Why my inert gaz method failed?

Hi,
I have tried two times to CTB thanks to exit bag and argon.
My exit bag seems to be fine, well sealed: i inhale argon during like more than 1 minute , but nothing happen. Just a headache.

Whats wrong ?

Is it all sealed perfectly?

Is it all sealed perfectly?

The bag is not too tight on my neck: I have set a little gap between the bag and my neck (1 finger large) because the CO2 i exhale need to go outside the bag,i guess its the right thing to do.

@gregisss What did you set the flow rate to?

@gregisss What did you set the flow rate to?

15liters/minute

@gregisss Did you scrunch the bag, before turning on the gas, to get rid of all the oxygen? And also breathe out before placing the bag on over your face?

are you using an argon regulator? you need to be more than one minute inhaling argon... it takes 15 minutes - 25 minutes the book says
