摘　　要：目的:在研发便捷式呼吸器的基础上,对治疗呼吸衰竭的几种呼吸模式作了改进,增强了氧疗和通气的效果。方法:对COPDⅡ型呼吸衰竭清醒患者改用鼻罩式NEEP呼吸模式,取消手控管,用口吸气,用鼻呼气;对非典型Ⅰ型呼吸衰竭,在面罩正前方加一个呼气通道,呼气过程中空心球内可从球底部供氧管获得氧气,作为下次吸气时的储备氧气。结果:COPD患者因不受手控管的限制,呼吸更加规律、自由,有利于改善通气;对非典型Ⅰ型呼吸衰竭因不需要、也不会像Ⅲ式那样重复吸入CO2,也增加了FiO2。结论:根据病情需要可选择任意的FiO2,达到真正意义上的按需给氧目的,也可排出多余的CO2,有利于病情逆转。Objective To improve the ventilation mode for respiratory failure based on the self-made respirator, Methods For the conscious COPD patients with type II respiratory failure, nasal mask and NEEP ventilation mode were used. Patients breathe in air through the mouth and breathe out through the noses. There is no need of manual control tube to control the negative pressure in the nasal mask. For the non-typical type I respiratory failure, exhaled gas comes out from the one-way channel in the front of the mask, while oxygen for the next breathes is brought into the ball through the tube under it. Results The COPD patients breathe more freely and smoothly without disturb of the manual control tube. On the non-typical type I respiratory failure, FiO2 is much higher and without breath in CO2. Conclusion The new ventilation mode can provide a great range of FiO2 and get ride of redundant CO2. It＇s beneficial to the recovery of patients.[Chinese Medical Equipment Journal,2008,29（12） ： 64--66]
