Cover image of Best Pulse Oximeters

Why is a pulse oximeter so crucial to medical professionals? It is a tool used daily in hospitals and measures the oxygen hemoglobin in a person’s blood supply. As for the name, the device measures the pulse as a part of a medical checkup. You can get the device for home use. Also, you can monitor your oxygen levels as and when required. They are also an excellent product for sports personnel to monitor the pulse rate during a workout. 

Doctors need to analyze the human body thoroughly during the examination to determine the health of the individual. The human body requires oxygen to function, and it is vital to know if there are any problems related to the same. To clarify, none of the organs of the human body can survive without oxygen-rich blood. The brain especially requires oxygen and deprivation, which could lead to long term problems with the body. The Pulse Oximeters measures the amount of oxygen in the body for doctors to determine if the person is healthy. It is used after surgery, and also to check if a medication is working. 

If oxygen levels in your blood is of concern, you will need a pulse oximeter to determine the accurate reading of your blood oxygen level. The device is easy to use, and results come in quickly. To get the best, you will have to purchase the top tool in the market, and we have a list to help you through the rough. 

What are ‘Pulse Oximeters’?

A Pulse Oximeter is a device that measures oxygen saturation in a person’s body. By this, we mean that it measures the level of oxygen in the blood without the need for invasive means. You can clip the device on your finger, toe, or earlobe. It is a handy device for athletes who continuously monitor their heart rates. Especially during a workout, these athletes can see when they are pushing themselves over the limit. Many experts suggest constant monitoring, especially while mountain climbing and other adventure sports activities. 

When blood flows from the heart to different parts of the body, it carries fresh oxygen along with it. If there is insufficient oxygen in the blood, your organs and tissues will not be adequately oxygenated. Consequently, it could lead to health issues. The device is vital to individuals who receive oxygen from an external source like concentrators or tanks. Knowing how much oxygen is needed to avoid hazardous health issues is the primary goal of this device. 

In addition to the primary function, you can check heart rate status, blood flow, and necessarily monitor the health status of an individual. You can also check the pulse rate of patients quickly. As a result of the convenience, this device allows Doctors to substitute blood gas tests with Oximeters. Doctors and other medical experts no longer need to use invasive measures to check the oxygen level in blood. And as health is the primary function, you need to check on the best pulse oximeters available online. 

How Does a Pulse Oximeter Work?

The principle that the device works on is the wavelength of light that goes through the blood. From here, the Pulse Oximeter analyzes this wavelength and determines how much blood has been oxygenated and de-oxygenated (The ratio between both is called oxygen saturation). Also, it measures the percentage of arterial oxygen carried in the blood known as SpO2. 

The clip part of the device is attached to the most transparent parts of the body, i.e., the ear lobe, finger, or toe, and the light source emits a broad spectrum of light. Deoxygenated blood absorbs more red light, and oxygenated blood absorbs infrared light. The receiving end calculates the wavelength of light and processes the components and provides results. 

Many factors can affect the result, such as ambient lights, the size of the individual’s finger, and the ability of the tissue to absorb light. But the device can calibrate the readings and provide a precise result. Additionally, the Heart Rate is simultaneously calculated and allows doctors to carry out a complete examination. 

Types of Pulse Oximeter 

1) Wrist Pulse Oximeters – Just like wristwatches, these are worn around the wrist and monitor the beats of a person’s pulse. They are the best choice for patients who need to be monitored by doctors throughout the day, especially during sleep. Doctors attach the probe to the patient’s finger, and it displays the result on the watch screen. These devices are very convenient. Most of them have USB connectivity and Bluetooth. 

2) Finger Pulse Oximeters – These devices are clipped on the fingers of the user and are very convenient and portable. The display screen is on the probe itself. As a result, it shows results instantly and continuously. It is usually battery operated and suitable for home use. Many doctors use them on patients as well to check blood oxygen levels. 

3) Handheld Oximeters – The biggest of the three is the handheld pulse oximeter. The device has a probe and a handheld display screen. The probe is placed on the person’s finger, and the blood oxygen levels are shown on the screen. A cable connects both parts. The results are very accurate. Because of this, the device is used in primary medical services like EMS, medical institutions, ambulances, hospitals, and other medical departments.

  • Secondly, we should keep in mind the activities in which the individual is involved, such as sports or fitness activities, etc. 
  • Lastly, the health and surroundings of the person using the device

With these in mind, the normal ranges of a human being are:

  • For Heart Rate – 60 – 100 BPM
  • Oxygen Saturation – 90-100 %

Benefits of Using a Pulse Oximeter

1) For Adventure Sports Activities – The pulse oximeter should be attached to you so it can alert you when oxygen-deprived. The high altitude activities such as mountain climbing, skydiving, hand gliding, and other related sports can lead to the lower oxygen level in the blood—the device can monitor this. 

2) COPD – If you have COPD, you need this device at all times. It is crucial to make sure your lungs are providing enough oxygen to your body. And this device can help monitor the same. It helps doctors get alerts for patients that need medication and is a great way to monitor their SpO2 Levels. 

3) Asthma – Patients can get alerted before the attack takes place and keep their inhaler ready. 

4) Sleep Apnea – The device can monitor the blood saturation level and is a great way to combat severe snoring. 

In the event of an emergency, the device can alert doctors and nurses in a hospital when there is a problem with the patient’s oxygen levels. 

Precautions and Warnings When Using Pulse Oximeters

There are no side effects of using a Pulse Oximeter. As long as the device provides an accurate reading, you are in good hands. But there are certain elements to consider, such as:

1) Dark Skin – Tests have revealed that the devices overestimate the concentration of blood oxygen. As a result, these tests have confirmed that people with darker skin tones have a different reading than people with lighter skin tones.

2) Toe and Finger Nail Paint – Paint on nails can alter the readings and cause problems for the device. In the end, the SPO2 reading may not be on point. 

3) Bright light – Sunlight or direct light falling over the device can alter the reading and disrupt the accuracy. So make sure the room is dim for accurate results. 

4) Carboxyhemoglobin – The tool cannot calculate the carbon dioxide level in the blood. Therefore, you should use gas-blood analysis to determine the spike in carbon dioxide levels in the blood. 

5) Also, Make sure the patient is not Shivering as it could result in a wrong reading. 

You should go to the emergency room if your SPO2 level is less than 80%. If the results are repeated, it may prove fatal. Make sure the device does not have any scratches or damage as it could deter the device from accurate readings. 

Buying Guide For The Best Pulse Oximeters
