In some people, the right thumb may also work well. We are still learning about how COVID affects the lungs. Things like dark nail polish or cold extremities can cause the pulse ox to read lower than normal. Normally, a PaO 2 reading below 80 mm Hg or a pulse ox below 95 percent is considered low. If someone's oxygen saturation is dangerously low, they will need oxygen therapysometimes urgently. Your cells can adapt to a lack of oxygen when the deficiency is small. Below normal: A below-normal blood oxygen level is called hypoxemia. This can lead to a decrease in oxygen levels in your blood, a condition known as hypoxemia.

Stationary pulse oximeters have the highest measurement accuracy, yielding, perhaps, to a laboratory blood test. Blood oxygen levels are often classified as low, normal, or high, and typically range from 75-100 millimeters of mercury (mmHG). In this case, medications that improve heart function, such as beta-blockers for heart failure or prescription medications to treat heart arrhythmias, can help improve oxygenation. It is important to note that the blood oxygen level typically remains fairly normal even in the midst of a significant asthma exacerbation.
