4. After 30 minutes, the rats were removed, cleaned of the experimental setup, wiped clean with 75% alcohol, and a second rat screening experiment was performed until the concentrations of O2 and CO2 in the hypoxia-sensitive individual screening experimental setup were restored to normal levels.
The experimental results are shown in fig. 4, and the cerebral edema model group has a slower rate of decrease in the concentration of O2 and a slower rate of increase in the concentration of CO2 than the control group. There are 3 parameters that can be used as the index of different hypoxia-sensitive population groups, and firstly, the brain edema model group has a slower rate of decrease of the concentration of O2 compared with the control group; secondly, the rising rate of CO2 in the cerebral edema model group is slower than that in the control group; third, the time lag for the brain edema model group to reach the intersection of the O2 concentration and the CO2 concentration was compared to the control group.
Example 2 screening of Small animals for hypoxia-tolerant individuals (rat as an example)
1. The SD rat as a qualified experimental animal is selected, male, purchased from a certain company, raised in a constant-temperature (23 +/-2 ℃) and constant-humidity animal room, and can freely eat and feed water in 12/12h day and night circulation every day. A company of a low-pressure and low-oxygen animal experiment cabin simulating plateau environment.

2. 10 rats were randomly divided into two groups, a control group and an intermittent hypoxic training group (IHT group), each of which was 5. The IHT group is placed in a low oxygen chamber for 4 hours every day, and parameters are set to simulate the altitude of 3000 meters in plateau, and the ascending speed and the descending speed are both 30 m/s. After 14 days of indirect hypoxia training, a hypoxia-sensitive individual screening experiment was performed.
3. Rats were placed in the hypoxia-sensitive individual screening test device while a timer was pressed and changes in the concentrations of O2 and CO2 on the display screen were recorded every 5 minutes.
After 4.30 minutes, the rats were removed, the experimental setup cleaned, wiped clean with 75% alcohol, and a second rat screening experiment was performed until the concentrations of O2 and CO2 in the hypoxia-sensitive individual screening experimental setup were restored to normal levels.
The results of the experiment are shown in FIG. 5, in which the IHT group showed a faster decrease in O2 concentration and a faster increase in CO2 concentration than the control group. There are 3 parameters that can be used as indicators for different hypoxia-sensitive groups, wherein, firstly, the IHT group has a faster decrease rate of O2 concentration than the control group; secondly, the rising rate of the concentration of CO2 in the IHT group is faster than that in the contrast group; third, the IHT group and the comparative group reached the time point at which the O2 concentration crossed the concentration of CO 2.
