“…The remaining light source will either reflect or transmitted through the arteries, and this light residue is detected by photodetector. A blood flow wave is generated, and BP is estimated from the waveform (Jeong, Ko, Hwang, & Yoon, 2006). This two method will be further discussed in the following sections.…”

Hypertension, the abnormal elevation of blood pressure, is one of the chronic disease that usually comes with no symptom and signal. As the systolic blood pressure (SBP) over 140 mm Hg or diastolic blood pressure (DBP) is over 90 mmHg, it is considered as hypertension. The purpose of this paper is to determine a method to early diagnose of hypertension by monitoring the SBP, DBP, and heart rate (HR) non-invasively. Although accurate measurement of BP and HR of a person can be obtained invasively, the measuring probe needs to place under patient’s skin and it would cause wound. Therefore, this paper review on methods to measure BP and HR non-invasively. External pressures are needed to induce to the artery in order to measure BP and HR by using auscultatory and oscillometric methods, hence, a pressure cuff is used for measuring BP. The pressure cuff will restrict the motion of patient and it is not suitable for continuous monitoring. Pulse transit time (PTT) and photoplethysmography (PPG) methods are introduced to measuring BP non-invasively without cuff. The limitation of PTT over PPG is PTT needs both PPG waveform and ECG waveform to estimate BP, and artificial phase lag is occurred which will affect the reliability of the measured result. Therefore, for long term monitoring hypertension, non-invasively, by using photoplephymosgraphy method is preferred since it enables continuous monitoring without cuff and it is only one waveform, which is PPG waveform, is needed to estimate the BP as well as HR.

“…Both sets used the same feature extraction process. The first sub-set was based on the pulses wave decomposition; decomposing PPG pulse into 5 lognormal pulse, see (1), as suggested in [21]. The main idea lies on the theory of reflected pulses in the arteries.…”

Photoplethysmography (PPG) provides a simple, convenient and noninvasive method to assess pulse oximetry. Several attempts have been made to use PPG also to estimate blood pressure and arterial stiffness. This paper attempts to assess obesity classes, age group, and hypertension classes using PPG measured from the finger. One set of features was derived from the normalized pulse width of PPG and the other from original PPG. The features were calculated based on the pulse decomposition analysis using five lognormal functions and the up-slope of the PPG pulse. Using kNN and SVM as classifiers, the results were validated using leave-oneout validation. Performances of both features sets have no significant difference, and the kNN outperformed the SVM. The best accuracies are 93%, 88%, and 92% for obesity (5 classes), age group (7 classes), and hypertension (4 classes) respectively. These three assessment targets have a strong relationship with arterial stiffness, therefore it also leads to a study about arterial stiffness using PPG. Width normalization to 1 second might affect some features points based on pulse decomposition analysis. This study also found that the up-slope analysis might give good indices when width normalization was employed. However, these findings still require more experiments to gain conclusions that are more comprehensive.

“…Diastolic blood pressure (DBP) is measured when the heart rests between beats, relieving the arteries off the pressure. PPG signal has long been associated in the determination of arterial blood pressure [17,18]. In our proposed system, the arterial blood pressure is by computed by extracting a certain temporal characteristic from the PPG signal, known as diastolic time (T2) [19].…”

Promising development in the light emitting diode (LED) technology has spurred the interest to adapt LED for both illumination and data transmission. This has fostered the growth of interest in visible light communication (VLC), with on-going research to utilize VLC in various applications. This paper presents a mobile-health monitoring system, where healthcare information such as biomedical signals and patient information are transmitted via the LED lighting. A small and portable receiver module is designed and developed to be attached to the mobile device, providing a seamless monitoring environment. Three different healthcare information including ECG, PPG signals and HL7 text information is transmitted simultaneously, using a single channel VLC. This allows for a more precise and accurate monitoring and diagnosis. The data packet size is carefully designed, to transmit information in a minimal packet error rate. A comprehensive monitoring application is designed and developed through the use of a tablet computer in our study. Monitoring and evaluation such as heart rate and arterial blood pressure measurement can be performed concurrently. Real-time monitoring is demonstrated through experiment, where non-hazardous transmission method can be implemented alongside a portable device for better and safer healthcare service.
