This work aimed to show the application of the charts control for individual values in the health area . A case study was developed; it was composed by a Type II Diabetes Mellitus person who was in treatment. His values of the glicemy over fast were followed in the period of May 1 to August 16, 2006. The glicemy level of fast was tested every day in the same time in the morning. With these data, the application of the control charts of individual Xi was shown. The control charts of mobile range Rm for individual data, control chart for accumulated additions CUSUM for individual data and mobile averages control chart of exponentially weighed EWMA for individual data to monitore the glicemy of fast of the described patient was demonstrated. It was concluded that under the point of view of the treatment, a higher adequacy of the dosage of insulin in the treatment is possible when related to the control of the variation of the glucose taxes. It is caused by the reduction in the sampling tax when the chart indicates a process under control. It is noticed that, although the difference between the average sample required for chart CUSUM, EWMA and the chart of Shewhart to emit signal out of control (ARL) can seem small, the economy provided for chart CUSUM and EWMA can be significant when it is used for a long period of time.
