The 18th edition EMS Field Guide ALS Version contains a newly updated drug section along with enhanced illustrations for a better understanding of the material. This 3"x5" pocket-sized guide has color-coded tabs so that paramedics, nurses and physicians can easily look up patients' medications, check drug doses, quickly interpret 12-Lead EKGs and review the latest CPR and ACLS algorithms from the AHA. All Informed guides are waterproof, alcohol-fast and 'street tough'. Digital and iPhone application versions of this guide are now available for use on both handheld devices and computers.
