| Description
| - Automatic monitors for the determination of blood pressure frequently use the oscillometric method. Amplitudes of arterial pulsations evoked in the cuff are evaluated by software algorithms in order to determine the systolic and the diastolic pressures. The arterial pulses in the cuff are commonly called oscillations. Almost no attention has been paid to the contours of these pulses. Our objective was to demonstrate visually and numerically that the contours of pulses in the cuff are hemodynamic arterial waveforms rather than oscillations. We designed and constructed an experimental notebook-based system for wrist cuff and finger photoplethysmograph data acquisition and processing. The contours of wrist cuff pulses acquired at the point of diastolic pressure were compared to radial artery pulses acquired by other methods. Visual and numeric comparison revealed that wrist cuff waveforms are closely related to other hemodynamic waveforms acquired invasively and non-invasively. Comparison with age related waveforms acquired by applanation tonometry revealed similar prolongation of upstroke time with age. Values of left ventricular ejection time computed from wrist cuff waveforms obtained from 12 volunteers were close to normal values (0.6%). Our conclusion was that the wrist cuff waveforms are not oscillations and that they belong in the family of hemodynamic waveforms. We proposed new, more accurate terms %22cuff-pulse method%22 in place of %22oscillometric method%22 and %22cuff pulses%22 in place of %22oscillations%22.
