More importantly, if Ouyang Lei's heart rate ever goes past 200, then they can directly conclude he's simply not suited for this kind of spaceflight.
They can just Pass him right out of the selection.
Luckily, at this moment Ouyang Lei's vital signs have more or less recovered, at least they're showing a clear downward trend.
That makes it even more certain that he really might be able to adapt to this environment.
As for why things spiked so suddenly before, that's a perfectly normal human reaction.
As long as he can come back from that threshold, then you can say his body passes the standard.
Even those excellent astronauts will see their numbers shoot straight up going through this phase.
Their heart rate can easily double compared to normal.
There's no changing that.
In this world, there is no one who can stay in this flight condition with "no red face, no racing heart."
