New Photoplethysmographic Signal Analysis Algorithm for Arterial Stiffness Estimation
The ability to identify premature arterial stiffening is of considerable value in the prevention of cardiovascular diseases. The "ageing index" (AGI), which is calculated from the second derivative photoplethysmographic (SDPPG) waveform, has been used as one method for arterial stiffness estimation and the evaluation of cardiovascular ageing. In this study, the new SDPPG analysis algorithm is p...
متن کاملCuff-free Blood Pressure Estimation Using Signal Processing Techniques
Since blood pressure is a significant parameter to examine people’s physical attributes and it is useful to indicate cardiovascular diseases, the measurement/estimation of blood pressure has gained increasing attention. The continuous, cuff-less and non-invasive blood pressure estimation is required for the daily health monitoring. In recent years, studies have been focusing on the ways of bloo...
متن کاملPilot investigation of photoplethysmographic signals and blood oxygen saturation values during blood pressure cuff-induced hypoperfusion
Photoplethysmography (PPG) is a non-invasive electro-optical technique widely used in the monitoring of the pulsations associated with changes in blood volume in a peripheral vascular bed. The technique is based on the absorption properties of vascular tissue when it is transilluminated by light. Photoplethysmography is also used in the estimation of arterial blood oxygen saturation ðSpO2Þ by p...
متن کاملA time-frequency domain approach of heart rate estimation from photoplethysmographic (PPG) signal
ObjectiveHeart rate monitoring using wrist type Photoplethysmographic (PPG) signals is getting popularity because of construction simplicity and low cost of wearable devices. The task becomes very difficult due to the presence of various motion artifacts. The objective is to develop algorithms to reduce the effect of motion artifacts and thus obtain accurate heart rate estimation. MethodsPropos...
متن کاملValidation of a fully automatic photoplethysmographic device for toe blood pressure measurement.
OBJECTIVES This study was designed to assess the accuracy and reliability of a new, portable, fully automated photoplethysmography (PPG) device for toe blood pressure (TBP) measurement. DESIGN Within-subject comparison with conventional laser Doppler (LD) measurement. MATERIALS AND METHODS Four TBP measurements were performed on both lower limbs, alternatively with LD and PPG in 200 patient...
