Good Morning People,!!
The first study is about the Photoplethysmography (PPG). PPG is the devices that can measured beat rate of a person. Heart rate is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). So then, i have to study things that out of my major, which is about medication. What i search, due to individuals having a constant blood volume, one of the physiological ways to deliver more oxygen to an organ is to increase heart rate to permit blood to pass by the organ more often. Normal resting heart rates range from 60-100 bpm. Bradycardia is defined as a resting heart rate below 60 bpm. However, hearts rates from 50 to 60 bpm are common among healthy people and do not necessarily require special attention. Tachycardia is defined as a resting heart rate above 100 bpm, though persistent rest rates between 80-100 bpm, mainly is they are present during sleep maybe signs of hyperthyroidism or anemia.
This is just enough for my basic about health and medication, before developing heart beat rate devices that can view by smartphone via wirelessly. Then, i have to search the types of PPG that suitable to make it as Graphical User Interface for monitoring data in smartphone. Which the output from the PPG is send via wirelessly.
Research have been made, i found that a DIY photoplethysmographic sensor for measuring heart rate is more easier and not using much budget. Therefor, future modification of the PPG is easy to be done since there are diagram which still can i study with my supervisor. For more information regarding the DIY PPG can be found here http://embedded-lab.com/blog/?p=5508... See you in the next blog... Thanks for reading my blog until the 3rd week.
