Oxygen mask

I could picture the Earth in my head. The blues of water, greens of vegetation, and whites of clouds, all the essentials of life swirling together as if left by brush strokes. I had been seeing it since my first earth science class in elementary school, glaring out at me from textbooks as if demanding an answer. How could you do this? The question reverberated in my head, the dull ache of cognitive dissonance setting in as I peered out the window. I didn’t have an answer. None of us did. That’s…

CHAPTER I INTRODUCTION 1.1 BACKGROUND STUDY Wastewater in the textile , plastic, paper and cosmetics industry is a major threat to the environment. The volume of wastewater produced starts from different processes throughout from the pretreatments to the final treatment. The contents found in the wastewater are complex, having inorganic and organic compound chemicals in it and aquatic lives are at risk. Some of these wastes have even caused mutation in genetic coding of the marine…

Evaluation of the physiologic effects of high-flow nasal cannula (HFNC), which “is a heated, humidified, high-flow oxygen delivery system that can generate total gas flows of up to 60 L/min with an adjustable FIO2”, compared to conventional oxygen therapy (COT) for patients with hypoxemia and acute dyspnea in the emergency department was the focus of this study published in the American Association for Respiratory Care Journal (Rittayami, Tscheikuna, Praphruetkit, & Kijpinyochai, 2015). The…

Oxygen is one of the most common used drug in emergency medicine and when it is used judiciously in the treatment of hypoxemia it undoubtedly saves life. However, oxygen is often used inappropriately and the dangers of over-oxygenation are unappreciated. Routine oxygen administration is a medical intervention that can be for a variety of purposes in both chronic and acute patients. A normal air rate is composed of 20.95% oxygen by volume and it is essential for cell metabolism in return tissue…

Instead of an oxygen flow rate of 1-6LPM, flow rates of 25-70LPM are used instead for patients in acute respiratory failure (not breathing). HFNC is currently used in a variety of ways. In patients requiring intubation, traditional oxygen sources must be removed while the physician attempts the procedure. This is sometimes time consuming, allowing the patient’s blood oxygen levels to rapidly fall below the acceptable 93% threshold in less than…

oxygenation should be considered in standard practice. In research conducted by Miguel-Montanes and colleagues (2015) and Sakles and colleagues (2016), use of apneic oxygenation was found to decrease the incidence of oxygen desaturation during intubation when compared to a non-rebreather mask for pre-oxygenation alone. These were both single-center observational studies conducted at teaching hospitals. Despite the study designs, diversity of the patient populations studied, and the different…

gases from polluting the air we breath. The trees use “GreenHouse” to restore the balance in the atmosphere We should be trying to stop deforestation so it would not disappear completely. Without trees our oxygen will reduce we will have less oxygen because trees are the ones that produce our oxygen so we can breath and our air would be polluted even more with all the car and factories that we use all around the world brings many gases that have chemicals in it that pollute our air.…

Colorado gets about 15.9 inches of rainfall per year. Rain used to be one of the best things that could happen in this state, but as humans pollute our world more and more, rain is becoming harmful. Our precious rainfall is becoming more and more acidic, which is causing harm to plants, wildlife, buildings, and humans. This acidic rain is commonly referred to as acid rain and more properly known as acid deposition. This research will thoroughly examine acid rain, it’s causes, the effects on the…

Sodium polyacrylate is a polymer with a unique structure, that chemists are leveraging in a variety of lucrative industrial applications. Sodium polyacrylate possesses a unique chemical property: the ability to absorb incredible amounts of water. It can absorb 300 to 800 times its weight in water (Superabsorbent Polymers). Industrial chemists have taken advantage of the polymer’s special function, and have incorporated it into dozens of different products. In fact, the industry behind…

At the water molecule occurs the covalent bond. Hydrogen has an inferior electronegativity compared with oxygen.4 Oxygen attracted the negatively charged electrons, and it makes the oxygen has a negative charge. 4 The opposite applies to hydrogen, and makes it has a positive…
