39.有關高流量氧氣鼻管(HFNC)設備的敘述,下列何者正確?
(A)HFNC設備需要三個組件:①病人介面,如鼻管和輸送氣體的管路 ②調節氧氣濃度控制氣體裝置 ③主動 加熱型濕化器
(B)只要是中度缺氧病人皆可使用,不限定是否有自主呼吸
(C)氧氣流速每20 L/min大約可產生1 cm H2O的吐氣末正壓(PEEP)
(D)無法從解剖無效腔中沖走二氧化碳,因此不可用於高二氧化碳之病人

(A) All HFNC systems require three components: (1) a patient interface, such as nasal prongs, (2) a gas delivery device that regulates FiO2, and (3) a humidifier.
(C) generating a distending, positive end-expiratory airway pressure (PEEP) of approximately 1 cm H2O for each 10 L/min of flow.
(D) washout of carbon dioxide from anatomic dead space.
