冷热气温度试验,较之冷温水检查有以下优点:(1)刺激温度容易选定;(2)慢性中耳炎的患耳亦能进行;(3)给被检者带来的不愉快感觉较小;(4)检查技术简单易行,由于检查者带来的技术误差亦较少。作者使用冷热气刺激器,对15名正常人(男7人、女8人)进行了冷热气试验。刺激条件是冷气24℃、热气50℃(外耳道温度为30℃和44℃),送气6l/分,刺激时间60秒;并与30℃及44℃的冷热水(50ml/20秒灌完)的温度试验结果做了比较。眼震反应是以眼震数、反应持续时间及最大眼球速度(慢相)三项指标进行评价。眼震反应左右差用CP(半规管轻瘫)及DP(优势偏向)计算。眼球运动都以ENG描记法记
Cold and hot air temperature test, compared with cold and warm water check has the following advantages: (1) easy to select the stimulus temperature; (2) chronic otitis media in the ear can also be carried out; (3) to the seized person to bring a sense of unpleasant ; (4) inspection technology is simple, due to the technical errors caused by inspectors is also less. The author used hot and cold gas stimulator, 15 normal people (7 males, 8 females) were hot and cold gas test. The stimulation conditions were air-conditioned at 24 ° C, hot air at 50 ° C (external auditory meatus temperature of 30 ° C and 44 ° C), aspirated at 6 l / min for 60 seconds, and incubated with hot and cold water of 30 ° C and 44 ° C The temperature test results are compared. Nystagmus response is based on the number of eye Nymph, the duration of the reaction and the maximum eyeball speed (slow phase) three indicators for evaluation. Nystagmus left and right difference with CP (semicircular canal paresis) and DP (dominant bias) calculations. Eye movements are recorded by ENG description
