This year our care home requires to update our CPR techniques, and I require a course which will be convenient for our employees. I have already made some research regarding basic life support training Bristol. The course offered by different providers differs in many aspects. Some companies prefer to organize small groups and provide students with practical classes on dummies, others prefer to use only slide presentations. What is the proper course duration? Does the practical examination matter? I also need information regarding annual updates and rapid training of new staff members.
