After working for 10 days at Bellevue Hospital in New York, Dr. Richard Levitan decided to share what he learned about Covid-19. Too many patients were presenting to hospitals with low oxygen levels, putting them at risk of serious complications and death.

But a simple home device called a pulse oximeter can help alert patients to seek help early, he said.

“In the hospital, when I’m trying to decide who to send home, a big part of the criteria is ‘What’s your oxygen? What’s your pulse?'” said Dr. Levitan from his home in New Hampshire, where he just finished self-quarantine as a precaution. “With a monitor temperature and thermometer, Americans can be prepared and diagnosed and treated before they get seriously ill.”

Health officials are divided on whether home heart rate monitoring should be recommended on a widespread basis during Covid-19. Reliability studies show mixed results, and there is little guidance on how to choose one. But many doctors are advising patients to get one, making it the go-to device for this pandemic. We’ve answered common questions about the device, how it works and what to do with the information it provides.

A pulse oximeter is a small device that looks like a chip or a large clothes pin. You stick your finger in properly (most don’t need the side of your fingernail), and after a few seconds, it lights up with numbers showing your blood oxygen level and heart rate. Most healthy people will have oxygen readings around 95 to 98 percent. Some people with existing medical conditions may have lower-normal readings. You should consult your doctor if the number drops to 93 or 92 or lower.

The device will also show your heart rate. The normal resting heart rate for adults is between 60 and 100 beats per minute, although athletes with high cardiovascular fitness will have lower heart rates.

Blood oxygen level is an indicator of the amount of oxygen circulating in the blood. It is a measure of the oxygen carried by red blood cells from the lungs to all parts of the body. Our body’s organs and vital systems need the right amount of oxygen to function effectively. There can be negative consequences if the oxygen level is too low or too high. Low blood oxygen levels can be a warning sign that urgent medical care is needed. Maintaining the proper level of oxygen in the blood is important for maintaining good health. Similar to blood pressure or blood sugar level, our blood oxygen level plays a major role in maintaining good health.

Our blood cells are oxygen carriers, and each blood cell can carry about four molecules of oxygen from the lungs to different organs of the body. We can use a pulse oximeter to estimate blood oxygen levels. This non-invasive device works by sending infrared rays into capillaries when placed on a fingertip or ear. It estimates the oxygen level by measuring the reflected light.

What should your oxygen level be? Oxygen saturation is considered normal if it is between 95% and 100%. If oxygen levels fall below this range, one must seek medical advice.

Oxygen levels between 91% and 95% may indicate a medical issue. People with an oxygen level below 95% must seek medical advice immediately.

An oxygen level below 90% is very concerning, indicating a medical emergency. This condition is called hypoxemia. Immediate medical help must be given to the person.

If the oxygen saturation drops below 85%, severe lack of oxygen affects the brain. A person may experience changes in vision and loss of consciousness.

When the oxygen level in the blood drops below 80%, the brain, liver, and other vital organs of the body are affected.

Cyanosis develops when blood oxygen saturation is below 67%. It is a condition characterized by a brownish color on the skin or mucous membranes due to lack of oxygen.

Pulse Oximetry: Uses And Benefits

Several factors affect the body’s ability to maintain the correct level of oxygen. Some possible causes of low blood oxygen levels are as follows.

Hypoxemia refers to a condition when the concentration of oxygen in the blood is abnormally low. Depending on the low level of oxygen in the blood, the symptoms of hypoxemia can vary from person to person. Some of the symptoms of low blood oxygen levels include:

When the oxygen level is too low, it causes cyanosis. A person gets a brown color of the skin around the lips, nails, etc., due to the lack of oxygen in the blood.

What Is The Normal Oxygen Level In Human Blood

The normal level of oxygen in the blood is generally between 95% and 100%. However, many times we may not experience any symptoms even if the oxygen saturation is slightly low. Therefore, monitoring of blood oxygen levels is important, especially for people with heart or lung problems. There are several ways to check the oxygen level. We can check the oxygen saturation level using a pulse meter, a simple, over-the-counter device. It is a painless, non-invasive, and simple way to check blood oxygen levels used at home and in hospitals. Other methods used in hospitals by health care providers include arterial blood gas measurements and other respiratory tests.

What’s A Normal Blood Oxygen Level, How To Measure

With proper medical advice along with changes in lifestyle and dietary habits, we can maintain proper levels of oxygen in the blood and prevent them from decreasing. Health professionals recommend the following to increase the oxygen content of the blood.

Vital organs in the body work efficiently with the right amount of oxygen in the blood. It is important to monitor blood oxygen saturation levels and consult your health care provider if levels drop. Early diagnosis and proper treatment are the keys to preventing complications and ensuring good health. Make an appointment with experts in the field to get proper medical advice. You may have been told by your doctor to use a pacemaker because you are recovering from COVID-19, or because you are a patient who is at high risk of suffering. and COVID-19. Using a pulse monitor is a great way to make sure your breathing rates don’t get worse.

It measures how your heart beats and also checks how well you breathe, it does this by checking how much oxygen is in your blood.

The ideal oxygen level is between 96% and 99% and the ideal heart rate is between 50 and 90 beats per minute (bpm).

Oxygen levels can be low in some people with lung conditions, even when they feel well. If you have an existing lung condition, please consult your doctor about what your reading should be.

The best way to monitor your heart rate and oxygen level is by reading three times a day at the same time each day and keeping a diary of each reading. Download the measurements diary by clicking here.

What Is The Normal Oxygen Level In Human Blood

Basically, pulse oximetry is a painless, non-invasive way to measure the oxygen saturation in a person’s blood.

Components Of Blood (article)

Oxygen saturation is an important measure of how well the lungs are working. When we breathe in air, our lungs deliver oxygen to tiny blood vessels called capillaries. In turn, these capillaries send oxygenated blood to the heart, which then pumps it through the veins to the rest of the body.

Our organs need a constant supply of oxygen to function properly. When the ability of the lungs to transport oxygen into the blood is impaired, the diffusion of oxygen into the blood decreases, thereby endangering our organs. A pulse oximeter can quickly detect this drop in oxygen
