Evaluation of a Novel Brachial Cuff-Based Oscillometric Method for Estimating Central Systolic Pressure in Hemodialysis Patients
Why the study?
Does the Mobil-O-Graph oscillometric device provide comparable estimates of central systolic pressure and arterial stiffness compared to the Sphygmocor tonometric device in hemodialysis patients?
Population
73 hemodialysis patients
Comparison
Measurement of aortic SBP, AIx, and PWV using a… vs Measurement using a standard tonometric device
Design
Cross-sectional, Measurements were made in a randomized order

Implication
May support Mobil-O-Graph for aSBP and AIx in hemodialysis; leaves open PWV accuracy versus tonometry.
Structured PICO

P
Population
73 hemodialysis patients
I
Intervention
Measurement of aortic SBP, AIx(75), and PWV using a novel brachial cuff-based ambulatory oscillometric device (Mobil-O-Graph)
C
Comparator
Measurement using a standard tonometric device (Sphygmocor)
O
Outcome
Agreement in aortic SBP, AIx(75), and PWV between the two devicessurrogate
The Mobil-O-Graph oscillometric device provides acceptable estimates of central systolic blood pressure and augmentation index, but slightly underestimates pulse wave velocity compared to tonometry in hemodialysis patients.
