1. PHOTOPLETHYSMOGRAPHY Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissue (1). Pulse Photoplethysmography was introduced to the world by Hertzman in the year 1938. It is a noninvasive technique that makes use of light source and a detector. The change in blood volume is synchronous to heart beat and hence this method can indirectly measure heart rate. PPG has been used to assess skin

foods high in saturated fat that can raise your cholesterol should be avoided. Hypertension is another risk factor that can be controlled and overcome. Hypertension is when the heart contracts and the pressure is high enough in the arteries and veins that there is risk of rupture on an aneurism. Usually if this is the case the heart is working too hard and needs to be controlled with diet or medication. In most cases a low sodium diet or medications that contain a Beta blocker can be introduced

decrease respectively. Normally a person perspires to cool off. This causes him to lose fluid and become dehydrated. As a result‚ the body has to come up with another way to cool off‚ so the blood vessels dilate. This lowers the pressure within the veins‚ allowing the blood to cool. Caffeine is a stimulant and causes increased HR‚ and when a person exercises‚ their heart rate increases. All of this is to meet the body’s metabolic needs‚ producing adequate perfusion. Heart rate is brought back to homeostasis
