Using the System
* Put on the pulse Oximeter and wait for it to get a reading.
* If you're using the ball valve, close it completely.
* Start a timer (or use the [[Hypoxic Timer]] software).
* Start breathing through the mouthpiece. It will take a minute or two for the oxygen in the bag to drop, and your [[SpO2|SpO<sub>2</sub>]] drop will lag behind that.
* Once your [[SpO2|SpO<sub>2</sub>]] drops, but before it reaches your target you will need to start mixing some room air into the system. You can either do this by cracking open the ball valve slightly or by taking a partial breath from the room. You will need to find the right balance of room air to rebreathed air that will keep your [[SpO2|SpO<sub>2</sub>]] near your target based on trial and error. This is takes some practice to get right, but it a lot easier with the ball valve.
* Once your time is up, remove the mouthpiece and breathe room air. After the recovery period, restart the hypoxia and repeat the appropriate number of intervals.
* Some guidance on IHE plans can be found at [[Intermittent Hypoxic Exposure]].
 
=After Use=
After you've finished using the system, disconnect the parts to let them dry out. However, the hypoxicator should not be dried out as moisture is part of the CO2 scrubber. You should check the color of the CO2 scrubber immediately after use as it will turn purple when it's exhausted, but the color will fade.
