高患者的舒适度和治疗效果。 HFNC是一种高流量、低湿度的氧气输送方式,通过鼻腔或口腔将氧气输送到肺部。这种治疗方法具有较高的氧浓度,能够减少患者因吸入高浓度氧气而产生的不适感。同时,HFNC还能降低呼吸...
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...
Effects of high-flow nasal cannula on the work of breathing in patients recovering from acute respiratory failure[J]. Crit Care Med, 2017, 45(12):1981-1988. [6] Motoyasu A, Moriyama K, Okano H, et al. High-flow nasal cannula therapy reduced the respiratory rate and respiratory distress...
High-flow nasal cannula (HFNC) therapy has emerged as a promising support mode in the paediatric intensive care unit (PICU), but no data are available on HFNC used during interhospital transport. We aimed to assess the safety of HFNC during retrievals of critically ill children and its impact...
High-flow nasal cannula ventilation therapy The next day after the titration study, participants began the HFNC treatment for one week in the ward. The HFNC flow rate was kept constant without ramping every night and the beginning flow rate on the first night was set at 20 L/minute. On ...
OBJECTIVE: To measure the intrapharyngeal pressure (IPP) generated by high-flow nasal cannula (HFNC) at varying flow rates up to 5 l min(-1). STUDY DESIGN: We studied 14 infants on HFNC or NCPAP using IPP manometry to measure the IPP generated at flows of 1, 2, 3, 4 and 5 l min...
High-flow nasal cannula (HFNC) offers an alternative to other oxygenation therapies, including standard noninvasive positive pressure ventilation (NIPPV), and has been studied in diverse clinical settings. The HFNC system includes a flow meter, an air-oxygen blender, a humidifier, a heated circuit...
