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.
The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%.aving a pulse oximeter in these cases will allow you to monitor your blood oxygen level and know when you need to increase your supplemental oxygen flow rate. Ask your health care provider what oxygen saturation number(s) they want you to maintain.
