With just a few taps, users have access to all the necessary data to care for a pediatric patient in the emergent setting, including weight-based and age specific medication dosages and equipment sizes. Since many of the patients present with minimal known information, all the results can be calculated rapidly with only a known age, date-of-birth, weight, length, or height. Simply enter the known variable and the data is instantly calculated. Developed by an Emergency Physician, this app minimizes the risk of medical errors allowing the provider to spend more time caring for the patient, and less time looking up and calculating doses. It is a critical companion for any physician, nurse, paramedic, or medical trainee involved in the care of critically ill pediatric patients.
