What is a Pulse Oximeter?

Oxygen is important for humans to live a life. Without oxygen, one can’t survive, and the condition of the person becomes fatal without oxygen. Once you breathe in, oxygen goes into your body and passes through your blood vessels. Oxygen carries blood to your heart for regular functioning. So, human beings must have to breathe enough oxygen for maintaining proper health. To measure this saturated oxygen level in your blood, doctors use Pulse Oximeters.

Pulse Oximeters are small clip-on devices that can be attached to your finger or foot or wrist, etc. One can use this device on your body parts where it can read the flow of blood.

Why Are Pulse Oximeters Important In Current Times?
In a human body, oxygen saturation level may decrease for various conditions such as

▪ Pneumonia
▪ Suffocation
▪ Drowning
▪ Disorders like lung cancer, infections in the lungs, and emphysema
▪ Anesthesia
▪ Asthma
▪ Chronic Obstructive Pulmonary Diseases (COPD)
▪ Breathe in poisonous chemicals
▪ Sleep abnormalities
▪ Cardiac failure
▪ Choking, etc

In all these above conditions, pulse Oximeters help doctors to detect and monitor the oxygen saturation level to treat patients.

COVID-19 Pandemic:

In the current times, we are fighting against the deadly Corona Virus. As everyone knows, this virus creates a pandemic situation among people across the world. The common symptoms of this COVID-19 are fever, cold, cough, and breathing problems. As the deadly virus directly attacks our respiratory system of the human body, one can’t breathe normally leading to many fatalities. During this COVID-19 pandemic, Pulse Oximeters are an absolute must for doctors to detect the patients’ oxygen levels.
Pulse Oximeters usually detect low blood oxygen levels in patients, and such condition is known as Hypoxemia. Now, this condition is one of the early symptoms of the Corona Virus. Thus, Pulse Oximeters become necessary to detect this deadly virus in early times. That is why pulse oximeters are an absolute must in current times.

Other Common Uses of Pulse Oximeter:

In addition to the above uses, the device has other common uses including:
1. To check the oxygen levels of the patients during and after surgeries using sedation
2. To know how the newly given lung medicines are working
3. To identify if someone needs help to breathe properly
4. To access whether the patient stops breathing during their sleep such as Sleep Apnea
5. To evaluate whether the new oxygen therapy works effectively for patients
6. To monitor the oxygen levels for those involved in physical activities
7. To detect whether the use of a ventilator is effective for patients
Working of a Pulse Oximeter:

To take a pulse oximeter reading, the device is kept on your finger or toe or earlobe to detect the oxygen level. The device passes a small beam of light on the finger through the blood to detect the amount of oxygen. It sends a beam of light through a transparent area of your body. The device gives measurement with the changes in the absorption of light in deoxygenated or oxygenated blood. The device is entirely non-invasive, accurate, and painless to use for patients. Thus, you will get both the heart rate and oxygen saturation level using a pulse oximeter.

Benefits of a Pulse Oximeter:

▪ A pulse oximeter is a must-have device in emergency rooms, ambulances, operating rooms, and in other health facilities.
▪ Pulse oximeters are crucial for people dealing with oxygen saturation problems.
▪ They are best in providing great feedback about the use of ventilators and new oxygen therapies.
▪ Doctors use this device as a part to conduct a stress test.
▪ They are effective in treating respiratory and cardiovascular problems
Thus, with the above article, one can understand the use of pulse oximeters and how they are helpful in current times.
