DECISIONS SERIES Oxygen Saturation A Guide to Laboratory Assessment BY SHANNON HAYMOND‚ PHD uman life depends on the oxygen transport by hemoglobin. In healthy patients‚ the majority of molecular oxygen (O2) is bound to hemoglobin and only a small fraction is dissolved in blood. But in patients with respiratory problems or certain metabolic and genetic disorders‚ the fraction of oxygenated hemoglobin can fall to dangerously low values. Therefore‚ laboratory assessment of oxygen saturation (SO2)—the

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

mechanical ventilation is a method to mechanically assist or replace spontaneous breathing. Mechanical ventilation‚is typically used after an invasive intubation‚ a procedure wherein an endotracheal or tracheostomy tube is inserted into the airway. It is used in acute settings such as in the ICU for a short period of time during a serious illness. It may be used at home or in a nursing or rehabilitation institution if patients have chronic illnesses that require long-term ventilation assistance

benefits to having a gold fish? The fish would help teach me responsibility‚ with no trips to the vet‚ along with no hair on the furniture. Now wouldn’t that make it worth it? As a parent the first question that may be asked is how will a goldfish teach responsibility? While you do still have to feed it and clean the fish bowl‚ which may require some help‚ the care of a gold fish is not that hard. Oh sure you think the fish might not get fed a day or two. To your surprise statistics show

Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around

On the periodic table‚ oxygen is the 8th element. It is located in period 2 and group 16. Oxygen is classified into many things. For example‚ on the periodic table‚ oxygen is classified as a nonmetal gas with an atomic number of 8 and atomic weight of 15.9994. In addition‚ it has 6 valence electrons. The symbol of oxygen is O and oxygen has 8 protons‚ 8 neutrons‚ and 8 electrons. The electron configuration of oxygen is 1s2‚ 2s2‚ 2p4. Oxygen had been produced by several chemists prior to its discovery

Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism‚ the means by which animals derive the energy needed to sustain life. Furthermore‚ oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores‚ earths‚ rocks‚ and gemstones‚ as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic

Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic
