Oh yes! Ribbet! It kept me alive for 6 months before I was
on a vent. I would have died if I hadn't of tried it. It kept my
lungs stronger during the day and kept me breathing normal
when I would rest. My heart used to beat at 140 per minute.
Frog breathing would drop it to 70. I can frog breath on the
vent using a passy muir valve. It helps me slow down my tachecardia.
You should hear how loud my voice can get!
