Blood pressure is considered an index to measure a person’s health or state. The IEEE published a standard for wearable cuffless blood pressure measuring devices, which was certified as IEEE1708 on 26 August 2014, and, according to this standard, the development of wearable devices based on blood pressure is expected in the future. Considering this, blood pressure should be detectable all the time and everywhere, and this can help improve health consciousness. In this review, we introduce the recent development of wearable blood pressure measuring devices and research trends, and present the future prospects for blood pressure measuring devices.

These days most of the Blood Pressure (BP) measuring devices are having inflatable cuff that is needed to be occluded on the patient's arm for measuring blood pressure. This technique is not suitable in cases where continuous measurement of BP is required. Therefore, this work is aimed at designing of non-invasive and continuously monitors the blood pressure by using Pulse Transit Time (PTT) technique. For taking out PTT both of the signals are extracted from the body of the patient with the help of bio sensors i.e. Electrocardiogram (ECG) sensor and Photoplethysmogram (PPG) sensor. PTT was measured by taking the peak to peak time difference of ECG signal and PPG signal and this PTT is indirectly correlated with blood pressure, based on which Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) is calculated.

BACKGROUND Background: Continuous hemodynamic monitoring is the standard of care for patients intraoperatively, but vital signs monitoring is performed only periodically on post-surgical wards, and patients are routinely discharged home with no surveillance. Wearable continuous monitoring biosensor technologies have the potential to transform postoperative care with early detection of impending clinical deterioration. OBJECTIVE Objective: Our aim was to validate the accuracy of the Cloud DX Vitaliti™ Continuous Vital Signs Monitor (CVSM) continuous non-invasive blood pressure measurements in post-surgical patients. Usability of the Vitaliti™ CVSM was also examined. METHODS Methods: Included patients were recovering from surgery in a cardiac intensive care unit. Validation procedures were according to AAMI - ISO 81060-2 2013 standards for Wearable, Cuffless Blood Pressure Measuring Devices. In static (seated in bed) and supine positons, three 30-second cNIBP measurements were taken for each patient with the Vitaliti™ CVSM and an invasive arterial catheter. The errors of these determinations were calculated. Participants were interviewed about device acceptability RESULTS Results: Data for 21 patients were included in the validation analysis. The overall mean and SD of the errors of determination for the static position were -0.784 mmHg (SD 4.594) for systolic blood pressure and 0.477 mmHg (SD 1.668) for diastolic blood pressure. Errors of determination were slightly higher for the supine position at 3.533 mmHg (SD 6.335) for systolic blood pressure and 3.050 mmHg (SD 3.619) for diastolic blood pressure. The majority rated the Vitaliti™ CVSM as comfortable. CONCLUSIONS Conclusion: The Vitaliti™ CVSM was compliant with AAMI-ISO 81060-2:2013 standards and well-received by patients.
