Hi Skysista,
Iguagahead is correct in saying the Senior First Aid certificate course includes CPR. The SFA cert is valid for 3 years, CPR for one year. Its my understanding that you need at least 1 year validity on your SFA, and either 6 months or 1 year on your CPR?
If your SFA is still current for at least 1 year, I suggest you go do CPR refresher course (usually only 3 hours, about $45 or so??) - your CPR is then valid for the next year.
Cheers, and good luck!
