高频通气(HFV)是呼吸系统疾病治疗上的一项新技术。成人机械通气频率在60次/分以上者称为HFV。由于它具有潮气量小(小于解剖死腔)以及吸气时间短(0.001～0.1秒)的特点,以致吸气时气道峰压及平均气道压低,有利于静脉回流并减少肺动脉压上升,对血流动力学及心血管功能产生不利影响较少,因而受到人们的重视。为将这一新型通气方式应用于儿科临床,我们在动物实验后用于婴幼儿肺炎合并呼吸衰竭患者,取得了良好的疗效,现将结果报道如下。材料和方法呼吸机及其使用方法:1、呼吸机系江西第五机床厂生产的KR-Ⅱ型开放喷射式呼吸机。2、驱动氧压:根据我院麻醉科31例非胸腔手术病人的不同体重和使用HFV呼吸机时所应用的驱动氧压,计算
High frequency ventilation (HFV) is a new technology in the treatment of respiratory diseases. Adult mechanical ventilation frequency 60 beats / min or more known as HFV. Because it has a small tidal volume (less than anatomical dead space) and inspiratory time is short (0.001 to 0.1 seconds) characteristics, so that when inhaled airway peak pressure and mean airway pressure is conducive to venous return and reduce pulmonary artery pressure, It has less adverse effect on hemodynamics and cardiovascular function, which has attracted people’s attention. In order to apply this new ventilation method to pediatric clinic, we have obtained good curative effect after the animal experiment for infants and young children with pneumonia complicated with respiratory failure. The results are reported as follows. Materials and methods Ventilator and its use: 1, ventilator system Jiangxi Fifth Machine Tool Plant production KR-Ⅱ open jet ventilator. 2, Oxygen pressure: According to the anesthesia in our hospital 31 cases of non-thoracic surgery patients with different weights and the use of HFV ventilator when the driving oxygen pressure applied to calculate
