By Rose Dodson

It may sound complicated; however it’s actually quite simple. The same nitrous hood you use everyday can be adapted to monitor CO2. We’ll show you how.

 You will need only three items:

1. Nitrous Hood

2. 1/8″ Hole Punch Pliers (commonly used for crafts)

3. Nitrous Hood Adapter

First, use the hole punch or other cylindrical object to make a rounded hole in the nitrous hood near the top.  If you are using a hood with a liner,  then you will need to puncture through both the liner and the hood, as shown here.

You are now ready to attach your CO2 sampling line.  Attach the male luer lock end to the nasal hood adapter and the opposite end to the monitor.
