How Do Oximeters Work, And How Can They Be Used Effectively?

You must have seen doctors and medical professionals checking your oxygen saturation levels during COVID-19 testing. They used a device to clip onto your fingers and note down the readings. The device was none other than an oximeter.

Oximeters measure blood saturation levels in patients suffering from chronic diseases. Athletes and healthy people alike use oximeters to check endurance levels. They are medical devices that tell about the patient's health.

There are namely three types of oximeters- fingertip pulse oximeters, handheld oximeters, and wrist oximeters. Each has its unique use. Buy an oximeter online that suits your needs.

But how do they work? How reliable are oximeters? How can they be used effectively? Let us answer your questions.

How do Oximeters Work?

It is a wonder that a clip-on device can determine what is going on in your bloodstream. Oximeters work on a simple technology.

Light beams can detect the presence of an element in a solution. Oximeters allow small beams of red light to pass through your finger. These beams of light detect oxygen molecules in the red blood cells.

The oxygen molecules absorb this infrared light. The readings tell you how much of the light is absorbed. The more amount of light absorbed, the more oxygen in your blood.

Are Oximeters Accurate?

You must be wondering if the readings are accurate enough. Do not fret because oximeters are reliable machines.

They do not require syringes to draw out blood. You do not need time-consuming tests to check oxygen saturation. On top of this, oximeters also check heart rate and blood pressure.

Buy an oximeter online to save yourself from unnecessary tests.

How Can Oximeters be Used Effectively?

Medical professionals and doctors use oximeters for a variety of reasons. They are a quick and efficient way of determining hypoxia in a patient. Hypoxia can be a symptom of many cardiac and lung diseases.

  • Cardiac arrest
  • Asthma
  • Pneumonia
  • Lung cancer
  • COPD
  • COVID-19
  • SARS
  • Anemia
  • Any other thoracic or cardiac disease

Oxygen saturation levels help doctors to draw out further treatment plans. Use oximeters:

  1. To check if the patient needs an oxygen supply.
  2. To evaluate if a new medicine is working.
  3. To assess oxygen levels during physical activity.
  4. To diagnose sleep apnea.
  5. To monitor oxygen levels in surgery.
  6. To determine the cause of shortness of breath.

If you buy an oximeter online, you can monitor your health and treatment.

What do Oximeter Readings Mean?

Hemoglobin is present in your red blood cells that attaches and transports oxygen molecules. Oximeters check these levels to determine saturation.

According to the American Thoracic Society, more than 89% of your blood should be oxygenated. Therefore, look for higher SpO2 readings.

  • The large reading will show Hemoglobin Saturation.
  • A smaller-sized reading will show pO2 levels.
  • You can also check the pulse rate in your oximeter.
