Atracheotomy is an emergent method in the treatment of the respiratory tract obstructionand in the improvement of oxygen circulation. it has been extensively applied in clinicalmedicine. subcutaneous emphysema and infection of the incisional wound are commoncomplications after tracheotomy. the causes for the complications are analysed and theincisional dressing change method after tracheotomy is improved to redue the incidence ofsubcutaneous emphysema and infection of noisional wound effectively
氣管切開術,做為臨床解除呼吸道梗阻,改善氧循環的一種急救技術,已被廣泛採用,但氣管切開術后發生的皮下氣腫及切口周圍感染是臨床常見並發癥,本文針對其發生原因進行了分析,探討了改進術后切口的換藥方式,有效的降低了皮下氣腫和感染的發生率。The main works are listed as follows : ( 1 ) based on the excitation of bi - directional current pulse technique, a new measuring circuit for weak variation of resistance was proposed for electrical resistance tomography. traditional ac current source is n ' t adopted as the exciting source. through fast bi - directional current switching, the polarization effects are eliminated
該電路主要優點如下:該電路沒有採用傳統的交流電流激勵法作為系統的設計原理,而是通過快速的正負極性電流切換來削弱直流電流激勵時激勵電極的極化效應,使通過直流法來測量氣液兩相流的電阻微弱變化成為可能。
