Non Invasive Blood Pressure Measurement Techniques

Blood pressure fluctuation is the most common health problem in all human beings. It is the root cause of cardiovascular diseases. During the last decades noninvasive blood pressure measurement devices are more commonly used in the hospitals and home care for routine examinations and monitoring. Comparatively low prices, less complicated in use and automatic measurement features making these devices more popular. However, non-invasive measures devices have lower accuracy and yield small systematic differences in numerical results. In this paper we review recent developments in the methodology of non-invasive arterial blood pressure measurement .Noninvasive pressure measurement techniques include: Oscillometry, Auscultation, Doppler ultrasound, Palpation. Particular importance will be placed on describing the methods’ strong and weak points .The noninvasive auscultatory measurements are quick and simple, and give less strain to the patient. Require less expertise in fitting, have virtually no complications, and are less unpleasant and painful for the patient.
