The economic impact of the introduction of home blood pressure measurement for the diagnosis and treatment of hypertension.
To investigate the economic consequences resulting from introduction of home blood pressure measurement in diagnosis of hypertension instead of casual clinic blood pressure measurement. ⋯ The introduction of home blood pressure measurement for the diagnosis and treatment of hypertension would be very effective to save costs.

Extracting oscillometric pulses from the cuff pressure: does it affect the pressures determined by oscillometric blood pressure monitors?
Oscillometric noninvasive blood pressure measurement devices determine the pressures by analysing the relationship between the pressure in an occluding cuff and low-amplitude pressure pulses (oscillometric pulses) induced in the cuff by the arterial pressure wave. This paper examines the effects on the pulses and oscillometric pulse amplitude envelope of the filters that extract the pulses from the cuff pressure. ⋯ The filter alters the shape of oscillometric pulses causing a shift in the oscillometric pulse amplitude envelope drawn from the filtered pulses compared with that drawn from the unfiltered pulses in human subjects, but not the test simulator. The pulse shape distortion is dependent on the filter characteristics and the oscillometric pulse shape. Further work is required to explore whether this may help explain why simulators with artificial waveforms cannot validate noninvasive blood pressure monitors and why noninvasive blood pressure monitors may not be accurate in all patient groups.
