Key result
An automated sphygmomanometer based on an oscillometric method yielded an accurate measurement rate of 95.0% at rest, but accuracy fell to between 0.0% and 65.0% during various forms of exercise.

Does an automated sphygmomanometer based on an oscillometric method accurately measure blood pressure during exercise in healthy subjects?
Automated sphygmomanometers based on oscillometric methods are reliable for blood pressure measurement at rest but highly inaccurate during exercise.
Oscillometric automated BP monitors appear unreliable during exercise; small healthy cohort leaves validation in patients open.
[Purpose] This study investigated the reliability of an automated sphygmomanometer based on an oscillometric method, when used during exercise. [Subjects and Methods] Ten healthy subjects were included. Blood pressure (BP) was measured with an automated sphygmomanometer based on a cuff-oscillometric method. The experiment consisted of five tests: sitting posture at rest, walking with swinging the upper limbs, walking without swinging the upper limbs, walking on a treadmill, and riding a bicycle ergometer. Right and left brachial artery BP was measured twice at the same times. If the difference in systolic BP on bilateral testing was less than 15 mmHg, it was judged to be accurate, and accurate measurement rates were calculated. [Results] BP could not be measured in most limbs on walking with swinging the upper limbs, walking without swinging the upper limbs, or walking on a treadmill. The accurate measurement rates in bilateral limbs were 95.0% in sitting posture at rest, 0.0% on walking with swinging upper limbs, 5.0% on walking without swinging upper limbs, 15.0% on walking on a treadmill, and 65.0% on riding a bicycle ergometer. [Conclusion] An automated sphygmomanometer based on an oscillometric method was useful for BP measurement only at rest.

Shinohara et al. (2017) conducted a cross-sectional in Healthy (n=10). Automated sphygmomanometer based on an oscillometric method during exercise vs. Measurement at rest was evaluated on Accurate measurement rate (difference in systolic BP on bilateral testing < 15 mmHg). An automated sphygmomanometer based on an oscillometric method yielded an accurate measurement rate of 95.0% at rest, but accuracy fell to between 0.0% and 65.0% during various forms of exercise.
