By measuring the light, the pulse oximeter determines the oxygenation of your blood. Hemoglobin absorbs light waves when it carries oxygen. Additionally, the pulse oximeter uses the light data to measure blood vessel size and non-oxygenated hemoglobin. Within seconds, the pulse oximeter uses this data to determine your oxygenation level. An Oximeter is a lightweight gadget that lets you keep track of the amount of oxygen saturation in the body. This device will let you know about the oxygen information in your body, so you can compute how much oxygen presently in the blood. The maker has a screen that will let you see the percent of oxygen in the blood coming from your heart. Zacurate Pro Series 500DL Review. Great Price We selected the Zacurate Pro.
The Pros and Cons of Using a Pulse Oximeter
Are you getting enough oxygen when you breathe?
Whenever I go into my doctor's office for a checkup, they put a little clip on my finger. It looks like a thick clothespin or something you would use to secure a bag of chips. Within a few seconds, some numbers pop up.
That device is called a pulse oximeter. It measures heart rate and blood oxygen levels. It works by shining a light on the area being measured and calculating the percentage of oxygen in red blood cells, also known as oxygen saturation.
Red blood cells carry oxygen from your lungs to your organs. A normal range for most healthy people is between 95 and 100 percent. However, medical conditions can lower that number. If you have asthma, anemia, are experiencing an allergic reaction, COPD, emphysema, pneumonia, have sleep apnea or are going through cancer treatments your number can be lower. Smoking and vaping can bring that number down as well.
Pulse oximetry is a method for measuring and monitoring a patient's oxygen saturation. It gives the readings of peripheral oxygen saturation and arterial oxygen saturation. The sensor device is placed on a thin part of a person's body, earlobe or fingertip, in the case of an infant across the foot. Add finger pulse oximeters to the list of things that have become suddenly scarce during the coronavirus pandemic, which has already changed our lives in myriad ways.
A low reading can also be an early warning sign you're getting sick. A level of 92 percent indicates a condition known as hypoxemia. That may mean you're not getting enough oxygen to keep your cells and your body healthy. Readings below 90 percent are considered abnormally low and may indicate a clinical emergency.
Consistently low readings indicate your body is working harder than it should, and in extreme cases can cause permanent damage to organs. If a medical professional documents regular readings below 88%, medicare will pay for oxygen therapy and oxygen equipment.
In the last few years, the price of pulse oximeters has dropped so significantly, you can now pick up a reasonably reliable one for around $30. That means you can track your oxygen levels at home, whenever you want.
There are some benefits to home monitoring.
People who aren't sleeping well could wear one overnight. A drop or multiple drops in oxygen levels could indicate sleep apnea or severe snoring.
Anyone taking drugs that affects breathing can use one to learn if there's a problem. Regular monitoring can also alert people to chronic respiratory or cardiovascular conditions. Then doctors can decide if supplemental oxygen is necessary.
Do masks prevent you from getting enough oxygen?
I decided to get one to answer a question many of my clients have. Since wearing a mask is currently required while training, I wanted to make sure everyone was getting enough oxygen during their workout.
I started with my trainers. I asked them to take their reading before and after an intense cardio session. We used different thicknesses and types of masks, including one session with a fitted N95 respirator. The results surprised me.
With 10 different sessions, the average drop in oxygen levels was less than 1%. In two people, the oxygen levels increased in the final reading. Keep in mind that the accuracy of these devices can vary by 2%. So in practical terms, there was no statistical change after 30 minutes of intense cardio, even though they were breathing through a mask.
The results I obtained, cannot be used as a benchmark for everyone. The testing wasn't done under rigorous clinical conditions, we had no control group and the sample size was too small. The value was the information provided to those involved in the test. After going over results with a doctor, they felt reassured their mask wearing workouts weren't hurting them.
Anyone that's concerned about oxygen deprivation from wearing a mask, should definitely consider testing themselves with a pulse oximeter. If for no other reason than to put your mind at ease.
If you're considering monitoring yourself, you need to be aware of several issues.
If your fingernails are too long, your fingers may not fit properly in the machine and you'll get a bad result. Dark nail polish and dirty fingers can also cause inaccurate readings. Testing on someone with darker skin can over-estimate the reading if the actual number is below 80%. Test where skin color is lightest.
Medical issues can create false readings. High levels of carbon monoxide can throw the readings off. People suffering from smoke inhalation, heavy cigarette smokers and someone with carbon monoxide poisoning shouldn't use a pulse oximeter.
Someone suffering from anemia or anyone with blood volume deficiencies like hypovolemia, hypotension and hypothermia may not get accurate readings. High levels of methemoglobin, a form of hemoglobin that does not carry oxygen can also cause problems.

Testing on anyone with cold hands or in a cold environment can be challenging. The same is true if you're testing around particularly bright lights. Since a pulse oximeter uses light to get the reading, really bright lights could interfere.
What fingers to use.
Health technicians typically place the device on the index fingers. One clinical study showed the highest reading came from the third finger on the dominant hand. That means right handed people should use the middle finger on the right hand and left handed people should use the middle finger on the left hand. Whichever finger works best you should continue to use so your results are consistent.
Don't just buy a pulse oximeter and blindly believe the results. If you want to use one, ask your doctor if using one might be beneficial for you. Check to see if you have underlying conditions that would make the results invalid. If your doctor recommends one, ask about the best way to use it in your particular situation.

With the ongoing pandemic of the COVID-19, the recent report from WHO emphasizes that 'Oxygen therapy is the major treatment intervention for patients with severe COVID-19', 'All countries should make the best use of pulse oximeters and medical oxygen systems to treat the patients.' In the WHO's manifestations classification of the coronavirus disease, it is further mentioned that under the room air environment, an adolescent or adult with SpO2 reading <93% or children with SpO2 reading<90% are recommended to seek medical attention immediately.
Blood oxygen saturation (SpO2) is one of the important indicators of the severity of coronavirus. It can monitor the oxygen concentration in the blood of a patient and alert a medical caretaker when the oxygen level falls below the acceptable limits for fast response. These devices are necessary tools in situations where a patient's blood oxygen saturation needs to be monitored. If you have symptoms of dyspnea, fast breathing, and hypoxemia that are commonly seen on early stages of coronavirus patients, it is recommended to see a health professional and conduct home self-monitoring.

The fingertip pulse oximeter introduced by Leadtek uses a lightweight and non-invasive design to detect the oxygen saturation in human blood. Using optical technology, it absorbs red light and infrared light through the perfused tissue to quickly obtain accurate blood oxygen saturation (SpO2). The built-in anti-motion algorithm can still maintain the accuracy of measurement data in emergency situations. It is convenient for people to monitor blood oxygen level anytime and anywhere, whether it is the diagnosis in the medical institution or the personal home monitoring.

The fourth edition of the Novel Coronavirus Pneumonia Diagnosis and Treatment Plan also mentioned that further clinical classifications will be made. Based on whether there are clinical symptoms, whether there is lung inflammation, the severity of lung inflammation, whether there is respiratory failure, shock, or organs failure, the classifications include regular form (fever, respiratory tract symptoms, imaging shows visible lung inflammation), severe form (shortness of breath, RR≥30 breath / min, oxygen saturation < 93% at rest condition, arterial oxygen partial pressure (PaO2)/ fraction of inspired oxygen (FiO2) < 300mmHg), and critical form (respiratory failure occurs and mechanical ventilator is required, shock, combined failure of other organs that requires ICU monitoring). Therefore, the monitoring of blood oxygen saturation is very important to preventing and controlling of the coronavirus. It is recommended to keep an oximeter at hand to monitor and care for your lung health at all times.
