The original Emergency Medical Services (EMS) Field Guide has grown into the most-used reference guide in EMS history. This is the guide that EMS Magazine calls “The original and still the best.” The 19th edition of the guide's Advanced Life Support (ALS) version has been updated with the new 2010 cardiopulmonary resuscitation (CPR) and advanced cardiovascular life support (ACLS) algorithms from the American Heart Association (AHA). This handy guide makes it easy for paramedics, nurses, and physicians to look up their patients' medications, check drug doses, quickly interpret 12-lead electrocardiograms (EKGs), and much more.
