Hypoxia and Hypoxemia – Every Minute You Are Dangerous

Nov 16, 2022

What is hypoxia?

Hypoxia refers to extremely low levels of oxygen in the tissues, and one of the most common causes is asthma, which narrows the airways and limits the normal amount of oxygen you take in resulting in low blood oxygen saturation. People who also have chronic lung disease, anemia, heart disease, or medication often experience symptoms of oxygen deprivation.

What is hypoxemia?

Hypoxemia refers to extremely low levels of oxygen in the blood, which can prevent your body from functioning properly. This happens when you can’t breathe in enough oxygen or the oxygen doesn’t get into your bloodstream. Mild hypoxemia can lead to headaches and shortness of breath, and severe cases can lead to death, so it’s important to monitor your blood oxygen saturation at all times.

The difference between hypoxia and hypoxemia is as mentioned above. Both hypoxia and hypoxemia affect each other, so it is very important to monitor their readings at all times. This is also recommended that you must have your pulse oximeter reason.

5 major factors of hypoxemia

The respiratory and cardiorespiratory function can lead to five factors of hypoxemia: respiratory and blood flow mismatch, delivery disturbance, insufficient oxygen supply, low ambient oxygen content, and blood shunt errors.

1. Mismatch between breathing and blood flow

After the respiratory system inhales oxygen, for the oxygen to flow into the blood, airflow into the lungs and blood flow to the lungs are required to obtain oxygen. If one of them fails, oxygen cannot be absorbed, which is a mismatch between breathing and blood flow.


2. Transmission barrier

Even with good blood flow or airflow, oxygen sometimes has difficulty getting from the lungs to the blood vessels, which can be caused by conditions such as emphysema.

3. Insufficient oxygen supply

You don’t breathe deeply enough or breathe too slowly, causing not enough oxygen to get to your lungs. Many brain tonic diseases can cause insufficient oxygen supply.

4. Ambient low in oxygen

If you’re in an area that doesn’t have enough oxygen, your blood won’t get enough oxygen to run your body, which is often the case at some high altitudes, so having a pulse oximeter at high altitudes is How important.

5. Blood shunt error

Under normal circumstances, deoxygenated blood enters the heart from the right side, then goes to the lungs to obtain oxygen and returns from the left side to supply the whole body. But some people do the opposite. Deoxygenated blood flows in from the left side and does not supply the whole body with oxygen from the lungs. This is a blood shunt error, usually caused by heart disease.

How can a pulse oximeter help you relieve hypoxemia?

During covid-19, almost all countries are calling for the use of pulse oximeters to detect hypoxemia. With the advancement of medical technology and the accelerated development of vaccines, covid-19 is in a period of remission in many areas. However, many patients have very low oxygen index, but they feel fine. By the time an episode occurs, it has become a serious illness.


Usually, patients with shortness of breath and chest tightness have been infected with covid-19 as early as 7 days ago. After seeing the doctor, it was found that the patient’s blood oxygen saturation was as high as 50%, which is generally between 95% and 100% for normal people. Generally, in this case, the patient’s breathing will feel very painful and uncomfortable, and even unconscious, but the actual situation is that the spirit is very good, and it is completely impossible to see that he is suffering from a disease.

Until the patient has passed for several days and suddenly feels shortness of breath or physical fatigue, he is already critically ill at this time. This is why covid-19 is terrible. Some people even need a ventilator to survive. Therefore, many doctors around the world are appealing to patients with mild suspected symptoms to observe changes in blood oxygen saturation through measuring instruments such as pulse oximeters during the one-week isolation period, and judge whether it is a covid-19 disease this morning.

How to solve the hazards of hypoxemia?

Early detection of hypoxia and toxemia is key to reducing harm, which can even lead to death if oxygen levels drop below average. The best way is to record your blood oxygen index, you can record your blood oxygen index through a pulse oximeter.


Yonker Brand Household Fingertip Pulse Oximeter

This is a portable and accurate pulse oximeter that can help you monitor blood oxygen and heartbeat readings. The device is easy to operate and can be used by the elderly and children. The data is stored in real-time and supports Bluetooth function. The super large OLED screen is a better way for you to check the readings. It is also equipped with a night backlight mode for detection anytime, anywhere.
