Teach Me is a practical fluid management app development project for healthcare professionals. The app supports adult and paediatric intravenous fluid therapy in hospital settings. It provides quick guidance on fluid classification, IV solutions, resuscitation, burns, surgery, maintenance therapy, and diabetic ketoacidosis. The app also covers paediatric resuscitation, maintenance, gastroenteritis, burns, and diabetic ketoacidosis. Healthcare professionals can use the perioperative fluid management algorithm to assess fluid and vasopressor needs. The algorithm uses clinical markers such as MAP and SVV. A built-in adjusted and ideal body weight calculator also helps with quick clinical calculations. This fluid management app development project combines clinical guidance and useful tools in one simple mobile app.
