How Does a Pulse Oximeter Benefit You?

Detect Problems Earlier

Pulse oximeters can consistently monitor oxygen saturation throughout the day, week, month, or year. Keeping a consistent record of oxygen levels allows both medical practitioners and their patients to detect abnormalities and potential problems before they become life-threatening.

So, in this way, one of the most significant benefits of using a pulse oximeter is that it could just save your life!

Keep Track of Heart Rate

Fitness gurus, exercise enthusiasts, and those just starting a workout routine can all benefit from using a pulse oximeter. Understanding heart rate is critical to achieving the optimal physical benefits from exercise.

If your heart rate is too low, you likely won’t be burning very many calories. But if your heart rate is too high, you could be putting yourself in a dangerous situation, and doing damage to your heart.

A portable, easy-to-use pulse oximeter can be used before, during, and after exercise to help individuals keep track of their heart habits. Remaining aware of your heart rate during and after physical activity is especially critical for ex-smokers, the elderly, pregnant women, and those with pre-existing heart conditions.
