The article deals with The American Red Cross(Who) that is encouraging people to update on the cardiopulmonary resusitation(What). It tells us that"compression -only " CPR is an alternative when a responder is unwilling or unable to perform complete CPR( when).
Although it describes the procedure it does not really detail <em>how </em>to do it or <em>how</em> the The American Red Cross is planning on encouraging people to switch for this method.
Please explain or add more so i can answer
