Abstract: A method includes receiving characteristics of a patient to be administered a sedative for a medical procedure. The method also includes selecting one of multiple models based on at least one of the characteristics and a sedation technique to be used. The method further includes calculating an index to the selected model using one or more of the characteristics. In addition, the method includes identifying a specified dosage of the sedative using the selected model and calculated index. The characteristics of the patient could include a height, weight, age, and race of the patient. Selecting one of the models could include selecting one of the models based on the patient's race and the sedation technique. The models could include different models associated with different sedation techniques. Calculating the index could include multiplying the patient's height by the patient's weight and dividing a resulting product by the patient's age.
