Background
One problem with basic life support (BLS) and other types of training completed in one instructional session, with practice only at that time, is the performance skill may not be retained; when the skill is required later, individuals demonstrate a lower performance level (Luft & Buitrago, 2005). Basic life support training allows health care professionals and laypersons to perform CPR correctly in class, but skills need to be used or practiced to be retained.
