The app helps practical physicians to calculate some important numbers which are used in clinical practice.  Infusion rate is calculated to get the exact value of different drugs infused by syringe pumps as ml/h while targeting any definite dosage in mg/kg/min, mg/kg/h, mcg/kg/min, mcg/kg/h.  Oxygenation index, ventilatory ratio and oxygen saturation index help to estimate the severity of lung injury level when providing mechanical ventilation for patients with lung diseases. Glomerural filtration rate provides the data regarding renal function.
