The information button gives you the range calculation. A nicardipine infusion range is also given for the treatment of severe hypertension.

EMS Guidebook allows the user to view the medical protocols of specific EMS agencies. This guidebook is meant to be a replacement of the traditional flip book guides that EMTs and Paramedics carry for reference on emergency calls. The specific agencies protocols require passwords to download. Those passwords are available from the agency's Training Officer. The Generic Protocols are available without a password. As part of the base program, each set of protocols contain references such as pediatric vital signs, burn references, c-spine clearance charts, 12-lead guidelines, American Heart Association (AHA) guidelines, START and JumpSTART triage guides. There are also guides to several common cardiac rhythms with examples. If you wish to have your protocols put into this system contact us through the app

Verdict
The clearest difference is price: EMS Guidebook at Free against EMS Calculator's $0.99. EMS Guidebook also leads on rating (4.9 vs 1.8) and ratings volume (115 vs 4). EMS Calculator's advantage is in-app purchases (none vs 7) and iOS requirement (6.0 vs 15.0). On ads and device support there is nothing between them.
