Three types of commercially available caloric irrigation units--air, water, and closed-loop--were evaluated for nystagmus response patterns and comfort. Electronystagmographic recordings were analyzed for slow-phase velocity, response duration, amplitude, frequency, and test-retest reliability. Significant differences were found among the three types of irrigators, between warm and cool irrigators, and between male and female subjects. Test-retest reliability was adequate for all three units. Subjects clearly favored the closed-loop system over the water and air irrigators, but the water irrigator yielded the most robust caloric response.
对三种市售的热量灌注装置——空气、水和闭环式——进行了评估，以观察其诱发眼球震颤的反应模式和舒适度。对眼震电图记录进行分析，以测定慢相速度、反应持续时间、振幅、频率和重测信度。结果发现，三种灌注装置之间、温热与冷刺激灌注装置之间以及男性和女性受试者之间均存在显著差异。三种装置的重测信度均足够。受试者明显更喜欢闭环系统，而不是水和空气灌注装置，但水灌注装置产生的热量反应最为强烈。
