Our secondary objective was to miniaturize the technology. The standards used for most BP devices are maintained by the US Association for the Advancement of Medical Instrumentation (AAMI), the European Society of Hypertension Working Group on Blood Pressure Monitoring (ESH), British Hypertension Society (BHS) and the International Organization for Standardization (ISO). This involves comparing it to manual auscultation, the gold standard method for non-invasive monitoring of BP. In this study, our main objective was to validate the proposed device according to the international BP standards. We have also proposed a miniaturized version of the device in another study. Operation of the device was validated (n=33) against an automated arm cuff device (Omron M3) resulting in systolic (SBP) and diastolic (DBP) pressures (( mean ± SD) mmHg) of (−0.9 ± 7.3) mmHg and (−3.3 ± 6.6) mmHg, respectively. In our previous study we presented a tabletop tonometric instrument for measuring blood pressure from the fingertip. Similar techniques have been introduced before, but they require a bulky external pneumatic unit for pressure generation, or are based on user actuation. Our device relies on the oscillometric method to acquire spot BP measurements and it does not require any calibration. Moreover, these methods typically lack clinical validation and special situations and populations are seldom considered. These devices often require initial arm cuff calibration using a brachial cuff device. Most wearable BP measurement devices use pulse wave propagation or pulse wave analysis methods to measure BP. Current hypertension guidelines also recommend that blood pressure is measured regularly and frequently (instead of random spot measurement), despite traditional BP devices with an inflatable arm cuff being uncomfortable, especially in long-term use. Currently, the trend in BP monitoring devices is going towards wearable technologies and ease-of-use. With changing global lifestyle, hypertension is affecting everyounger individuals and its prevalence is increasing. Uncontrolled high blood pressure (BP) can lead to disability, poor quality of life, and fatal heart attack or stroke. Untreated hypertension is the greatest single contributor for cardiovascular disease and sudden cardiac death.
