YAKIMA, Wash. -- A 15-year-old Eisenhower High School student is in satisfactory condition today in a Tacoma hospital, days after a Friday collapse which required CPR and the use of an AED machine.

Charles Hanson is up, walking around, eating normal, and "itching to be released," said Yakima School District spokeswoman Kirsten Fitterer in a news release. However, testing is supposed to continue today in Mary Bridge Children's Hospital, in Tacoma, where he is currently. 

An update Friday originally said Hanson was in Seattle Children's Hospital.

On Friday, Charles collapsed at lunch soon after doing four pull-ups at a U.S Marines recruiting chin-up challenge station. Upon completing the workout, he walked away with his friends but then suddenly collapsed.

Ike security staff member Anothony Stewart and school resource officer Angie Neilson had to perform CPR and use the AED machine to shock his unresponsive heart. According to the news release, EMS was at the scene within three minutes and took over; doctors say it was the quick response of the onsite staff that was critical.

Principal Jewel Brumley called everyone involved heroes.

Hanson has not had prior medical issues and has played sports all of his life, said the news release. He is on the Ike junior varsity football team.
