Oxygen

Understanding oxygen supply and demand while working in the health care field is essential. The tissue cell mitochondria need to have adequate oxygen for metabolic consumption and ATP production. There are limited means of oxygen storage in the tissues; as such a continuous supply of oxygen is required. The respiratory and cardiovascular systems work together to make sure oxygen is delivered throughout the body, and that these continuous requirements are met. Exploring the main role of the respiratory system in this process and its relationship with the cardiovascular system is best explained in 4 main steps. 1. “Uptake in the lungs 2. Carrying capacity of blood 3. Global delivery from lungs to tissue 4. Cellular use of oxygen” (Treacher &…

Scalpel. Doctor, patient’s O2 sat. is 70 percent and dropping fast! Place an oxygen mask on her. Kelly. I need a size [insert] chest tube. Doctor, her oxygen saturation is coming back up slowly. Good, keep watching it. Tube is in; get X-ray in here to check for placement. The patient’s oxygen saturation is now in the high 90s. Alright, lower her oxygen level and see how she does. All vitals look good, patient is doing well at two liters of oxygen, and placement is good. I am going to go and talk…

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…

CaSO4 CaSO4 has the largest oxygen carrying capacity among all the currently proposed carriers. The oxygen ratio is 0.4706 for CaSO4-calcium sulphide (CaS), much higher than that of many other metal oxides such as CuO-Cu2O, NiO-Ni, and Fe2O3- Fe3O4. Calcium sulphate is a relatively stable material. It is a widespread natural resource and therefore the cost would be quite low even if the demand is high. Through the thermodynamic analysis, it seemed that CaSO4 can be used as a promising oxygen…

colorless, transparent and odorless liquid that exists in all three states of matter. It plays three major roles as the: a) universal solvent, b) reactant molecule, and d) temperature stabilizer. Water is created when Hydrogen and Oxygen undergoes synthesis reaction as 2H2 + O2  2H¬2¬O. In the process, an oxygen atom is covalently bonded to the two hydrogen atoms forming a non-linear molecular shape of water. According to the Valence shell electron pair repulsion (VSEPR) theory, the two lone…

know that at the Eustache Institute we specialize in neurofeedback therapy. However, an additional treatment we proudly provide is Hyperbaric Oxygen Therapy (HBOT), which involves breathing pure oxygen in a pressurized chamber, allowing our lungs to gather more oxygen than would be possible breathing pure oxygen at normal air pressure. Our blood will then carry the oxygen throughout our body and our organs, helping to fight bacteria while stimulating the release of substances called growth…

Joseph Priestley was a famous chemist. He was famous for inventing soda water, his writings about electricity, and his discovery of gases. Joseph was born on March 24, 1733, in Bristall. He died February 6, 1804 at the age of 70. Joseph is most known for his discovery of oxygen and for isolating it. Oxygen was not first discovered by Joseph, instead the famous Swedish chemist, Carl W. Scheele, in 1772. Joseph discovered Oxygen independently in 1774. Joseph published his findings in the…

Oxygen can be delivered by low or high flow systems depending upon the client’s need. Low flow methods allow for room air to be inhaled along with the supplemental oxygen; examples of low flow methods include nasal cannulas, face masks, oxygen tents, and transtracheal catheters. The nasal cannula can deliver 2 to 6 L/minute and is the cheapest most commonly utilized device tolerated well by clients. In addition, the device is easily applied and does not block the mouth allowing the client the…

Mary Oliver wrote the poem “oxygen”, which was released in her collection as one of the forty-three poems written in her book Thirst. Written during a time she was going through the loss of a loved one, Mary writes “Oxygen” to express her gratitude toward her relationship. The poem is short and simple, yet is deep as it uses the idea of oxygen to represent love and life. “Oxygen” is written about two people, one of whom is ill and living on a breathing machine. The other person is explaining…
