ABSTRACT:
Pulse oximetry has become a standard procedure for the measurement of blood-oxygen saturation in hospitals, clinics, etc. Pulse oximeter can directly detect hypoxemia, deficiency of oxygen saturation in the arterial blood. Early detection of hypoxemia can reduce the gas poisoning by CO2 or CO, tissue damage, etc. Thus, the oxygen saturation of the blood can quickly and accurately be monitored non-invasively using pulse oximeter. Pulse oximeter works on the principal of absorption and reflectance/transmittance of light by multiple components like skin, muscle and blood vessel. Absorption due to

They are sometimes called photovoltaic cells because they use sunlight ("photo" comes from the Greek word for light) to make electricity (the word "voltaic" is a reference to electricity pioneer Alessandro Volta).
Principle of Power Generation:
The principle of power generation behind the solar cells consists of the utilization of the photovoltaic effect of semiconductors. When such a cell is exposed to light, electron-hole pairs are generated in proportion to the intensity of the light. Solar cells are made by bonding together p-type and n-type semi- conductors.
The negatively charged electrons move to the n-type semi- conductor while the positively charged holes move to the p-type semiconductor. They collect at both electrodes to form a potential. When the two electrodes are connected by a wire, a current flows and the electric power thus generated can be transferred to an outside application.

Spirometry: A Career As A Medical Assistant
210 Words | 1 PagesUnderstanding respiratory volumes, capacities, and measurements will help me perform my job as a medical assistant because they are significant being a medical assistant. First of all, when the patient is on the bed, I will measure the respiratory rate while he/she is at relaxation. In the next, I will observe the rise and fall of the victim 's chest and count the number of respirations for one full minute. Then, I will record the current time, respiratory rate and respiratory characteristics. Spirometry is used diagnose conditions that affect breathing such as asthma, pulmonary fibrosis, and cystic fibrosis.
Acute Respiratory Distress Syndrome (ARDS)
2175 Words | 9 PagesComputerized tomography (CT) scan combines X-ray images taken from many different directions into cross-sectional views of internal organs. CT scans can provide detailed information about the structures within the heart and lungs. 4.3.2 Lab tests. A test using blood from an artery in your wrist can measure oxygen level.
Cardiopulmonary System
486 Words | 2 PagesIn this experiment, we will focus on how exercise, in particular, affects the cardiopulmonary physiology of boys across different body mass indexes. Exercise places strenuous activity on the human body. When an individual exercise, the blood flow must level up to the demands being made on the individual’s muscles, heart, and lungs. Blood flow increases so that the blood does not clot
Soldier's Heart Comparison Essay
479 Words | 2 PagesComparing and Contrasting the Books The Red Badge of Courage and Soldier’s Heart Soldier’s Heart and The Red Badge of Courage has so many similarities and differences they just keep piling up. There are more similarities than differences in the two books. It will be hard to find a lot of differences in the two books. When reading the two novels and comparing and contrasting irony there are more similarities than differences.
Polygraph Description
686 Words | 3 PagesThis in turn records the subject 's breathing rate, making it easy to see where faster, more nervous breathing has occurred. Blood pressure cuff and bellows A blood pressure cuff is placed around a subject 's upper arm. The tubing from the cuff is connected to the polygraph, and as the blood pumps in the subject 's arm a sound is made. The changes in pressure cause by the sound displaces the air in the tubes and causes another bellows mechanism to react, which again moves another pen on the machine.
Soldier's Heart Analysis
613 Words | 3 PagesSoldier’s Heart is written by Gary Paulsen and is based on a true story. The story Soldier’s Heart is about a boy named Charley Goddard who wants to become a man. Charley does have soldier's heart. Soldier’s heart is a disease name that was used during the times of Civil War. it was said that although the disease was called soldier’s heart, most people did not know what the disease was.
Gatorade Battery Report
693 Words | 3 PagesDid you know that Gatorade and other sports drinks contain electrolytes that can be used in a battery solution? These electrolytes are the same ones that replenish your body after exercise. Gatorade and other drinks have different electrolyte activity rates. That makes the battery either more or less powerful. A battery can be made with more electrolyte containing materials than you think.
Bradycardia Experiment
228 Words | 1 PagesA lot of people love sugary foods and drinks. This experiment can be applied to the real world because it shows how something so delicious can affect our overall health exceedingly. Since sugar affects our heart rate and blood pressure in different ways in many peculiar people, there are contrasting affects that can happen to people. For example, sugar can make the human body 's pulse and blood pressure increase or decrease. Both ways can be risky for your health.
Cardiovascular Response Essay
1583 Words | 7 PagesAt the dynamic exercise onset, oxygen consumption starts to increase, continues to rise through the initial time of sustained exercise, but then flattens as transport and uptake are increased adequately so that the consumption is matched to the demand (Laughlin S245). In the recovery stage, oxygen uptake will eventually surpass oxygen supply to a point at which oxygen consumption rate exceeds aerobic capacity resulting in oxygen
Vo2 Max Lab Report
296 Words | 2 PagesThe maximal test measures the volume of air that is expired by an individual. This expired air is then analyzed to determine the oxygen and carbon dioxide content is done using either a Douglas bags or the metabolic cart. Whereas the submaximal test is create to ensure the intensity does not exceed 85% of the individual’s maximal heart rate. The physiological rationale for the submaximal testing is that heart rate and work rate have a linear relationship. The submaximal test, provides an estimate of an individual’s VO2max not the actual VO2max.
Summary: A Case Study
1810 Words | 8 Pages2) Arterial Doppler: Arterial Doppler on both lower limbs was done to all subjects in the study. How was it prepared: We asked participants to rest and stop using products that contain nicotine (cigarettes, chewing tobacco) for 30 minutes to 2 hours before the test. Nicotine causes blood vessels to constrict and may give false results.
Nitric Oxide Lab
731 Words | 3 PagesQuestion. How can nitric oxide production from perfused organs be determined? Problem. It is thought that Nitric Oxide is important in signalling between neurons as well as in the vascular endothelium. NO plays a key role as the endothelium-derived relaxing factor (EDRF), which regulates vascular constriction and relaxation and is thus highly correlated with perfused organs (1).
Respirometer Experiment
1436 Words | 6 PagesThis will be done using a respirometer which will measure the rate of oxygen usage. The change in volume recorded by the respirometer pipette will be an indication of this. BACKGROUND INFORMATION
Blood Pressure Paper
962 Words | 4 PagesIn the study, diastolic and systolic blood pressure remained relatively constant when healthy food such as green salad (containing lettuce, tomato, cucumber and feta cheese), mixed vegetables (containing carrots, beans, baby marrow and gem squash) and a fruit salad (containing oranges, melons, grapes, strawberries and apple) – were consumed. When unhealthy food such as a cheeseburger, oily fried chips and doughnuts were consumed, the diastolic and systolic blood pressure increased slightly and then dropped. In figure two and three, one can conclude that unhealthy food in small amounts affects blood pressure slightly by increasing it. In a study conducted in Iran, unhealthy food such a sweets and fast food were the causes of increased blood
