Pulse oximeter review

Pulse oximeter (Pulse Oximeter) or blood oxygen meter is a device that can be used to measure the percentage of oxygen saturation of human arterial blood.

Pulse oximetry is a non-invasive method that measures and expresses the percentage of hemoglobin molecules that are fused with oxygen, with a normal rate of 95-97%.

This easy, painless measurement measures how oxygen is delivered to areas farther away from the heart, such as the arms and legs.

The device that performs this test is called a pulse oximeter.

Pulse oximeter is a small and lightweight device.

This non-invasive tool (without any needle inserting into the body tissue) is easily attached to the tip of the finger or thumb or earlobe.

 

When is a pulse oximeter used?

Pulse oximetry is used in the following cases:

During or after surgery or procedures that use sedatives.
To check if the patient needs a ventilator to help them breathe.
To see how lung drugs work.
To examine a person’s ability to achieve high levels of physical activity.
To check if a person suffers from respiratory failure during sleep (sleep apnea).
To diagnose all diseases that affect blood oxygen levels, such as heart attack, heart failure, chronic obstructive pulmonary disease (COPD), coronary heart disease (COVID-19), anemia, lung cancer, asthma, pneumonia and…
Blood oxygen saturation (SpO2)
SpO2 is an estimate of the amount of oxygen in the blood.
A saturation of 95% or more is usually considered a normal oxygen level.
However, a saturation rate of 92% or less (at sea level) indicates that the blood is low in saturated oxygen.
Insufficient saturation can cause a wide range of adverse health conditions, including chest pain, shortness of breath and increased heart rate.

 


What is hypoxemia?

Hypoxemia occurs when the level of oxygen in the blood is lower than normal.

If the blood oxygen level is too low, it may impair the function of the organs of the body.

The job of the blood is to supply oxygen to all the cells in the body to keep them healthy.

In hypoxemia, when blood oxygen levels are low, it can cause mild problems such as headaches and shortness of breath.

In severe cases, it can impair heart and brain function.

 

What are the causes of hypoxemia?

Many different problems may interfere with the transfer of natural oxygen levels to the blood.

Some of the most common causes of hypoxemia are:

Heart problems, including heart defects
Lung problems such as asthma and bronchitis
High altitude places, where the concentration of oxygen in the air is low.
Strong painkillers or other problems that slow down breathing.
Breathing disorder during sleep (sleep apnea)
Inflammation or ulceration of lung tissue (such as pulmonary fibrosis)

The symptoms of this disease also vary depending on the severity of the disease, which include: headache, shortness of breath, rapid heartbeat, cough, fatigue, confusion, pink skin, nails and lips.

 

How does a pulse oximeter work?

The pulse oximeter passes a beam of red and infrared light through a blood capillary.

The ratio of red to infrared light indicates the amount of oxygen saturation in the blood.

The Kentuck pulse oximeter works on the principle that oxygenated blood is lighter red than less oxygenated blood, which is blue-purple.

First, the oximeter measures the sum of the intensities of both red colors, indicating blood clots with and without oxygen.

The oximeter detects the pulse and then subtracts the intensity of the detected color when there is no pulse.

The remaining intensity of the dye indicates only oxygenated red blood.

This value is displayed on the electronic screen as a percentage of blood oxygen saturation.
