Objective: Central systolic blood pressure (cSBP) is usually estimated by application of a transfer function (TF) to a peripheral arterial waveform. These waveforms are usually calibrated by using either mean (MAP) and diastolic (DBP) blood pressure or systolic blood pressure (SBP) and DBP obtained from an arm cuff. The aim of the present study was to determine whether cSBP derived from upper arm cuff pressure is as accurate as that obtained from radial tonometry.
Methods: We compared estimates of cSBP obtained by application of a TF to arm cuff pressure waveforms with those obtained using a SphygmoCor device (Atcor Medical, Australia) on 42 subjects (20 women, aged 48 ± 17 years). Waveforms were calibrated using oscillometric values of MAP and DBP and SBP and DBP.
Results: Irrespective of the calibration, there was a close agreement between estimated values from the arm cuff waveforms and radial tonometry: mean difference (SD) −0.46 (4.15) mmHg for MAP and DBP calibration and 2.16 (4.38) mmHg for SBP and DBP calibration.
Conclusion: These results suggest that cSBP can potentially be determined directly from an upper arm blood pressure cuff with similar accuracy to that obtained using the current methods.
