What is a Pulse Oximeter
A pulse oximeter measures the oxygen saturation levels in a person’s blood. It is a device that has a clip-like design that can be attached to a body part such as a finger or a toe. It then gives a reading of the oxygen levels in the blood, giving an indication of how well the heart is providing oxygen to that part of the body.
Pulse Oximeters are beneficial in a lot of ways. From monitoring blood oxygen levels of people with serious diseases to helping people sleep and breathe better, they find use in a lot of health-related treatments. Some of the common diseases that require a constant eye on oxygen saturation levels include:
- Lung diseases
- Heart problems
- COPD – Chronic Obstructive Pulmonary Disease
How does a Pulse Oximeter Work?
A pulse oximeter cannot by itself detect the level of oxygen in the blood. It uses light absorption to mathematically calculate that level to a reliable degree of accuracy. Once an oximeter is clamped on to a finger or a toe, or any other body part for that matter, it passes a beam of light through the body and detects that beam on the other side of the oximeter with the help of a sensor. By measuring the intensity of the light that reaches the sensor after passing through the body, it can determine the levels of light absorption and use them to mathematically calculate the level of oxygen in the blood that the light has passed through.
Benefits and Limitations of a Pulse Oximeter
Benefits of a Pulse Oximeter
Here are some of the benefits of pulse oximeters:
- Specially designed oximeters are used in newborn intensive care, alerting the staff on any abnormalities in the newborn’s blood oxygen level.
- Oximeters provide psychological relief to people with heart or respiratory problems by alerting them on changes in oxygen levels
- When people are put under anesthesia, pulse oximeters are employed to constantly monitor their oxygen saturation.
- They are vital in assessing the impact on lung medication
- They help in measuring whether a ventilator is helpful or not
- Since physical activity has an impact on oxygen saturation levels, oximeters help determine how much increase in physical activity can be tolerated by a person.
- They are used for patients suffering from sleep apnea – to determine if the patient stops breathing in his sleep at any point during the night.
Limitations of a Pulse Oximeter
There are a few limitations associated with pulse oximeters, which are important for the users to know.
- Cases of carbon monoxide poisoning cannot be detected by a pulse oximeter.
- Changes in the user’s pulse can reduce the accuracy of the reading.
- Outside interference of light, or using nail polish can alter the meter’s accuracy.
- Poor blood circulation or cold hands can give an unreliable oxygen saturation level reading.
The Four Best Method
What We Do . . .
We started Four Best on the premise that a great deal of the information required to properly evaluate a given product is already right in front of your (and our) eyes. In fact there is too much information! A crucial skill necessary to picking the best products is instead the ability to cull through the available information, focusing on what should really drive a purchase decision.
To make those crucial determinations as to what matters and what doesn’t, we begin by thinking through what really matters to us when we use a particular product. We then use the that type of product to further refine the features we care about and that we think you will care about too. Next we search the web, looking to manufacturer’s websites, product specifications, consumer reports, expert blogs, research reports and the like to obtain crucial insights and the facts.
Finally, we distill the results of our research and combine it with our own experiences as consumers, professionals, techies, mothers, fathers, hobbyists, designers, software engineers, attorneys (sorry) and more. Ultimately, this process results in the reviews we present to you. We hope you enjoy!
