Tiivistelmä
The purpose of the study was to determine the reliability of a blood pressure sensor developed by Murata as a blood pressure monitoring tool compared to an automatic blood pressure monitor, Omron M6.
Blood pressure is one of the principal vital signs and is utilized for monitoring both short-term and long-term health of the cardiovascular system and thereby the health of the patient. Therefore there is a need for a non-invasive blood pressure monitor for accurate, continuous and comfortable measuring in both hospital and home environments.
The sample in this study was 80 adult patients, including both females and males. The aim was to measure their blood pressure first with the sensor by collecting one minute of the measurement data and then with the reference monitor. All measurements were taken in the same order from the right hand.
There was a difference between the sensor and the reference measurement. In diastolic blood pressure the difference was minor, whereas in systolic blood pressure the difference was more significant. The difference between females (62 patients) and males (18 patients) was discernible. The influence of BMI turned out to be insignificant, but age and blood pressure medication might have some influence.
The sensor was very sensitive for distraction and the wristbands challenging to use. For future the sensor should be more tolerant, easier to position and should collect the data in order to work without a computer.
