Pulse oximeter

Abstract— Optical Pulse Oximetry is feasibly the greatest advance in patient monitoring. Pulse Oximetry enables oxygenation, an important physiological variable that is poorly detected by clinical means, to be monitored continuously and easily. Hypoxemia is commonly found in all aspects of medical practice and is a major cause of organ abnormality and death. It should be widely available and used routinely in clinical practice both in primary care and in hospital. This paper will design a non-invasive optical pulse oximeter using the Arduino. The pulse oximeter consists of a sensor and an Arduino microcontroller. The (Photo Transistor) sensor is used for the pulse wave 's detection, and the Arduino microcontroller is designed to analyze…

owned up to its mistake, listened to customer feedback, and went back to the drawing board. Acc U Rate’s decision to listen to its customers proved extremely beneficial as the newly designed CMS 500DL Pro Series has become incredibly popular. Unlike its predecessor, the CMS 500DL Pro Series offers consistently accurate readings, the kind you would expect from a wrist or upper-arm blood pressure monitor. It is designed to be used by hikers, runners, and anybody else who might need a reading…

Pulse oximetry is a noninvasive procedure that is used to measure the oxygen saturation level of the newborn (Pillitteri & Pillitteri, 2013). The device used in pulse oximetry readings contains two diodes that release equal concentrations of red and infrared light concurrently into the tissue bed the electrode is secured (WHO, 2011). The reading that is displayed is the proportion of reduced hemoglobin and oxygenated blood that is calculated and displayed indicating the oxygen concentration…

Peripheral Pulse Checks and Amplitude Absence or diminished leg pulses may suggest peripheral arterial disease of intermittent claudication. Absence suggests occlusion by thrombus, embolus, or dissection. If the pulse is hypokinetic or of low volume and amplitude, this could suggest shock or myocardial infarction indicative of low cardiac output such in the case of cardiomyopathy, stenosis, tamponade, or pericarditis. Hyperkinetic or bounding pulses are large-amplitude and strong pulses may be…

Exercise effects the human body in many fascinating ways; as it causes the body to adapt and alter to aid the body’s stimulation. Take when carrying out the Harvard step test practical. This test is where a person carries out a period of exercise for a certain length of time and then records their heart rate before and for so long after the period. This shows how fit and healthy the heart is by showing how long it takes for the heart to go back to a regular resting pulse rate. “The…

Introduction: The heart rate of an animal can be used as an indicator to identify when a stimulus evokes a reaction from the animal. Specifically in the case of humans’, there tends to be the cognitive ability to physically withhold a reaction from a stimulus and mask the involuntary reaction. However, the heart rate reacts immediately after a stimulus, and is not reigned in or controlled cognitively, so could the heart potentially be a true indicator of an individuals reaction to a stimulus?…

assessment because every morning when I got him up for the day, he would mention that he was tired and did not sleep well. After preforming this assessment, I was able to realized how poor and disturbed his sleep patterns were. He scored a 4 on this assessment, meaning that he is considered to be a poor sleeper. For him, the greatest perceived disturbance to his sleep is the amount of pain that he is in. By doing this sleep quality index the provider is able to see what is affecting the clients…

blood pressure is affected when the arm is positioned differently; blood pressure is highest when relaxed and fully extended and lowest when arm is held above subject’s head. Table 3 depicts the interval, or the amount of time, between two pulses. Table 4 depicts the calculate heart rates of volunteer 1 and 2 based upon the amplitude and interval of each pulse. As interval decreases, heart rate increase and amplitude does not affect rate, but represents the…

1 shows only a 0.5 difference in heartrate. This suggests that participants had a higher arousal level after listening to high energy music supporting the hypothesis. In both trials however, heart rate increase is minor, establishing a marginal effect on the relationship between music type and physical arousal. While the hypothesis is supported to an extent, this experiment lacks the reliability and the imperical evidence to support whether music preference relates to an increased physcial…

Does an Increase in Heart Rate affect the height of a Vertical Jump? Introduction: Whether it’s dunking, spiking or getting over that bar, every athlete strives to perfect a high jump. A vertical jump is the action of increasing the centre of gravity in the vertical plane with only the use of one's own muscles (Verma, C, (2015)). The motion of a vertical jump is used in many sports including volleyball, basketball and even football. In sports such as volleyball it could mean the difference…
