Twelve volunteers were subjected to a double-blind crossover test to evaluate their concentration in conditions of hypoxemia after treatment with piracetam or with a placebo. Piracetam was administered in doses of 4.8 g per day for 4 days and 7.2 g on the 5th day. The speed with which the test was carried out was not influenced to a statistically significant degree but the proportion of errors was. This effect of piracetam was more pronounced for the longer-lasting periods of hyposemia.
12名志愿者接受了双盲交叉试验，以评估他们在服用吡拉西坦或安慰剂治疗后低氧血症状态下的注意力。吡拉西坦的给药剂量为每天4.8克，持续4天，第5天为7.2克。试验进行的速度没有受到统计学上的显著影响，但错误比例受到了影响。吡拉西坦的这种作用在持续时间较长的低氧血症期间更为明显。
