Best Pulse Oximeters 2024 – For Self Blood Oxygen SpO2 Measurement

Pulse Oximeters are a group of medical devices that measure the arterial blood oxygen saturation (SpO2) levels of your body. These devices operate by emitting a large spectrum of Infrared lights and measure oxygen levels based on the reflections that are picked up by the sensor. Oximeters are utilized extensively in hospitals, clinics, and homes for their intended function. Let me outline some fundamental information for you:

  1. For anyone with respiratory problems such as asthma, emphysema, or COPD – among others – keeping up to date with SpO2 levels is a key part of managing their condition effectively. In these cases, there’s no substitute for Sp02 monitoring devices which are highly valuable tools to keep on standby. In terms of understanding the readings they provide; experts consider oxygen levels above 95% to be indicative of good health amongst adults while anything beneath the threshold of 92% is considered concerning overall.
  2. Crucially however when dealing with someone who has chronic obstructive pulmonary disease (COPD) & other similar conditions we should be aiming for a minimum threshold figure of around the 90% mark before taking further action – seeking immediate medical advice if necessary.

How to read Pulse Oximeter Results?

A Pulse Oximeter is used to track your oxygen levels. It works and performs efficiently when attached to your index or middle finger (of either hand). The reading is accurate when hand is kept steady and takes a minute to display the reading/results. After the results or readings are displayed on the Pulse Oximeter, you’ll get to know your current SpO2 levels. According to Mayo Clinic, normal Pulse Oximeter readings range between 95 to 100%. Values under 90 are considered to be low, indicating deprivation of SpO2 or oxygen levels in your body. This also indicates the need for the requirement of supplemental oxygen. Therefore, if you’re administering a Pulse Oximeter at home to check your SpO2 levels, you need to watch out for the ranges. If your SpO2 levels are above 90, then it means you have sufficient oxygen level. If the results show value below 90, then you need supplemental oxygen, as your body is lacking the optimal SpO2 levels.

Why should have a Pulse Oximeter Monitor at Home?

A Pulse Oximeter is a must-have medical device in these days, especially after the Pandemic. Given how viral infections affect our bodies in this post-pandemic Era, it is important to track your oxygen levels through Pulse Oximeter Monitors, so that you are aware of your current lung health, in terms of SpO2 levels in your body. Additionally, for people who have undergone lung-related issues, including pneumonia, and other viral chest infections, it is crucial to monitor your SpO2 levels, which is why you should have a Pulse Oximeter Monitor at Home. Here are a few Pulse Oximeter FAQs you might want the answers to:

Q1. What is a normal reading on Pulse Oximeter?

Answer: Pulse oximeter Monitors displays your SpO2 results in the form of ranges. The normal Pulse Oximeter reading falls between 95 and 100.

Q2. How do you read the top and bottom of Pulse Oximeter?

Answer: By turning your hand with your fingernails facing towards you. The top reading of the pulse Oximeter displays your SpO2 level, while the bottom displays your heart rate.

Q3. Which finger is used for the Pulse Oximeter Monitor?

Answer: While you may use any finger (of any hand) to determine your SpO2 levels through Pulse Oximeters, it is preferable to use the Pulse Oximeter on your index finger, middle finger or the thumb, as it is believed that it allows the best values for arterial oxygen reading.

Q4. How long should you keep the Pulse Oximeter on your finger for reading?

Answer: It is suggested and also recommended that you keep the Pulse oximeter on your finger for at least 1 minute to ensure maximum result efficacy.

Q5. Will Pulse Oximeter detect Covid-19?

Answer: While the Pulse Oximeter is only used to determine oxygen saturation levels, you cannot solely determine the presence of Covid-19 through Pulse Oximeters alone. However, if you’re seeing results below the average range, then the Pulse Oximeter may serve as an indicator, for separate Covid testing.
