The Difference

We studied a wearable blood pressure sensor using a fiber Bragg grating (FBG) sensor, which is a highly accurate strain sensor. This sensor is installed at the pulsation point of the human body to measure the pulse wave signal. A calibration curve is built that calculates the blood pressure by multivariate analysis using the pulse wave signal and a reference blood pressure measurement. However, if the measurement height of the FBG sensor is different from the reference measurement height, an error is included in the reference blood pressure. We verified the accuracy of the blood pressure calculation with respect to the measurement height difference and the posture of the subject. As the difference between the measurement height of the FBG sensor and the reference blood pressure measurement increased, the accuracy of the blood pressure calculation decreased. When the measurement height was identical and only posture was changed, good accuracy was achieved. In addition, when calibration curves were built using data measured in multiple postures, the blood pressure of each posture could be calculated from a single calibration curve. This will allow miniaturization of the necessary electronics of the sensor system, which is important for a wearable sensor.

The aim of the study was to determine the effectiveness of giving hydrotherapi foot soak in hypertensive patients. The study was conducted with one group pretestposttest design without a control group by measuring blood pressure (pretest) before being given an intervention in the form of foot soak hydrotherm against 15 people with hypertension in Banjar Sri Mandala, Dauhwaru Village, Jembrana Subregency. Then do the blood pressure measurement again (posttest) after finishing the intervention. After the study was completed, the results showed that before the hydrotherapi foot bath intervention, there were 0% of patients classified as normal, 13.32% in prehypertension category, 60.08% in hypertension category I and 26.60% in hypertension category II. After the intervention was given, there were 13.32% of the patients classified as normal, 66.68% in the prehypertension category, 20.00% in the first category of hypertension and no patients belonging to the second grade hypertension category. There is a decrease of 20-30 mmHg for systolic blood pressure and 0-10 mmHg for diastolic blood pressure after intervention. Based on the results of the study it can be concluded that the hydrotherapi foot bath is effectively used to reduce blood pressure in hypertensive patients in the Banjar Sri Mandala, Dauhwaru Village, Jembrana District.

Measure Blood Pressure

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).

BACKGROUND In the conventional method, the blood pressure values of pregnant women were measured by nurses in the obstetrics outpatient clinics, and then were entered into the computer system.The pregnant women should wait for long time to complete this process.We hypothesized that the self-service blood pressure measurement by pregnant women could be a better option rather than measuring the blood pressure by nurses. OBJECTIVE This study aimed to analyze the effect of self-service blood pressure measurement in obstetrical outpatient clinic on waiting time, satisfaction of pregnant women and outpatient volume, and provide reference for the optimization of outpatient service processes. METHODS This was a cross-sectional study. The waiting time and satisfaction degree of pregnant women, as well as the outpatient volume in the Obstetrics Outpatient Clinic were compared on the use of self-service blood pressure measurement system with the conventional method. A total of 519 pregnant women in the obstetrics outpatient clinics of Guangzhou Women and Children’s Medical Center in China participated in the satisfaction survey. The sample means were compared with t-test. RESULTS Compared to wait a longer queue for blood pressure measured by nurses, after using the self-service blood pressure measurement system, the waiting time of pregnant women for blood pressure measurement was significantly reduced from (18.57±9.68) min to (2.39±1.96) min (P<0.001). In addition, the satisfaction degree of pregnant women was significantly increased (P<0.001), and the monthly outpatient volume was significantly increased (P=0.02,P<0.05). CONCLUSIONS This study showed that after implementation of self-service blood pressure measurement, the waiting time of the pregnant women for blood pressure measurement was decreased significantly, while the satisfactory degree and outpatient flow were increased significantly, improving the cost-effectiveness.Therefore, this method is worth to be popularized in clinical practices. Relevance to clinical practice: How to use medical intelligence in clinical practices, replace manual works by self-service devices to address the high outpatient flow, high work load of medical personnel, and improve the experience of patients in seeking medical services are the most concerned issues by both patients as well as hospital managers.This study demonstrated that the self-service blood pressure measurement as a promising strategy in clinical practices and provided reference for the optimization of outpatient service processes. CLINICALTRIAL This study was approved by the Ethics Committee of the Guangzhou Women and Children’s Medical Center (approval number:SFE-KL-46401; Supplementary file 4). All the pregnant women included in this study signed the informed consent form.
