As a smartphone is becoming very popular and its performance is being improved fast, a smartphone shows its potential as a low-cost physiological measurement solution which is accurate and can be used beyond the clinical environment. Because cardiac pulse leads the subtle color change of a skin, a pulsatile signal which can be described as photoplethysmographic PPG signal can be measured through recording facial video using a digital camera. In this paper, we explore the potential that the reliable heart rate can be measured remotely by the facial video recorded using smartphone camera. First, using the front facing-camera of a smartphone, facial video was recorded. We detected facial region on the image of each frame using face detection, and yielded the raw trace signal from the green channel of the image.
The Effects Of Caffeine On The Heart Rate Variability - Words
This paper explores and explains the findings of the heart rate experiment conducted by the students of Grand Canyon University for the Anatomy and Physiology Laboratory course. Over a two week time span, students were asked to record their heart rate, before, during, and after activities as instructed by the professor. Specifically, this paper focuses on the female students, comparing the heart rates of individuals who reported that they drink coffee versus those females who reported that they. Is caffeine good or bad? This research will test if caffeine is good or bad for humans.
Simulation is regarded as an effective educational method for the delivery of clinical scenarios. Students were interviewed about stress experienced during the simulation. The results showed that HF decreased significantly from the break to the patient care and reporting phases.
