Pocketable Backup
Format: Paperback
OK... No computer, No Cell Service, No Electricity, No WiFi, No Radio, Oh My God... No Kindle... RATS!
Let me see... There it is... My Emergency & Critical Care Pocket Guide... YEP!
Even stagnating in the bottom of your bag its reassuring to have a backup...

Great info TINY BOOK
Format: Paperback
There’s small, and then there’s this book. It’s true that this is a pocket size book. Look at the dimensions and then imagine 6pt font. Giving it four stars because info is great- succinct, useful, and up to date! But taking away one star because it should come with a magnifying lens.

Army Medic Emergency Reference
Format: Paperback
Great book for a field medic for emergency conditions. It fits nicely in my aid bag. The only issue I had with the actual book is it was bent on arrival

Not helpful for new grad
Just random facts
No abdominal pain test panel/plan for example. An emed book should have basic guidelines for most common chief complaints
