The article €œEstimation of Mean Arterial Pressure from the Oscillometric Cuff Pressure: Comparison of Different Techniques€ (D. Zheng, J. Amoore, et al., Med Biol Eng Comput, 2011:33€“39) describes a study comparing two methods of measuring mean arterial blood pressure. The auscultatory method is based on listening to sounds in a stethoscope, while the oscillatory method is based on oscillations in blood flow. Following are measurements on six subjects in mmHg, consistent with means and standard deviations presented in the article.
