    Buyer's Guide for Pulse Monitors

    How Accurate Should the Pulse Oximeter Be?

    You want one that provides an accuracy rating of within 2% of blood drawn oxygen levels if this is for medical reasons.

    What is the Best Size for a Pulse Oximeter?

    YMost fingertip monitors are sized for average hands. If your fingertip is smaller or larger than average, you may not get an accurate reading. If this is the case, return the product and get one that best fits your finger.

    Warranty

    A warranty helps with peace of mind once you’ve invested.

    Frequently Asked Questions (FAQ)

    What are Pulse Oximeters?

    Pulse oximeters are small electronic devices that display the oxygen content in your blood. In fact, they show the oxygen saturation, given as an exact percentage of the amount of hemoglobin that is saturated with oxygen at the time of the reading.

    How do Pulse Oximeters Work?

    When you insert your finger into the pulse oximeter, the oximeter sends light through your finger. In fact, it sends two different light beams, each having a different wavelength. One light beam is red while the other is infrared.

    Now, these light beams get absorbed by the finger. However, the extent to which they get absorbed differs significantly depending on the amount of oxygen in blood. Indeed, oxygenated hemoglobin absorbs more infrared light but allows more red light to pass through. On the other hand, deoxygenated hemoglobin allows more infrared light to pass through and absorbs more red light.

    Meanwhile, the pulse oximeter measures the amount of light absorbed by the finger and determines the percentage of oxygen saturation in your blood.

    What are the Normal Pulse Oximeter Readings?

    Normal pulse oximeter readings range from 95 to 100 percent. In fact, readings under 90 percent are considered low. However, this does not mean that a pulse oximetry reading of 90% is safe for you. In fact, a reading of 89% should be worrisome. Whenever blood oxygen levels drop for more than a short period of time, your organs and tissues do not get the oxygen they need to function properly. Over time, this can have serious health consequences.

    Most healthy adults have an oxygen level of 97 to 99 percent.

    Does it Matter What Finger is Used with the Pulse Oximeter?

    In fact, a study reported that using the index, middle, or ring finger with the pulse oximeter gives the most accurate result.

    What can Affect Pulse Oximeter Readings?

    1. 1
      Nail polish or false nails — The reading can’t penetrate the finger to gain an accurate picture.
    2. 2
      Cold hands — Warming up your fingertips for a few minutes helps ensure accuracy.
    3. 3
      Poor circulation
    4. 4
      Poor positioning — Make sure you are still and that your finger is below the level of your heart.

    Can a Pulse Oximeter Help Improve Cardio Workouts?

    First and foremost, to get the most benefits from cardio workouts, the amount of oxygen in your blood needs to be at its peak. Meanwhile, a pulse oximeter shows oxygen levels in your blood.

    So, if you feel you are not doing cardio workouts as well as you would like, use the pulse oximeter to measure your blood oxygen levels before and after the workout. And, if the blood oxygen levels are not as high as they could be, you can take steps to increase blood oxygen levels.

    For example, proper breathing, such as pursed lip breathing, works to increase your oxygen saturation level. In fact, good breathing techniques have been found to improve overall saturation levels by as much as 93 percent.

    Meanwhile, as described in the section below, other ways to improve blood oxygen levels is by eating the right foods.

    How to Increase Oxygen Levels in Blood?

    1. 1
      First, eat more green vegetables like kale, broccoli and celery in order to boost your oxygen levels and hopefully breathe easier.
    2. 2
      Second, a diet low in sodium can lead to increased oxygenation via the kidney and the blood.
    3. 3
      Third, eat iron-rich foods such as meats, poultry, fish, legumes and green leafy vegetables as they can improve iron deficiency, which in turn improves blood oxygen levels.
    4. 4
      Finally, drinking water can increase the amount of oxygen in your body.
