Hypoxicator

A hypoxicator is a special machine that helps people practice breathing in different types of air. The air we usually breathe has lots of oxygen in it, which helps our bodies stay healthy and strong. But sometimes people want to practice breathing in air that has less oxygen than usual. This can be helpful if they are going to be going to a place where there is less oxygen in the air, like if they are going hiking in the mountains.

The hypoxicator helps by taking in air from the room and using a special filter to take out some of the oxygen. Then, it gives the person using it the air to breathe in. This teaches the body how to use oxygen more efficiently, which can be very helpful if someone is going to be in a place where there isn't as much oxygen available.

Even though the air from the hypoxicator has less oxygen, it is still safe to breathe because it is filtered and the levels of oxygen are monitored. The hypoxicator is used by athletes, mountaineers, and sometimes even people with medical conditions that affect their ability to breathe in enough oxygen.
