Meat producers have fed growth-promoting antibiotics to food animals for years. Recently, scientists have raised concerns that, in conjunction with the general overuse of antibiotics in humans, this use of sub-therapeutic levels of antibiotics in food animals may lead to serious health risks for people.
Though the pulse oximeter actually measures the saturation of oxygen in your blood, the results are often used as an estimate of blood oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low.
Hemoglobin is a protein in the blood that carries oxygen to the tissues. A light sensor is used which is commonly placed on a fingertip. Pulse oximetry is not as accurate as a blood gas and can be influenced by temperature and circulation. The normal oxygen saturation is 95-100%.ven though oxygen is a gas, we have to think of it in terms of being a liquid â if the pressure at the tank remains constant (which it does until the tank has less than 500 psi), the liter flow, 2 LPM (liters per minute), 3 LPM, etc. will remain constant.
