Hypoxic Cycle Menu Settings
The user can set hypoxic cycle on the left side of screen 6. The timing values define how long the
Oxygen and Carbon Dioxide levels are maintained for once they have been achieved. This means
that there is a time period between the steps that cannot be set as it is dependent on the difference
between the set-points within the gas control software.
Pressing on any of the values will bring up a dialogue box to enter the required setting. If only 2
values are required for the cycling then set step 1 and 2 as required, then set step 3 times period to
0 minutes with the O₂ and CO₂ set
-points the same as step 2.
Once the setting is correct then press the start button to begin the cycling. At this point the start
button will change to a Stop button. The continuous cycling will stop by pressing the Stop button.
The left side of the screen is the current status of hypoxic cycle.
