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.
Normal Findings. If 97 percent of your hemoglobin contains oxygen, your blood oxygen saturation is at maximum capacity, UTMB reports. Normal results on a pulse oximetry reading range between 96 and 100 percent of this maximum value.If your pulse oximetry readings fall below 90 percent of maximum, you enter a clinical state called respiratory failure, characterized by inadequate oxygen supplies to your vital organs and body tissue.ormal Findings.
