In an ideal world it would be advantageous to have widespread CPR training for the whole country. Such a program would save many lives each year in Canada. Unfortunately at the moment it is unknown just how long trained rescuers in CPR remember the course information. Some recent literature indicates that many necessary skills of CPR and first aid are forgotten shortly after certification in laypersons.
A recent investigation by WorkSafe BC set out to determine CPR retention rates and made some key findings:
- Many skills deteriorate rapidly over the course of the first 90 days.
- Repetition (the number of times trained/certified in First Aid or CPR) may be more important to skill retention than the length of time since the last training.
- A number of skills were performed poorly regardless of how much time had passed since the last training.
- Simple and cost effective updating strategies for first aid and CPR are needed to reduce the rate of knowledge and skill deterioration.
WorkSafe’s conclusions suggest that it may be more important to have repeated refresher courses about every 90 days. Individuals who had renewed their certificate more than once managed to score higher on their exams. Repetition seems to be the key to continuing CPR education.
Recently Iridia created a CPR quiz. We wanted to highlight the importance of knowing how to perform CPR correctly. We asked ten basic CPR questions that anyone trained in CPR should be able to answer correctly.
Here are the questions for those of you who did not complete the quiz.
1. What does CPR stand for?
2. CPR can be performed with chest compressions only.
3. Sudden Cardiac Arrest affects up to _____ Canadians each year.
4. The Heart and Stroke Foundations recommended optimum chain of survival is:
5. When performing CPR, the ratio of chest compressions to artificial respiration is:
6. When performing CPR on adults, the rate of compressions should be at least _____ per minute.
7. When performing CPR on adults, the compression depth should be at least _____ centimetres.
8. It is not recommended to perform CPR on children aged 6 and under.
9. As many as 85% of all Cardiac Arrests occur outside of a hospital.
10. Every minute of delay in CPR reduces the chances of survival by _____ percent.
The results of the quiz so far are not surprising, given the retention of CPR knowledge and lack of widespread training. The first graph charts the correct attempts for each question, while the second shows the quiz scores for each percentile.
With such a small sample of individuals who may or may not have CPR training it is impossible to make any strong conclusions; other than an average of 67% could be greatly improved.
