上海生产的小儿支气管窥镜的近端有一侧管用于输氧。在临床使用中,经该管输氧后,患儿常出现缺氧和紫绀。针对其不足,我们自制了定向输氧针,并对二者的通气量进行了测量比较。测量中,采用FJD80型单筒肺量计为记录仪,KRⅡ开放式喷射呼吸机为供氧机,通气频率为每分钟60次/分,驱动压力分别采用每平方厘米0.3、0.4……1.5公斤,按图1所示连接。 The proximal end of a pediatric bronchoscope produced in Shanghai is used for oxygen delivery. In clinical use, the oxygen in the tube, the children often appear hypoxia and cyanosis. In response to its shortcomings, we made self-made directional oxygen needle, and measured the ventilation of the two were compared. Measurement, the use of FJD80 single cylinder spirometer as a recorder, KR Ⅱ open jet ventilator for the oxygen machine, ventilation frequency of 60 beats / min, the driving pressure were used per square centimeter 0.3,0.4 ...... 1.5 kg , As shown in Figure 1 connected.
