To write a good patient note during your nephrology, cardiology, and pulmonary medicine rotations, you have to know the common medical formulas. The Calculate app from QxMD Medical Software will help you calculate:
- For Nephrology – eGFR with CKD-Epi, the Cockcroft-Gault equation, MDRD, anion gap, creatinine clearance, FeNa, and water deficit for hypernatremic patients.
- For Cardiology – the Framingham and Reynolds Risk Scores, CHADS2 score for atrial fibrillation, mean arterial pressure, LV stroke work, cardiac index, cardiac output, and the TIMI risk score.
- For Pulmonology – A-a gradient, ABG, pulmonary shunt, pulmonary vascular resistance, oxygen delivery, oxygen saturation, and lung volume.
