While most people mark their age by the number of birthdays they've celebrated, scientists have long known that the body's organs do not all age at ...

Some COVID-19 patients have experienced silent hypoxia, a condition causing low oxygen levels (without obvious symptoms). This condition can be fatal.

New research shows that even mild, prolonged exposure to low oxygen levels can significantly disrupt the blood-brain barrier (BBB) in aging brains.

Learn about your blood oxygen level, including what it is, how to increase it, and more.

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood ...

The Circul ring has the ability to measure blood oxygen level. Researchers found high area under the curve values with the Circul ring in determining OSA severity vs. polysomnography-derived measures.

A blood sugar chart can help a person know if their glucose levels are within a suitable range. If a person has diabetes, a doctor will make a plan to suit them.

Each patient’s oxygen levels were measured two ways: with a pulse oximeter and with a blood gas analysis — a much more reliable but also more invasive method.

The seals’ ability to detect the amount of oxygen in their blood may help them make diving decisions and avoid drowning.

Age is just one factor that can impact glucose levels. Young children, teens, adults, and senior citizens may have different blood sugar goals. This chart details the clinical guidelines for ...
