A healthy blood oxygen level is 75–100 mm Hg, or 95–100%. Low blood oxygen levels, known as hypoxemia, may be a cause for concern.
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.
