The Franklin county Ohio Red Cross has online CPR classes, suppose they have us practice rescue breathing on the USB port?

The basic first aid, how hands on is it, do they go into things like splints where you need to do it by hand or is it all memorize this medicine for that symptom, i.e. would that be doable online, I was wanting to upgrade our home FAK but when I saw that class I decided to wait and take a class first so I'll know how to use things in it.
