Oxygen is essential in sustaining life. When your body starts losing considerable amounts of this highly reactive element, you (or the people around you, for that matter) need to spring into action or else face serious health repercussions. Oxygen saturation shouldn’t fall below 95%. This is why it can be a good idea to have a look at the Best Pulse Oximeter Reviews so you can find a good one to have around the house.

If allowed to go unchecked, brain damage or heart failure are bound to occur.

Due to the high level of urgency of maintaining the recommended oxygen saturation levels of patients, pulse oximeter units were introduced in hospitals in 1985 to help with treatment of pneumonia, neonatal blindness, and many other illnesses. Today, they continue to save countless lives on a daily basis, not just in hospitals but also in people’s day-to-day activities.

Luckily for them, there are many excellent portable pulse oximeter units out in the market.

Staying Safe at Home: Correct Usage of Pulse Oximetry Tools


Lack of oxygen in the body can be an incredibly dangerous situation, leading to brain damage, heart failure and even death. Anytime oxygen saturation levels in the body drop below 95%, serious deterioration of bodily systems is likely to occur.

Pulse oximetry is one of the most important tools that health care providers use to keep your oxygen levels in a safe range, and theyre also available for use within the home. Heres a quick overview of how to use them correctly.

Types of pulse oximetry devices

There are a variety of fingertip devices on the market that will measure your bloods oxygen level, each of which have pros and cons. One of the units that is trusted by professionals around the country is the CMS 50-DL, a lightweight and inexpensive option with a variety of features including long battery life, an intuitive and easy to read display and it also comes with a neck or wrist cord and storage case.

It can be a bit slower than some other options, but the pros seem to far outweigh the cons on this particular product. Similar products include the Fingertip Pulse Oximeter from Easy@Home, and the Concord Emerald Fingertip Pulse Oximeter.oximeter

More Accurate Options

More accurate options can be a little more pricey, but the Acc U Rate Premium Pulse Oximeter delivers, with the ability to measure both pulse rates and oxygen saturation in an instant–with one-button simplicity. A rotatable OLED display allows for operation from all angles, a bonus for sports enthusiasts who need to watch their oxygen levels.

What can throw off readings?

Pulse oximetry is generally measured on a fingertip, and there are a variety of factors which can give you inaccurate or misleading readings. In general, to use the units you will place your palm out, insert your index finger into the measurement unit, and wait a moment to receive accurate pulse rate and oxygen level readings.

Tracking your daily oxygen levels is always encouraged so you can see what your normal range is. The use of nail polish and artificial nails can seriously impact the functionality as accuracy depends on measuring a good blood flow through the tissues. Cold fingers can also impact the readings, providing a reduced, low or abnormal reading so it is recommended that you rub your hands together to warm them up or wash them under warm water before attempting to take a reading.Best Pulse Oximeter

Another factor that reduces the blood flow to your fingers and other extremities is smoking. Since the pulse oximeter is measuring the absorption of specific wavelengths of light, not only can smoking reduce your oxygen levels but it can also color the fingertips causing irregular results.

Patients with hypotension, hypovolaemia or hypothermia may also have poor results based on the level of their condition. Cardiac arrhythmias can also cause inaccurate measurements, as well as intravenous dyes, and tourniquets or pressure cuffs above the site of the measurement.

A final factor that could obstruct accurate results is the presence of dried blood, which could diffuse light which hits it, or having the sensor dislodged before accurate results are calculated.
