Product picture 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...
The invention relates to a high-flow nasal cannula allowing an increased supply of oxygen flow compared to nasal cannulas that already exist on the market. To this end, the nasal cannula has a connection to an oxygen supply source from which a conduit extends, said conduit branching into two...
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...
This randomized clinical trial compares the efficacy of high-flow nasal cannula oxygen vs standard oxygen therapy in reducing the rate of mortality at day
HNFC: High Flow Nasal Cannula As a non-invasive respiratory support ventilation mode, HNFC has the advantages of simple operation, good patient comfort, easy nursing, and low risk of nasal mucosa and nasal septum damage, and at the same time avoids ventilator-related lung injury ca...
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 ...
It has conventionally been delivered using nasal cannula or masks, therefore the maximal oxygen flow rates that these devices can deliver are limited to up to 15 liters per minute, which is far lower than the failure or difficult intubation. Ambient air dilutes the supplied oxygen, causing a ...
In recent years, High-Flow through Nasal Cannula (HFNC) has been introduced in the clinical practice. We designed the present systematic review of the literature to assess all effects of HFNC use reported in exacerbated COPD patients. In this setting, HFNC is able to keep PaCO2 unmodified, ...
