The sheriff's office said faculty members, a school nurse, and a school resource officer quickly began lifesaving measures and used a LifeVac device to dislodge an obstruction in the student's windpipe."These situations are scary for everyone involved, and we are happy to partner with our great team at Odenville Schools to work together and help each other in times of distress," Sheriff Billy Murray said.In a statement from Megan Messick, mother of the student, Grayson Messick, she said they "almost lost him.""They couldn't get it up with the Heimlich, and he started turning blue," Messick said. "Then his science teacher saved him with her personal LifeVac by sucking the orange out." Messick said paramedics arrived as the device was being used. She said they then rushed Grayson to Children's of Alabama because of a lack of oxygen and because he was coughing up blood.Thankfully, though, his mother said he has been released from the hospital and has made it home safely.She said his oxygen levels were good when they left. He does have an edema on his lung but, at this point, hasn't had any more fluid buildup.She said they'll continue watching him at home and added that Grayson could be back in school as soon as Monday.St. Clair County Schools and the sheriff's office are working to have the device called LifeVac available in the schools and with deputies soon.Arthur Lih, the CEO and inventor of LifeVac, said Grayson's life is one of many saved because of the device."We've saved almost 2,000 people, over 1,100 children," Lih said. "I think we have about 20 school saves now."
