Last summer I had an experience with my niece that supported
Shetining claim that you can stop an ongoing asthma attack
with this exercise. I did it before with my daughter too, but this
is another data-point.
Basically we were visiting our grand-parents in the village,
and my nice (10 years old) is allergic to something out there.
We never figured out what it is, but effect is very strong.
Remarkably, she does not get otherwise any asthma attacks, but in
that place she got massively congested and wheezy already in the
evening we arrived. In the night it developed into full-blown attack
with continious wheezing, panic and not getting enough air.

As we were in the middle of nowhere without any medications
there was nothing else to do but to try Strelnikova exercies.
Notably my niece never did it before. I was basically showing
her what to do and she was following my example doing push-downs
(pump, exercise 3), hug the shoulders (exercise 5) and push-and-hugs
(exercise 7). That is what Shetining recommended to stop the attack.
We were doing each exercise 80 sniffs, and than going to the next.
After going through each of thw 3 exercises twice, audible wheezing
stopped and breathing improved enough that she could sleep.
I was very relieved to see how well it worked.

Of cause it is better to prevent attacks altogether but doing
the full exercise every day (as we do with my daughter), but I think
it is useful to know what do if attack comes and you have no
bronchodilator handy.
