This app can be used for some regular calculation of a clinical perfusionist. This app is easy to use. I hope it would be handy and useful for both practicing perfusionist and student. List of parameters can be calculated: 1. Body Mass Index, 2. Body Surface Area, 3. Flows according to Weight and Cardiac index, 4. Blood Volume, 5. Cardio Pledgia Information, 6. Circulating HCT and Oncotic pressure etc.
