What is SpO2?
Recently, pulse oximetry (SpO2) has received increasing attention from the public because some doctors recommend that patients diagnosed with COVID-19 monitor their SpO2 levels at home. Therefore, it makes sense for many people to wonder “What SpO2?” for the first time. Don’t wo...Read more -
What is a pulse oximeter?
A pulse oximeter can measure the amount of oxygen in someone’s blood. This is a small device that can be clamped on a finger or another part of the body. They are often used in hospitals and clinics and can be purchased and used at home. Many people believe that oxygen level is an importan...Read more -
Should you buy a pulse oximeter?
The popularity of COVID-19 has led to a surge in the sales of pulse oximeters. Pulse oximeters measure the oxygen saturation in red blood cells by emitting light from the fingertips and reading the amount of absorption. The normal range is usually between 95 and 100.This is a handy little device ...Read more -
Pulse oximetry-a little knowledge can be dangerous
Let us directly understand some knowledge about pulse oximetry, which seems to have become news these days. Because just knowing the pulse oximetry can be misleading. The pulse oximeter measures the level of oxygen saturation in your red blood cells. This handy tool is usually clipped to the end ...Read more -
What is a pulse oximeter and what can it measure?
Pulse oximeter is a painless and reliable method for clinicians to measure human blood oxygen levels.A pulse oximeter is a tiny device that usually slides over your fingertips or clipped to your earlobe, and uses infrared light refraction to measure the degree of oxygen binding to red blood cells...Read more -
Understand the normal oxygen level of SpO2
How does the body maintain normal SpO2 levels? Maintaining normal blood oxygen saturation is essential to prevent hypoxia. Fortunately, the body usually does this on its own. The most important way for the body to maintain healthy SpO2 levels is through breathing. The lungs absorb the oxygen that...Read more -
What is the normal oxygen saturation level?
The normal oxygen saturation is 97-100%, and the elderly usually have lower oxygen saturation levels than the young. For example, someone over 70 years of age may have an oxygen saturation level of about 95%, which is an acceptable level. It is important to note that the oxygen saturation level c...Read more -
What is blood oxygen level?
Blood oxygen level (arterial blood oxygen content) indicates the level of oxygen present in the blood flowing through the arteries of the body. The ABG test uses blood drawn from arteries, which can be measured before it enters human tissues. The blood will be placed in an ABG machine (blood gas ...Read more -
How to correctly use pulse oximeter to measure oxygen?
Pulse oximeters used to assess the oxygen status of patients in various clinical settings have become more and more common monitoring equipment. It provides continuous, non-invasive monitoring of hemoglobin oxygen saturation in arterial blood. Each pulse wave will update its result. Pulse oximet...Read more -
What is the relationship between pulse and blood oxygen saturation?
In the late 1990s, several studies were conducted to evaluate the accuracy of non-professionals, first responders, paramedics and even doctors in assessing only the presence of pulse. In one study, the success rate of pulse recognition was as low as 45%, while in another study, junior doctors spe...Read more -
How does a pulse oximeter work?
Pulse oximetry is a non-invasive and painless test that measures the oxygen level (or oxygen saturation level) in the blood. It can quickly detect how effectively oxygen is delivered to the limbs (including legs and arms) furthest from the heart. A pulse oximeter is a small device that can be cl...Read more -
How to understand oxygen saturation？
Oxygen saturation refers to the degree to which hemoglobin in red blood cells bind to oxygen molecules.There are two common methods of measuring blood oxygen saturation: arterial blood gas (ABG) test and pulse oximeter. Of these two instruments, pulse oximeters are more commonly used. The pulse ...Read more
