That makes sense.
So why do they teach dil flushes as the first-line-of-defence measure??

Not all do. My first reaction is to go to bail out. See if a few breaths clears the situation, then get back on the loop & flush. Monitor it from there. If it comes back, stay on bail out & turn the dive. If you feel fine, it's up to you... stay or go.
