Pulse-width modulation

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?…

sleep, and is therefore able to alter care in order to make sure the client has enough sleep to feel well-rested and heal properly. Physical Assessment Dates of assessments: May 18, 19 and 20th. Vital Signs: Temp –36.9 degrees C. O2 – 94. Pulse – 102 bpm. Apical pulse – 88 bpm. BP left ar0m – 112/ 84. Weight: 143.3 lbs Respirations – 14 breaths/min. Pain: 6.…

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…

arousal. Physical arousal levels were measured by calculating the rate at which ones heart beats before and after exposure to the two music genres. While the measure of heartrate itself is objective quantitative data, participants measured their own pulse and recorded the beats per minuete through the wrist or neck. Although we assume the measurement is correct, this method may have caused error within the investigation, as the is lacks the precision of for example, a heart rate monitor.…

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…

developing cardiovascular disorders (“Physical Activity”). The number of beats per minute equals heart rate (765). To find heart rate, a pulse point must be determined on the body, and the most common are the carotid and radial arteries (795). The rhythmic throbbing of the arterial wall as blood is being pumped is called a pulse (795). By knowing this information about a pulse, we can correctly identify the number of beats per minute. Each heartbeat is different from the next one (Watanabe).…

following four min after the exercise. In contrast, three out of the five males recovered although they had a much lower rate change in comparison to the females. This data is illustrated in graphs four, five, and six. Pulse rate The females tested on average had a significantly greater pulse rate at rest and immediately after the exercise in comparison to the males. Although the net change between male and females was very close, the recovery was not. All of the male pule rates recovered…

her emotional state depicts as uncooperative and groggy, but as the morning progressed, she became more awake and alert. Her 0800 vital signs are as follows: oral temperature 98.3 degrees Fahrenheit, respiratory rate 16, heart rate via left radial pulse is 46, blood pressure 170/66 left arm lying down, oxygen saturation is 97% using her left digital probe finger and is on room air. The patient denies any pain, and I was told to monitor the patient periodically throughout my shift by the HCP. The…

after exercising. Some of the control variables were the amount of time that subjects exercised (15 minutes), the age of the subjects that were tested (10-11 years old), and the timer used to keep track of how long the participant exercised and record pulse. The control group in this project was the group of subjects that walked. The experimental groups were the group of participants that ran, jump roped, and did jumping jacks. The procedures were…

Report Summary: Gas Exchange Methods of analysis: Andrea used a heart rate monitor to record and compare the impact the spin class has – before, during and after- on her heart. The heart rate monitor consist of two parts they work together. The transmitter which looks like a belt and needs to be fixed around the chest and the receiver will be worn as a watch on the wrist. They have different functions, the monitor will measure and record your average heart rate from the moment the monitor is…
