Importance to renew CPR certification. CPR recertification is important when you would be surprised at how rapidly you may skip ways to perform CPR when you have recently passed through on-line CPR certification. The normal recommendation is that you must recertify every 2 years.
In the US the Red Cross CPR certificate is valid for about a year while the American Heart Foundation certificate is valid for two years. The first aid certificate is valid for three years. You can always recertify to retain the validity of your certificate.
