研究概览
简要总结
High-flow nasal cannula (HFNC) is a device that delivers10 to 70 L min-1 of heated, humidified 100% oxygen via nasal route. It provides positive airway pressure, decreases dyspnea, decreases the work of breathing, and improves comfort
详细描述
Beneficial effects of the HFNC system have been assessed based on 3 physiologic conditions: decreased dead space, a high concentration of inspiratory oxygen, and positive pressure in the oro-laryngeal cavity.Studies have shown that it improves oxygenation in various perioperative settings such as the apneic patients, patients with respiratory failure , and patients undergoing bronchoscopy
