Oxygen saturation Essays

between exercise, heart rate, and oxygen saturation. The human body depends on the oxygen transport by hemoglobin. Healthy adults have a normal oxygen saturation level between 94-99%. (Timmings, 2014). This means that the majority of oxygen is bound to hemoglobin. On the other hand, adults with respiratory and cardiac problems tend to have lower oxygen saturation level. Therefore, Haymond (2006) stated that oxygen saturation- the percentage of hemoglobin bounded to oxygen- is a clear indicator of a person’s

JANE JACOBS- “PAPER ON USES OF SIDEWALKS: SAFETY” Jane Jacobs , that “little old lady in tennis shoes”, who shook the white collar planners of the American cities, had written the book “life and Death of Great American cities”, which was published in 1960. I started reading this essay “Uses of sidewalks: Safety” from that book when I was in my first year and I was so moved and it was so amazing to read about planning which was completely different. This essay really looks at how the crowded neighborhoods

Data Presentation: Graph 1: Color vs Mass The solutions in the colors red, orange, and blue had final weights greater than their initial weights. The potato cores gained mass. The yellow, green, and purple sucrose solutions had initial weights was greater than their final weights. The potato cores loss mass. Table 1: Color vs Percent Change Color Percent Change red 5.22 % orange 10.81 % yellow -5.20 % green -1.56 % blue 9.45 % purple -1.81 % water 9.67 % Percent Change in Mass = Final Mass – Initial

To conclude, in this experiment, we set out to find how the concentration of sucrose affects the cell of a potato. The results that I got from the entire class’s data and my group’s data both indicated one thing. They show that as the amount of sucrose concentration increases by g/ml, the change between the final and the initial mass decreased. The percentage change in mass for the first 3 concentrations were positive because of the concentration of solute in the raw potato. The mass increase in

Osmolarity Lab 01 Ryanna Leslie BIO LAB 112 1.12.2023 Abstract: Six different solutions of water with different sucrose concentrations are used in the experiment measured in units of molarity. The solutions range from no solute to a high concentration of solute. They are 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 molar sucrose. Potato pieces are cut into similar sizes, weighed, and then placed in one of six solutions. As soon as the potato pieces are removed from the solution, they are blotted

1. Larry, who has 20% hct and 95% oxygen saturation would benefit by a transfusion because his hct is low, but does not need supplemental oxygen. Curly who has 40% hct and 95% oxygen saturation would be helped by neither because both hct and oxygen saturation percentage is in the normal range. Moe who has 30% hct and 95% oxygen saturation would benefit from a transfusion because his hct is low; however, supplemental oxygen would not be of any assistance. 2. a. At 60 mm Hg, the data values in the

parameters, Dissolved Oxygen, Biochemical Oxygen Demand and Dissolved Phosphates. Three samples were taken from midstream for both BOD and Dissolved Phosphates, these samples were later taken back to the lab were they were later analyzed and results were recorded. Dissolved oxygen was recorded further down-stream, at several different locations. Three samples were taken in shade and another three were taken in areas of sunlight, where the results were then later recorded. Dissolved Oxygen levels indicated

surrounded by a network of capillaries. The walls of the alveoli consist of a single layer of epithelial cells. The adjacent capillary walls are also constructed from a single layer of endothelial cells. This allows the diffusion of the pulmonary gases – oxygen and carbon dioxide – to take place more easily than it could across wider cellular

intoxicated, feel euphoric and lose judgement frequently. Research is being continued as an attempt to extend the depth limit for diving. The deepest dive to date was in 1979 when divers from NEDU completed a 37-day 1,800 fsw dive. More advanced saturation diving techniques are being created in different programs of developmental research. These experiments required substantial surface support and extensive under water equipment. Around the 20th century, most navies began developing the military submarine

EXPERIMENTAL RATIONALE Hydrocarbons are organic molecules consisting of hydrogen and carbon only1 and can be classified as saturated or unsaturated. A saturated hydrocarbon has the maximum number of hydrogens that can be present, given the number of carbons in the compound, for example, acyclic alkanes. A hydrocarbon is unsaturated if a hydrogen can be added1. This is a result of a hydrogen in the molecule being replaced, for example, with a double or triple bond or ring structure. Three examples

Why is supplemental oxygen used? To understand why supplemental oxygen use is deemed necessary, it is important to have a fundamental understanding of the significance of oxygen during cellular respiration. This metabolic pathway occurs either anaerobically or aerobically. Though each process produces adenosine triphosphate, anaerobic respiration—not involving the use of oxygen—produces only two ATP, whereas, aerobic respiration—involving the conversion of glucose into pyruvate, which undergoes oxidative

in order to test the water quality of a nearby water source, otherwise known as Lake Ripple. Such tests included testing for bare soil, bank erosion, water odor, soil odor, water appearance, benthic macroinvertebrates, coliform bacteria, dissolved oxygen, BOD, nitrates, pH, phosphates, temperature, and turbidity. All of these tests would be used to determine the overall quality of the water of Lake Ripple. There were two testing sites used to determine more accurate results. Samples were taken

earth’s environment is mirrored by an increase in the amount of carbonic acid present in the oceans .The sea water absorbs carbon dioxide, the reaction occur and the pH of the sea water decreases the carbonate ion concentration in the water and the saturation states of the biologically important calcium carbonate minerals also reduces. These reactions are named as ocean acidification .The ocean is found associated with the carbon cycle where the ocean acts as sink .It stores a large concentration

supplementation are associated with increased remineralization due to the increase of sinking particulates (Watson, 2012). Increasing remineralization has the possibility to decrease oxygen levels in surface waters, resulting in significant ocean oxygen depletion (Watson, 2012). This depletion of nutrients and oxygen in the oceans could result in an overall decrease in biological productivity causing more harm to the oceanic environment then the benefits produced by decreased greenhouse

fraction of oxygen, 21%, and other gases in the atmosphere remain constant on increasing altitude the barometric pressure decreases exponentially as we ascend above sea level. At sea level the atmospheric pressure is 760mmHg resulting in an oxygen partial pressure(pO2) of 150mmHg (taking water vapour into consideration.) On ascent to an altitude of 4000m the atmospheric pressure is reduced to 475mmHg resulting in a pO2 of 103mmHg. Because of the fall in pO2 the driving of force of oxygen into the blood

The primary function of the respiratory system is gas exchange, which consists of movement of oxygen into the body and removal of carbon dioxide. To achieve this goal, respiration can be divided and four major functions. First of all, we have pulmonary ventilation, which means the inflow and outflow of air between the atmosphere and the lung alveoli; second, the diffusion of oxygen and carbon dioxide occurs between the alveoli and the blood; after this, these gases are transported in the blood and

impulses) and to provide ATP so that more MgATP filler can be formed. Stored glycogen is the immediate source of energy for muscle activity. The glycogen is broken down by glycolitic enzymes to pyruvic acid, which is in turn broken down in the presence of oxygen (supplied by the blood) to carbon dioxide (removed by the blood) and water. During this process ATP is made available to form MgATP. The result is muscle relaxation. When an animal is slaughtered, it is bled until it dies. When it stops breathing

Butanol or butyl alcohol can be demonstrated to work in the Internal Combustion (IC) engine designed for use with gasoline without modification. It can be produced from biomass (biobutanol) as well as fossil fuels (petro-butanol). Both biobutanol and petro-butanol have the same chemical properties. Butanol is less corrosive than ethanol and has higher energy content than ethanol, similar energy content in gasoline. In comparison to ethanol, butanol is less prone to water contamination. As a result

involuntary response to breathe in response to: exchange carbon dioxide and oxygen, deliver oxygen to tissues and to regulate acid-base concentrations in the bloodstream. The air travels into the nose, down the trachea, bronchi, bronchioles, alveolar sacs then to the pulmonary capillaries. Froom the pulmonary capillaries hemoglobin picks up the oxygen molecules and travels through the arteries in the body to deliver the oxygen while picking up carbon dioxide and delivering it to the lungs through the

ice begins to form, the hydrogen bonds between the molecules become longer lived. They eventually settle into a rigid, rather open framework, comprising a stack of tetrahedrons, in which each oxygen atom is hydrogen-bonded to four surrounding oxygen atoms. The more open, rigid framework of ice fixes the oxygen atoms further apart than they tend to be, on average, in liquid water – which explains why ice is less dense than water.
