OBJECTIVE
The study investigated the feasibility and potential outcome measures during acute hyperoxia in type 2 diabetes patients (DM2).
METHODS
Eleven DM2 patients (7 men and 4 women) were included in the study. The patients cycled (30 min at 20% Wmax) whilst breathing three different supplemental oxygen flows (SOF, 5, 10, 15 L min(-1)). During hyperoxic exercise, arterial blood gases and intra-arterial blood pressure measurements were obtained.
RESULTS
Arterial pO2 levels increased significantly (ANOVA, p < 0.05) with SOF: 13.9 ± 1.2 (0 L min(-1)); 18.5 ± 1.5 (5 L min(-1)); 21.7 ± 1.7 (10 L min(-1)); 24.0 ± 2.3 (15 L min(-1)). Heart rate (HR) and pH increased significantly after terminating administration of hyperoxic air.
CONCLUSIONS
An SOF of 15 L min(-1) appears to be more effective than 5 or 10 L min(-1). Moreover, HR, blood pressure, blood lactate and pH are not recommended as primary outcome measures.
目的
本研究调查了2型糖尿病患者（DM2）在急性高氧期间的可行性及潜在的结果指标。
方法
11名DM2患者（7名男性和4名女性）纳入本研究。患者在呼吸三种不同补充氧气流量（SOF，5、10、15 L min⁻¹）的同时进行30分钟的骑行运动（强度为最大摄氧量的20%）。在高氧运动期间，测量动脉血气和动脉内血压。
结果
随着SOF增加，动脉血氧分压水平显著升高（方差分析，p < 0.05）：13.9 ± 1.2（0 L min⁻¹）；18.5 ± 1.5（5 L min⁻¹）；21.7 ± 1.7（10 L min⁻¹）；24.0 ± 2.3（15 L min⁻¹）。停止给予高氧空气后，心率（HR）和pH值显著升高。
结论
15 L min⁻¹的SOF似乎比5或10 L min⁻¹更有效。此外，不建议将HR、血压、血乳酸和pH值作为主要结果指标。
