No doubt every person wants to be healthy in order to move well. One of the health conditions to note is to keep blood pressure. many people sick one cause is high blood pressure. there are two methods of measuring blood pressure ie invasive and non-invasive. using the oscillometric method the measurement can be performed automatically, with the help of a piezoresistive pressure sensor connected to arduino mega 2560. so that the measurement data in the form of name, age, and blood pressure can be stored on the SD card that can be read again if needed. In this research the difference between the systolic or diastolic values of blood pressure reading with analog devices compared with automatic blood pressure reading tool and obtained that the average difference of 3,265 mmHg for systolic value and 6,165 mmHg for diastolic. Then this difference is used in the calibration process so that the result of automatic blood pressure reading tool is better. The result of calibration reading tool has 99.47% - 99.82% accuracy

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).

Caffeine has been shown to increase mean blood pressure, but studies documenting the effect of caffeine on digits are lacking. We evaluated the effect of caffeine on digital blood pressure and pulse volume in normal volunteers. In the first part of the study, 24 subjects were given water containing either 200 mg of caffeine or placebo. Bilateral brachial and middle finger digital pressures were measured at room temperature before ingestion and at 30 and 60 minutes after ingestion. In the second part of the study, pulse volume recordings (PVRs) were obtained in 24 subjects at the level of the distal phalanx of the middle finger of one hand immediately prior to beverage ingestion and at 10 minute intervals for 90 minutes. Differences in mean digital systolic pressure, digital/brachial index, or PVR amplitude between the control and caffeine groups were not statistically significant. The administration of caffeine was found not to alter the haemodynamics of digital blood flow or digital pressure in this population.

This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14–19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test). Simple and multiple linear regression analyses revealed that aerobic fitness and muscle strength/resistance best explained variations in systolic blood pressure for boys (17.3% and 7.4% of variance) and girls (7.4% of variance). Aerobic fitness, body composition, and muscle strength/resistance are all important indicators of blood pressure control, but aerobic fitness was a stronger predictor of systolic blood pressure in boys and of diastolic blood pressure in both sexes.
