Transconjunctival oxygen tension (PcjO2) has been used clinically in human beings and experimentally in dogs to evaluate tissue perfusion and to estimate arterial O2 tension (PaO2); however, normal values in awake healthy dogs have not been reported. In this study, transconjunctival oxygen tension and arterial oxygen tension were measured once a week in 6 healthy conditioned dogs (15 to 28 kg) for 8 weeks. The conjunctival oxygen index (PcjO2 index = PcjO2/PaO2) was calculated. Mean PcjO2 index for all dogs was 0.47 +/- 0.08 (X +/- SD). The variability of repeated measurements on the same dog and between dogs was evaluated. A difference (P less than 0.05) in PcjO2 index among dogs was evident, and although there was not a difference in the same dog over time, there was a high coefficient of variability.
经结膜氧分压（PcjO2）已在临床上用于人类，并在犬类实验中用于评估组织灌注和估计动脉氧分压（PaO2）；然而，清醒健康犬的正常数值尚未见报道。在本研究中，对6只健康的条件犬（体重15至28千克）每周测量一次经结膜氧分压和动脉氧分压，持续8周。计算结膜氧指数（PcjO2指数 = PcjO2/PaO2）。所有犬的平均PcjO2指数为0.47±0.08（X±SD）。评估了同一犬重复测量之间以及不同犬之间的变异性。犬之间的PcjO2指数存在差异（P＜0.05），尽管同一犬随时间没有差异，但变异系数较高。
