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.
Note that blood pressure readings are expressed as millimeters of mercury. This unit is abbreviated as mm Hg. A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg. Blood pressure that is too low does not supply your body and heart with enough oxygenated blood. Low blood pressure is known as hypotension. If youâre in the normal range, no medical intervention is needed.
