用面罩连到常规复苏器供氧,手指间歇密闭提供罩内正压法,可刺激婴儿自己的呼吸,这种方法安全,方便,容易掌握,便于学习,效果良好。方法观察对象是择期和急诊剖腹产的足月儿,如果Apgar评分少于6分且伴有窒息,即开始复苏。用一个标准圆垫面罩,在坚硬的有机玻璃上钻二个小孔。一个连到压力传感器,测量罩内压力;另一个连到提供斜侧吹开活瓣压气流的复苏器。可使面罩内压力达到30mmH_2O以内。一个水银呼吸速度描记器连到面罩正中孔,和不同压力的传感器联结来测呼气流量。压力和流量的信号都被放大和显示在双道描笔记录仪上。自流出曲线下的面积算出容量。用手指堵塞呼吸速度描记器的未端产生正压。面罩牢固的固定在
With the mask connected to the conventional resuscitator oxygen, intermittent finger closed cap pressure to stimulate the baby’s own breath, this method is safe, convenient, easy to grasp, easy to learn, good effect. Methods Subjects were full-term infants who were on elective and emergency cesarean section. Resuscitation was initiated if the Apgar score was less than 6 with asphyxia. Use a standard padded face mask to drill two holes in hard organic glass. One connected to the pressure transducer to measure the pressure in the hood and the other connected to a resuscitator that provides obliquely blown-up valve pressure airflow. Can make the pressure within the mask up to 30mmH_2O less. A mercury pneumotachometer connected to the mask center hole, and pressure sensors connected to measure the expiratory flow. The pressure and flow signals are magnified and displayed on the dual channel pen recorder. The area under the outflow curve calculates the capacity. Clogged with your finger The end of the spirometer produces a positive pressure. The mask is firmly fixed on
