Usable Design

Purpose
Blood pressure machine is suitable to be used for self testing by patients, to monitor blood pressure (systolic and diastolic) and pulse rate. The blood pressure measurement is obtained by the use of the oscillometric method, meaning that the monitor detects the blood's movement through the artery in the arm and converts the movement into digital readings. (No need of stethoscope and the expert's ear.)

Consideration
The blood pressure monitor is not suitable for people who have circulatory problems, such as arrhythmia. Heavy arteriosclerosis and other circumstances such as spasms in the arm may result in erroneous readings and prolonged measurement time, which may be considered more painful.
