My 2-year-old son choked on a large peppermint and was completely without air for at least a minute. Being cpr certified, I was unable to get it out. Just one pull from the lifevac and it was sucked right out. My son is alive today because of this product! JJ Brock This device saved my sons life. It was easy to use under the stress of our choking incident. My son is 15 months, he couldn’t breathe. After several back blows my husband used the LifeVac on our baby, his airway cleared. He is alive and well today because of this life saving device. I will forever recommend the LifeVac to every single person I know. Kristy O
