Smartwatches Measure Blood Oxygen Levels: How Reliable is it?

This new wearable technology indicator focuses on blood oxygen levels -- and it's going to change everything. Although complicated and seemingly meaningless, pulse oxygen levels indicate sleep apnea, which can help athletes recover.

We enter the realm of medical technology by discussing the measurement of blood oxygen levels, also known as Sp02.

Traditionally, the technique has been a device that clips onto your fingers, toes or even your earlobes. Although this method is simple, it does have some disadvantages because you need special equipment and most people overlook the importance of blood oxygen measurement.

During the second wave of COVID-19, delayed monitoring of blood oxygen levels and delayed hospitalization were the leading causes of death. So this could be a turning point for the smartwatch industry, but it's not just a turning point. People are concerned about blood oxygen levels, and a growing number of companies that make smartwatches are adding the feature to their products.

Simply put, pulse oxygen saturation measures the oxygen saturation, or oxygen level, in the blood. In medicine, oxygen may be the fifth vital sign to be checked because hypoxia can lead to death.

Considering the importance of this feature in smartwatches, BP has included it in all products. The smartwatch is a versatile wearable health device designed for everyday use. They can help you track your vital signs, track your steps, measure your calories, help with your daily activities, and access all your notifications faster.

Clinical diseases often lead to inadequate cellular oxygenation, which directly affects cellular metabolism and may even be life-threatening. Therefore, blood oxygen level testing is very important in medical investigation. In a bid to improve health without seeing a doctor, smartwatches deep in Rio de Janeiro offer a variety of health advantages. Of course, measuring blood oxygen is one of them.

With all this in mind, one might wonder: What is the smartwatch doing when it measures blood oxygen levels? Are Sp02 test results reliable? Before answering these questions, it's important to understand how a smartwatch measures blood oxygen levels.

Usually, the oximetry function on a smartwatch will give you an idea of your health based on the level of arterial oxygen saturation.

Oxygen saturation is the concentration of oxygen associated with hemoglobin in the blood. Using a smartwatch to measure blood oxygen is similar to acupuncture, except that the part of the body that is illuminated by light is the wrist.

When the smartwatch measures blood oxygen levels, red light reflected from subcutaneous tissue or bone is projected onto the body surface. Light is reflected from the subcutaneous tissue or bone to the smartwatch's sensors, which determine the difference between reflected and emitted light.

Blood oxygen readings can determine if a person needs a ventilator to help them breathe, can keep up with intense physical activity, or has breathing problems while sleeping. For these reasons, it's more convenient for smartwatches to have this feature.

One benefit of using a smartwatch for blood oxygen testing is that users can use the smartwatch for blood oxygen testing anytime, anywhere, without carrying additional medical equipment. You may find it difficult to carry a traditional pulse oximeter while hiking or at the office.

In general, SP02-induced blood oxygen levels above 95% are considered healthy and normal. It's time to see your doctor to see if your score is 92% or lower. Find out if there are any undetected health problems.

For example, in the case of sleep apnea, measuring blood oxygen levels can be very useful. If left untreated or tested, sleep apnea can lead to high blood pressure, obesity, and even heart attack.

Currently, the oximetry features on smartwatches aren't FDA or NMPA certified, meaning they aren't eligible to diagnose diseases. Consumer and medical products are held to different standards when it comes to accuracy. In terms of the performance of smartwatch measuring blood oxygen, although the accuracy has been improved, there is still a gap between it and medical level devices.
While smartwatches don't offer the same precision as professional medical devices, they are easier to access and more convenient for daily use. BP smartwatch is a comfortable, affordable and useful device that can monitor various elements of health from a single device.

While a smartwatch can't provide you with perfect, airtight measurements, it can give you enough information to know if you need to see a professional and if you need to increase the amount of oxygen in your blood. For example, BP can provide insights about your health that doctors can use to determine your treatment plan.

BP Smartwatches give insight into your sleep. Given its importance, you should pay attention to the amount and efficiency of your sleep. You need a good night's sleep to maintain your health and function throughout your life.

Another benefit of the BP smartwatch is smart alerts. It's a good idea to use it to remind you to drink more water, which is essential for your health. About 60 percent of an adult's body is water. Besides, we must consume enough water to survive. If you have trouble drinking water, bringing a water carrier may be your best option.

In addition to measuring blood oxygen levels, sleep tracking, smart reminders and other functions. BP smartwatch also offers more health and fitness features. Other examples include 24-hour heart rate monitoring, guided relaxation breathing, exercise-specific features, and more.

It may not be possible to get medical-grade blood oxygen level measurements from a smartwatch, but they do provide valuable insights into your health. You can use a smartwatch to monitor your general health and know when to go to the doctor and ask for precise and detailed tests.

Smartwatches aren't just a fashion accessory, they're a way to avoid missing notifications; They help you stay healthy. Of course, they can provide valuable insights about blood oxygen levels and vital signs, making them a good choice.
