The number of cardiac patients and aged individuals are at a rise all around the world. Taking care of such individuals is a major challenge these days. In many cases, these patients require special care and regular monitoring of vital signs like blood pressure (BP). Focusing a prevalent idea of wireless brain-computer interface (WBCI), an innovative research work is considered to meet essential routine monitoring of BP for cardiac patients and aged people without any reliance. The research framework involves the use of wireless electroencephalogram (EEG) headset to control wrist BP and arm BP monitors to determine accurate BP readings in the proposed system. An Android application "Smart Home Monitor" is developed that screens the information from the headset. The research framework is tested on ten individuals to examine the precision in BP readings from two different BP monitors. Results specify that both upper arm blood pressure readings i.e. Systolic BP readings (SBP = 119.6 ±5.1 mmHg) and Diastolic BP (DBP = 79.5 ±7.4 mmHg) were found to be better than the wrist BP readings (SBP = 128.2 ±11.7 mmHg and DBP = 83.6 ±10.3 mmHg). This examination assessed that the designed system empowers the framework to be reliable, remote and compact.

BACKGROUND Wearable devices can provide user-friendly, accurate, and continuous blood pressure (BP) monitoring to assess patients’ vital signs and achieve remote patient management. Remote BP monitoring can substantially improve BP control. The newest cuffless BP monitoring devices have emerged in patient care using photoplethysmography. OBJECTIVE The Senbiosys trial aims to compare BP measurements of a new device capturing a photoplethysmography signal on the finger versus invasive measurements performed in patients with an arterial catheter in the intensive care unit (ICU) or referred for a coronarography at the Hospital of Fribourg. METHODS The Senbiosys study is a single-center, single-arm, prospective trial. The study population consists of adult patients undergoing coronarography or patients in the ICU with an arterial catheter in place. This study will enroll 35 adult patients, including 25 patients addressed for a coronarography and 10 patients in the ICU. The primary outcome is the assessment of mean bias (95% CI) for systolic BP, diastolic BP, and mean BP between noninvasive and invasive BP measurements. Secondary outcomes include a reliability index (Qualification Index) for BP epochs and count of qualified epochs. RESULTS Patient recruitment started in June 2021. Results are expected to be published by December 2021. CONCLUSIONS The findings of the Senbiosys trial are expected to improve remote BP monitoring. The diagnosis and treatment of hypertension should benefit from these advancements.

Background: The biggest challenge in our technologically advanced society is the healthy being of aging individuals and differently-abled people in our society. The leading cause for significant injuries and early death in senior citizens and differently-abled people is due to falling off. The possibility to automatically detect falls has increased demand for such devices, and the high detection rate is achieved using the wearable sensors, this technology has a quite social and monetary impact on society. So even for the daily activity in the life of aged people, an automatically fall detecting system and vital signs examining system become a necessity. Objectives: This research work aims at helping aged people and every other necessary human by monitoring their vital signs and fall prediction. A fall detection VitaFALL (Vital Signs and Fall Monitoring) device, could analyze the measurement in all three orthogonal directions using a triple-axis accelerometer, and Vital Signs Parameters (Heartrate, Heartbeat, and Temperature monitoring) for the aged and differently-abled people. Methods: Comparison with Present Algorithms, there are various benefits regarding privacy, success rate, and design of devices upgraded using an implemented algorithm over the ubiquitous algorithm. Results: As concluded from the experimental outcomes, the accuracy achieved is up to 94%, ADXL335 is a 3-Axial Accelerometer Module that collects the accelerations of aged people from a VitaFALL device. A guardian can be notified by sending a text message via GSM and GPRS module so that aged can be helped. Conclusion: However, a delay in the time can be noticed while comparing the gradient and minimum value to predetermine the state of the older person. The experiment results show the adequacy of the proposed approach.

Blood pressure is one of the vital signs, and is the pressure of circulating blood on the walls of blood vessels. When the large arteries lose their natural elasticity and strength, and the smaller ones are narrowed, blood pressure rises and the pressure is exerted by blood on the walls of blood vessels. High blood pressure is dangerous and very harmful for the heart and blood vessels, and is a major cause of mortality in all nations. Many patients tend to use herbal products for controlling their blood pressure, as they are concerned of the side effects of the chemical drugs. There are huge amount of research work exploring the safety and efficacy of a single herb, or combined herbal products on lowering blood pressure, among which some have shown certain effects, and some are negative in results. Grape seed, Garlic, Saffron, Green and White Mulberry, Quince, and some other herbs have more scientific evidence in lowering blood pressure. In this study, we systematically reviewed the scientific literature of clinical trials and animal studies, in which the safety and effectiveness of herbs on lowering blood pressure were evaluated.

Vital signs are regularly monitored in hospitalized patients. In the intensive care unit (ICU), traditional non-invasive blood pressure monitoring and telemetry may not provide enough information to determine the etiology of hemodynamic instability or guide intervention. Arterial catheters remain the gold-standard for continuous blood pressure monitoring and are commonly used in ICU patients. Pulmonary artery catheters and central venous catheters are beneficial in select patient populations and provide more advanced and specific information about a patient’s hemodynamics. However, neither are benign and can increase risk of complications such as infection, arrhythmias, pneumothorax and vascular or valvular damage. In the past 10 years, the development of reliable non-invasive (NICOM), or minimally-invasive (MICOM), cardiac output monitoring devices has accelerated. The MICOM devices require an arterial catheter to obtain hemodynamic values, whereas NICOM devices do not require any arterial or venous access. These devices have emerged to be particularly useful in evaluating and managing patients with suspected mixed shock. As these devices become more prevalent, it is imperative that clinical pharmacists become familiar with interpreting this data as it may have a substantial impact on medication selection and optimization. This review will discuss the basics of NICOM and MICOM devices, limitations with these methods of monitoring, and clinical application for pharmacists.

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.

The continuous blood pressure measurement research is widely known for helpingthe development of ambulatory blood pressure monitoring where it measures blood pressureevery 15 to 30 minutes throughout the day. The cuff is a problem for the patient withAmbulatory Blood Pressure Monitor. It can make a person feel uncomfortable and must staystill when the cuff starts to inflate. It is limiting and disturbing their daily activity when thedevice is starting to measure the blood pressure. Blood pressure measurement without cuff isbeing proposed in this research, called cuff-less blood pressure measurement. It will be based onPhotoplethysmography (PPG) and Electrocardiography (ECG) signal analysis. ECG (Lead 1,Lead 2, and Lead 3) with PPG signal produced from index finger on the left hand are comparedand analyzed. Then the relation of PPG and ECG signal and the optimum location for daily usecan be obtained. The optimum location will be based on the electrode’s position that producedthe optimum ECG lead Signal to measure blood pressure. Based on the result, PPG and ECGsignal have a linear relation with Blood Pressure Measurement and Lead 1 is more stable inproducing the ECG signal. The equation from Lead 1 appeared as one of the optimum equationsfor measuring Systolic Blood Pressure (SBP) or Diastolic Blood Pressure (DBP).

Purpose. To study the dynamics of blood pressure (BP) indicators under the influence of exogenously administered melatonin (Melatonin-SZ, Severnaya Zvezda, Russia) with various manifestations of desynchronosis of circadian BP rhythms (arterial hypertension – AH, high normal blood pressure) to determine the scheme of their effective compensation. Material and methods. The study included 101 patients with desynchronosis of circadian rhythms of blood pressure – 52 patients with hypertension, constituting the first and second groups, and 49 individuals with high normal blood pressure, representing the third and fourth groups. Patients of the second and fourth groups received conservative therapy, patients of the first and third groups combined it with melatonin. All patients underwent measurements of office blood pressure, home monitoring of blood pressure (ABPM), electrocardiography, 24-hour blood pressure monitoring (ABPM). Results and discussion. In patients of the first and third groups, compared with the traditional treatment groups, by the end of the observation period, a significantly (p < 0.05) decrease in office systolic blood pressure (SBP) / diastolic blood pressure (DBP) was established: in the first group compared with the second – 1.11 / 1.13 times, in the third group compared to the fourth – 1.43 / 1.58 times; significantly more (p < 0.05) pronounced decrease in SBP / DBP during DMAD – by 1.08 / 1.17 and 1.58 / 1.62 times, respectively, Significantly (p < 0.05) more pronounced decrease in average daily, average daily and average nighttime SBP / DBP during ABPM – by 1.13 / 1.20, 1.11 / 1.20, 1.23 / 1.25 and 1.47 / 1.31, 1.42 / 1.19, 1.54 / 1.41 times, respectively; reliably (p < 0.05) more frequent registration of the dipper rhythm type SBP / DBP – 1.6 / 1.4 and 1.6 / 1.4 times, respectively. In addition, the dynamics of patients in the first and third groups showed a significant (p < 0.05) decrease in the mean daily and mean nighttime SBP / DBP variability (SBP in the first group by 27.3 and 41.3 %, respectively; DBP in the first group by 20.1 and 26.3 %, respectively; SBP in the third group by 13.5 and 25.2 %, respectively; DBP in the third group by 12.2 and 28.2 %, respectively). Conclusions. With various manifestations of desynchronosis of circadian rhythms of blood pressure (AH, high normal blood pressure), the prescription of melatonin (Melatonin-SZ, Severnaya Zvezda, Russia) at a dose of 3 mg per day 30–40 minutes before bedtime for a month against the background of non-drug therapy and antihypertensive drugs led to a significantly more effective decrease in blood pressure at its office measurement, DMAD, ABPM with an improvement in the circadian rhythm of blood pressure and normalization of blood pressure variability.
