CPR stands for Cardiopulmonary Resuscitation which is an emergency lifesaving procedure and is applied immediately when somebody’s breathing or heartbeat has stopped which has to be made to work by manually compressing the chest overlying the heart and forcing air into the lungs. It is used to maintain circulation when the heart stops pumping, usually because of disease, drugs, or trauma. This may happen after an electric shock, drowning or heart attack. CPR techniques also vary depending on the size and age of the patient. Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant).
