I just got this. I wish I had access to this when I was working, retired RN( active license) still like many, love to keep current. Having done so much in a long career ( like my wife) I was a Nurse before men were in the field. This has pharmacy information ( was at UConn in pharmacy school) before I dropped my 1-A, with a low draft number. Medic, changed after to Nursing with my wife. This has a wealth of information. OB-GYN( first male RN) early, decelerations) Point is I’ve never seen so much in one spot except PDR, or Taber’s.
I’ve had this app for years and use it often. From when I was flying, to my ER and ICU time and now in the cath lab. It’s a straight forward reference that has the info you want and quickly accessible without having to search through the app to find it. Visually it is easy to read and pick out what you need. Absolutely perfect app for emergency and ICU reference. It’s so smooth you can pull it up quickly in real time to if you just want to verify what you’re working on. Thank you so much for making this app and making it the way it should be. Keep up the amazing work.
I’ve been a full-time emt/Paramedic and a busy 911 system since 1995, and this app is one of my most used references in my pocket on duty and off. It always felt like most pocket guides from back in the day were geared more towards nursing and this app has everything an EMT/paramedic can use and reference as well as great nursing references and EMS type references. I would definitely recommend this app to anyone involved and emergency medical services whether you are with the ambulance company, fire department, emergency room, etc... you won’t be disappointed for the purchase.
