A device for holding a nasal cannula on a patient includes a band formed of a generally flat strip of material, a first pair of fasteners at a first lateral side of the band for releasably securing one of the medical tubes to the band, and a second pair of fasteners at a second ...
A nasal cannula for inclusion in medical apparatus that delivers a breathable gas mixture of helium and oxygen to a patient comprises a length of high pressure narrow bore tubing having a proximal end region for connection to a high pressure source, a cylinder , of the breathable gas mixture ...
cannula having an enlarged orifice for delivering a stream of oxygen to a patient's nasal passages. The cannula structure has means for directing substantially the entire stream of oxygen toward the patient's nasal passages and has means for maintaining it in a proper position on the patient.收...
摘要:A nasal cannula arrangement for use as part of systems for delivery respiratory gases to a patient is disclosed. The nasal cannula arrangement includes a manifold part adapted to receive gases from a delivery conduit. The manifold includes one but preferably a pair of prongs extending ...
Under a Creative Commons license open accessAbstract Necrosis to cosmetically vital anatomical regions of the nose like the columella and the ala can occur after prolonged use of nasal cannula in neonatal patients. Nasal injuries following nasal cannula use occur when the nasal cannula providing oxygen...
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) and noninvasive ventilation (NIV) have been used for the treatment of COPD and respiratory failure in clinical settings. We aimed to evaluate the efficacy and safety of HFNC therapy in patients with COPD and type II respira
In the recent years, High-Flow through Nasal Cannula (HFNC) has been introduced in the clinical practice. HFNC delivers to the patient heated humidified air-oxygen mixture, with an inspiratory fraction of oxygen (FiO2) ranging from 21 to 100% and a flow up to 60 L/min through a large...
High Flow Nasal Cannula: What’s the Difference? Conventional preoxygenation is used before a patient is intubated using a nasal cannula or mask and can deliver up to 15 liters of oxygen per minute. This amount of oxygen is much lower than the necessary amount patients with respiratory ...
1. A cannula assembly comprising: a) an oral-nasal cannula disposable on the face of a patient and including a respiratory-gas-sampling nasal prong and a respiratory-gas-sampling oral prong; and a) a slidable tube slidably connected to one of the respiratory-gas-sampling nasal and oral pron...
