injury due to failure of pressure equalization of an air-filled space with its surrounding environment (Bentz‚ B. G.‚ & Hughes‚ C. A). Barotrauma most often occurs in air travel and scuba diving. Barotrauma may also be the result of hyperbaric oxygen therapy‚ an oxygen treatment used for patients with serious infections or wounds (Heyboer‚ 2014). Barotrauma can affect any air-filled space within the body such as the ears‚ face and lungs. In this paper‚ I will focus on barotrauma as it relates to

Gladys Martin July 2005 Indications for Blood Transfusions Goal of transfusing: Preserve oxygen delivery to tissues and avoid myocardial ischemia. One can do this by increasing the oxygen-carrying capacity of blood by raising the Hgb concentration of patients with acute/chronic anemia. Each unit will raise the Hct by 3 to 4 percent unless there is continued bleeding. Background: Transfusion trigger based on the 10/30 rule‚ give 2 units. However‚ with the discovery of transfusion-related HIV and

formation is a reversible process‚ the half-time of CO elimination from blood is consider long: ranging from 2-6.5 hours (Gardner‚ Crapo‚ & McClellan‚ 1999); 5-6 hours at normal O2 concentration (21%)‚ 30-90 minutes at 100% O2 and 30 minutes under hyperbaric oxygen conditions (Levine‚ 2003). This is due to the tight binding of CO to Hb. This study used a simple conventional spectrophotometry for assessment and percentage determination of COHb. Hb molecules are easily measured with response to various Hb

the exchange of oxygen and carbon dioxide that occurs during animal respiration. Normal atmospheric pressure at sea level is the total pressure that a column of air above the surface of the Earth exerts (760 millimetres of mercury‚ or 1 atmosphere). The total pressure is the sum of the pressures that each gas—mainly nitrogen‚ oxygen‚ and carbon dioxide—would exert alone (the partial pressure of that gas; see respiration: The gases in the environment). As an animal breathes‚ oxygen moves from the environment

In the article‚ “Oceans Are Losing Oxygen—and Becoming More Hostile to Life” by Craig Welch‚ climate change is affecting the lives of all kinds of sea creatures. This article explains how climate change‚ and the warming of ocean water‚ has began taking oxygen out of the water. This means that many fish species have shrunk because of this loss of oxygen. The warmer water speeds up the metabolism of these fish‚ which makes them breathe in more of the oxygen. A couple of scientists from the University

The tires absorb moisture from roads while in motion. It can also pull carbon dioxide out of the air to fuel the moss’ photosynthesis which has clean oxygen as its byproduct. Absorbing 4‚000 tons of C02 a year Goodyear’s estimate is that the Oxygene‚ if all the 2.5 million vehicles in Paris switch to the brand‚ could produce 3‚000 tons of oxygen and absorb more than 4‚000 tons of carbon dioxide annually. The tire‚ however‚ goes beyond cleaning the air.
