Key result
Placement of the blood pressure cuff and sensor on the same arm versus opposite arms resulted in no significant difference in measured blood pressure or arterial elasticity indices.
Why the study?
Does placing the blood pressure cuff and sensor on the same arm versus opposite arms affect arterial elasticity and blood pressure measurements using the HDI/Pulsewave CR-2000 system?
Cross-Sectional (n=20)
Does placing the blood pressure cuff and sensor on the same arm versus opposite arms affect arterial elasticity and blood pressure measurements using the HDI/Pulsewave CR-2000 system?
The HDI/Pulsewave CR-2000 system can be used with the blood pressure cuff and sensor on either the same or opposite arms without significantly affecting measurements.
Allows either same- or opposite-arm placement for HDI/Pulsewave CR-2000 without affecting readings; leaves open generalizability beyond this cross-sectional sample.
BACKGROUND: Arterial elasticity is implicated as a risk factor for or a marker of cardiovascular disease. Current advances in non-invasive devices have now made it possible to measure arterial elasticity in an ambulatory setting. OBJECTIVE: The aim of this study was to determine whether there is a difference in blood pressure and arterial elasticity measured in the right and the left arms. METHODS: Simultaneous measurements were performed with two HDI/Pulsewave CR-2000 Research CardioVascular Profiling Systems. The manufacturer recommends placing the blood pressure cuff on the left upper arm and the sensor on the skin overlying the right radial artery. We followed the manufacturer's recommendations and also placed both the cuff and the sensor on the same arm. Simultaneous measurements were made on both arms with both machines. The average of three measurements was used for each combination. Systolic and diastolic blood pressure, and large-artery and small-artery elasticity indices, were determined for each subject and used in the analysis. RESULTS: The subjects were 11 males and 9 females between 22 and 46 (33.5 +/- 7.4 years) years of age. There was no significant difference in the average difference for each test combination. CONCLUSION: Thus, when using the HDI/Pulsewave CR-2000 Research CardioVascular Profiling System, the blood pressure cuff and the sensor can be placed on either the same arm or opposite arms.

Alavi et al. (2002) reported a cross-sectional. Cuff and sensor placed on the same arm vs. Cuff and sensor placed on opposite arms was evaluated on Average difference in systolic and diastolic blood pressure, and large-artery and small-artery elasticity indices. Placement of the blood pressure cuff and sensor on the same arm versus opposite arms resulted in no significant difference in measured blood pressure or arterial elasticity indices.
