Bufo marinus which were exposed to a step increase of 330-350 torr O2 for a 20 h period ceased lung ventilations and buccal movements were markedly decreased. Toads which were sitting in water did not show elevations in PaCO2 or a depressed pHe but animals which were dehydrated for a 24 h period prior to high O2 exposure developed a mild acidosis, which, typical of most amphibian species, was uncompensated.
暴露于氧气分压逐步升高至330 - 350托持续20小时的海蟾蜍停止了肺通气，口腔运动也显著减少。处于水中的蟾蜍并未出现动脉血二氧化碳分压升高或血液pH值降低的情况，但在高氧暴露前脱水24小时的蟾蜍出现了轻度酸中毒，这是大多数两栖类物种的典型情况，且未得到代偿。
