Would happen to an astronaut doing a space walk if his space suit was punctured by a tiny meteorite?

If an astronaut's space suit were punctured by a tiny meteorite, the immediate result would be a rapid loss of pressure inside the suit. This could lead to decompression sickness, hypoxia due to lack of oxygen, and exposure to the vacuum of space, which would be fatal within minutes. The astronaut would need to return to the spacecraft urgently or activate emergency protocols to mitigate the effects of the suit breach. Without a quick response, survival would be unlikely.
