Pulse Oximeter – Definition, Guide, How it works, Top Brands, Prices and Reviews


The pulse oximeter is a device used for checking the oxygen saturation in a person. The reading of the peripheral oxygen saturation may not be identical to that of arterial oxygen saturation. A pulse oximeter is a commonly used transmissivity application mode. It is a sensor device that can be placed on a thin part of the patient’s body, i.e., earlobe or fingertip, mostly in the case of children.

What is Pulse Oximeter and How It Works?

It is a medical device that indirectly monitors oxygen saturation in the human body in the blood and used for detecting the changes in the skin for blood volume. By calculating these aspects, it produces a photoplethysmogram which incorporates in the multi-parameter monitor. The device can pass two significant wavelengths of light through the body to the detector that measures the changing absorbance of the same. Thus the changes in wavelength help in determining the absorbance. This apparatus can be useful in people with COPD, congestive heart failure, and asthma. While determining the changes in absorbance, certain factors are excluded such as muscle, fat, venous blood and enamel coatings [1].

How does Pulse Oximeter Work?

The finger pulse oximeter can work by passing the light through the finger where thepulse oximeter sensorcan detect the oxygen in the blood. It is done depending on the light passed through the finger where the inbuilt technology can help in calculating the results by displaying the same on the oximeter screen.

Thoughpulse oximetryis used for monitoring the oxygen levels, it cannot determine the amount of oxygen metabolized. Therefore it is essential to measure the carbon dioxide levels for detecting the abnormalities in the ventilation. It cannot identify the hypoventilation in a patient by using the supplemented oxygen. It can efficiently work, only if the patient can breathe from room air. In this process, the abnormalities which take place in respiratory function can be detected under such circumstances. The regular administration of supplemental oxygen is not essential if, the patient can manage the oxygenation in room air. If this continues, it can result in hypoventilation that can be undetected [2].

How to Use Pulse Oximeter?

It is effortless to use a pulse oximeter as it is a simple device which can be clipped to the finger. Thepulse oximeter readingsare recorded and depending on which the oxygen supply can be regulated. There is variouspulse oximeter usesas they are widely used in various walks of life.

  • The pulse oximeter is used for expanding the level of activities by measuring the oxygen saturation levels at any point in time. This can be used conveniently at work, home or during relaxing.
  • The pulse oximeter can tolerate various activities and manages the oxygen usage, manages COPD.
  • It helps in regulating the oxygen saturation during mountain climbing or playing sports. It is most widely used in people living in high altitudes who can determine the oxygen saturation levels frequently.
  • A medical practitioner can suggest the specific oxygen saturation targets for their patients. The regular flow rate should be kept under control for maintaining the appropriate oxygen saturation at the prescribed levels. In most of the cases, oxygen saturation of more than 90% is expected in all kinds of activities.
  • Pulmonary rehabilitation can be possible for the patient as it is considered as standard care for patients. It helps in improving the tolerance and reduces the span of breath which helps in expanding the horizons.
  • The pulse oximeter can be helpful in managing clinical conditions like asthma, anemia, chronic obstructive pulmonary disease, pneumonia, heart issues wherepulse oximeter CVS is used.

How to Read Pulse Oximeter Readings?

A pulse oximeter helps in determining the peripheral capillary oxygen saturation that is an essential factor for a healthy person. An average person should be having the peripheral capillary oxygen saturation of 95-99%. In the case of mild respiratory disease it can be 90% or more, and if it falls below 90%, it can lead to emergency situations [3].

The pulse rate and blood oxygen levels are an indicator of good health which again depends on an average pulse rate. Pulse rate can vary depending on the age of a person where a baby can have a pulse rate of 115 beats whereas a person of good health can be having 95. The variations in pulse rates depend on an exercise regimen, diet, and climatic conditions.

The blood oxygen levels rely on the respiration rate, day to day activities and oxygen in the air. The pulse oximeter, therefore, records the readings as per the body conditions. These readings are recorded, and oxygen supply or requirements are decided based on the same. Thus in various surgeries and medical circumstances, it is mandatory to use a pulse oximeter.

Top Brands and Prices of Pulse Oximeters

There is the availability of pulse oximeter at Amazon for clinical use in competitive prices of various brands. They are mostly used in hospitals during surgeries and post-surgical conditions for tracking the oxygen supply. In some cases, pulse oximeters are used to determine the oxygen supply at home in patients suffering from COPD, asthma and heart diseases. The pulse oximeters at Amazon need to be purchased based on the reviews of people who have already used.
