高频射流通气(HFJV),是一种新型的机械通气方法。它在支气管镜检查术、喉部手术等方面的应用效果已被肯定,而在慢性阻塞性肺疾病(COPD)呼吸衰竭时的应用,尚有争论,本文旨在探讨COPD低氧血症病人的HFJV应用情况。对象与方法对象住脘的部分COPD低氧血症患者计先天性多发性肺大泡并阻塞性肺气肿1例,支气管扩张阻塞性肺气肿肺心病2例,慢性支气管炎阻塞性肺气肿肺心病21例。其中男19例,女5例,年龄22～81岁,平均63岁。方法 24例患者入院后常规给予抗生崇、祛痰剂、支气管扩张剂,部份心衰病人给予强心剂、利尿剂、扩血管药物(酚妥拉明、硝普钠等)。持续低流量吸氧处理后,复查动脉血气分析仍有血气显著异常,即予HFJV治疗。其中属Ⅰ型呼衰8例(PaO_2
High-frequency jet ventilation (HFJV), is a new type of mechanical ventilation method. Its effect in bronchoscopy, laryngeal surgery and other aspects of the application has been affirmed, and in chronic obstructive pulmonary disease (COPD) respiratory failure, there are still controversial, this paper aims to explore the COPD patients with hypoxemia HFJV application. Subjects and Methods Subjects living in part of COPD hypoxemia patients with congenital multiple bullae and obstructive pulmonary emphysema in 1 case, bronchiectasis obstructive pulmonary emphysema in 2 cases of pulmonary heart disease, chronic bronchitis obstructive pulmonary Pulmonary heart disease in 21 cases. Including 19 males and 5 females, aged 22 to 81 years, mean 63 years. Methods Twenty-four patients were given anti-parasitic, expectorant and bronchodilators routinely after admission. Some patients with heart failure were given cardiotonic agents, diuretics and vasodilators (phentolamine, sodium nitroprusside, etc.). Continuous low-flow oxygen treatment, the review of arterial blood gas analysis is still significant abnormal blood gas, which is to HFJV treatment. Which is type Ⅰ respiratory failure in 8 cases (PaO_2
