[ 1 ] - ارزیابی خون رسانی به بافت در ناحیه عضلات ذوزنقه با تحلیل موجک سیگنال حجم سنجی نوری به کمک شبکه عصبی
Measurement of tissue blood perfusion has many applications in the prevention of pressure sores, muscle activity assessment and care of tissue blood perfusion during surgery. Photoplethysmography as a continuous measure for evaluation of blood perfusion in tissue is accepted by researchers. In this study a new method for assessment of blood perfusion to the tissue based on photoplethysmograph s...
[ 2 ] - Increasing the Accuracy of Blood Hematocrit Measurement by Triplicate Wavelength Photoplethysmography Method
Background and objectives: The importance of continuous monitoring and rapid and accurate informing of changes in blood components (e.g., percentage of hematocrit [HCT]), especially in acute conditions, has motivated researchers to use non-invasive measurement methods. Therefore, this study aimed to evaluate the association between blood HCT and photoplethysmographic signal and the possibility ...
[ 3 ] - Assessment of Photoplethysmography Method in Extraction of Hemoglobin Concentration
Background: The importance of continuous monitoring along with rapid and accurate notification of changes in blood components such as hemoglobin concentration, especially in acute situations, encourages researchers to use non-invasive methods for measuring.Objective: This study was aimed to investigate the correlation between hemoglobin concentration and photoplethysmogram (PPG) and the p...
[ 4 ] - Quantification the Effect of Ageing on Characteristics of the Photoplethysmogram Using an Optimized Windkessel Model
Background: With increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. The changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. These changes clearly appear in specification of photoplethysmogram particularly in the size and...
