It's 101 degrees in Fresno (if not right now, just give it a day or two) -- and that means it's swimming season.

So how many plan to cool off by taking a dip in a pool or lake? My guess is thousands in the San Joaquin Valley.

But how many are certified in CPR -- and remember what to do -- should someone need help?

Every year children drown.

Children's Hospital Central California in Madera County saw 53 children with water-related injuries in 2008 -- about 70% from pool accidents, according to a story in The Bee this February. Of those, 40 recovered completely, three suffered some degree of brain damage and 10 died.

Knowing CPR can save a child's life. But how recently a rescuer took CPR (cardiopulmonary resuscitation) was one of the variables that made a difference in the outcome, according to Mary Jo Quintero, a nurse in the hospital's emergency department. The size of the child, water temperature and length under water were also factors.

The Fresno-Madera Red Cross hopes to increase the numbers of parents who can respond to a water emergency. The agency, with help from First Five Fresno County and the Fresno Parks and Recreation Department, is offering a free infant and child CPR class on July 18 at the Mosqueda Center, 4670 E. Butler Ave.

Classes are available in English and Spanish.

It might be the best summer-school class anyone could take. To reserve a spot in the class: (559) 455-1000.
