When it comes to accuracy, it is important to consider both the oximeter and the Apple Watch. The oximeter is typically more accurate due to its design and because it is designed to measure the specific concentration of oxygen in the blood.
The oximeter measures the oxygen levels in the blood by inserting a sensor into a finger. This method is more accurate than the Apple Watch.
On the other hand, the Apple Watch measures heart rate, respiratory rate and blood oxygen levels through a sensor on the backside of the watch. The Apple Watch is a convenient way to measure some important health metrics, but due to its design, the measurements may not be as accurate as those measured by an oximeter.
Overall, depending on the specific task, an oximeter is often considered to be more accurate than the Apple Watch. However, the convenience of the Apple Watch is sometimes worth the difference in accuracy.

Is Apple Watch as accurate as a pulse oximeter?
No, the Apple Watch is not as accurate as a pulse oximeter. While the Apple Watch does measure “pulse rate” with its optical heart rate sensor, the accuracy of this measurement is not comparable to a pulse oximeter.
Pulse oximeters are used to directly measure the oxygen saturation of the bloodstream and measure the pulse by using painless transmittance of red and infrared light to the patient’s finger, allowing for a more accurate measurement.
In comparison, the Apple Watch uses green LED lights to measure the amount of blood returning through the wrist, which is less accurate.
Can I use Apple Watch as oximeter?
No, you cannot use an Apple Watch as an oximeter. An oximeter is a medical device that measures the amount of oxygen in a person’s blood. It does so by measuring the amount of light that blood absorbs when illuminated with a specific wavelength.
Apple Watches do not have the necessary hardware to measure oxygen, meaning they are unable to use this technology. That said, Apple has recently announced they will be adding new features to the watch which will integrate the Health app with providers that offer oximetry services.
However, even with this integration, it will not be possible to use the watch as an oximeter itself.
Is Pulse Oximeter same as Blood Oxygen?
No, a pulse oximeter is not the same as blood oxygen. Pulse oximeters measure the percentage of oxygen being carried in the hemoglobin, not simply oxygen saturation in the blood itself. Pulse oximetry is used to measure the amount of oxygen being transported through the body from the lungs to the rest of the body.
It uses an infrared light to measure the absorbance of light by oxygenated hemoglobin and deoxygenated hemoglobin in the blood. By calculating the ratio of oxygenated to deoxygenated blood, the device can measure the saturation of oxygen in the blood (SaO2).
This value can be compared to the normal range of saturation of oxygen found in the blood to determine if a patient’s oxygen levels need to be addressed. Blood oxygen, on the other hand, is the amount of oxygenated hemoglobin in the blood, which is a direct measurement of the oxygen content in the blood.
This is generally measured with a laboratory test known as an arterial blood gas (ABG) or a venous blood gas (VBG).
How accurate is Apple Watch respiratory rate?
Apple Watch’s respiratory rate monitoring capabilities have been tested empirically and have shown to be quite accurate. In a study conducted by Stanford University, it was found that the Apple Watch was able to accurately measure respiratory rate as low as 8 breaths per minute, with an overall error rate of 0.
25 breaths per minute. Additionally, the Apple Watch was able to detect changes in a person’s respiratory rate when there was a statistically significant difference in their breathing pattern. This suggests that the Apple Watch is able to provide an accurate measurement of respiratory rate.
The accuracy of the Apple Watch’s respiratory rate monitoring accuracy can vary and depend on many factors, such as how tightly the watch is worn, the size of the user’s chest, and how active the user is.
In addition, some studies have found that the Apple Watch may overestimate respiratory rate when a person is talking or singing. Thus, it is important to be mindful of these potential sources of error and consider taking additional measurements if needed.
The accuracy and precision of the Apple Watch’s respiratory rate can be further improved by adjusting its settings. The Apple Watch comes with a feature called “Adjust Respiratory rate” which allows the user to input their own breathing rate and the watch will automatically adjust its reading accordingly.
This can be useful for runners or people who move around a lot, as the watch will be more likely to capture their actual respiratory rate. Ultimately, the accuracy of the Apple Watch’s respiratory rate monitoring capabilities is quite reliable, and it may be a beneficial tool to use if you want to track your breathing rate more accurately and in more detail.
Can Apple Watch detect lung problems?
No, the Apple Watch cannot detect lung problems by itself. However, the Apple Watch can be used to monitor certain health conditions. For example, there are apps available for the Apple Watch that can monitor heart rate, oxygen levels, and other information that can help doctors detect irregularities and warning signs to help diagnose lung problems.
Additionally, some of these apps can also be used to measure other vital signs such as temperature, breathing rate and breathing capacity. If any irregularities are detected, users can take that data to their doctor who can use it to better understand and diagnose any potential lung problems.
Can an Apple Watch tell if you have sleep apnea?
No, unfortunately an Apple Watch alone cannot tell if you have sleep apnea. Although it does track your physical activities throughout the day, and can monitor your sleeping patterns, it does not measure breathing.
Therefore it is unable to detect signs of sleep apnea, which is characterised by abnormal or shallow/interrupted breathing during sleep.
If you think you may have sleep apnea, it is important to speak with your doctor and seek a diagnosis. Typically, in order to diagnose sleep apnea, a sleep study is conducted to look for signs of abnormal breathing or other disruptions during sleep.
Furthermore, other tests might be conducted to measure oxygen levels during sleep. Both of these tests are important to determine if you have sleep apnea and what type, as it is a serious medical condition.
The good news is that an Apple Watch can still be an important tool in helping you manage and track your sleep apnea treatment. If your doctor has already diagnosed you with sleep apnea, the watch can sync with a CPAP (Continuous Positive Airway Pressure) machine or other biometric information that can be used to track your respiration, pulse, temperature, and other data to monitor your sleep.
What should my respiratory rate be while sleeping?
Your respiratory rate while sleeping should generally be between 12 and 20 breaths per minute. This is a normal range for healthy adults and can vary depending on age, activity level, and other factors.
Generally, the rate will decrease during sleep, as your breathing becomes slower and deeper. It can also be affected by the position you sleep in and any underlying medical conditions or sleep disorders you may have.
If you find your respiratory rate while sleeping is consistently higher than 20 breaths per minute, it could be a sign of sleep apnea or other medical condition, and it’s best to consult your doctor.
What triggers Apple Watch to tell you to breathe?
The Apple Watch has a Breathe app that notifies its wearer to pause for a few minutes and focus on their breathing. This serves as a reminder for the wearer to be mindful and reduce stress. When active, Breathe sends notifications to its wearer at preset intervals (which can be customized in the Watch Settings), gently tapping the wrist as a notification.
This reminder remains active whether the user is toggling between apps or receiving a call. It has a simple design, offering a single deep-breathing animation which steadily expands and contracts the circle on the screen in coordination with the user’s breathing rhythm.
By tapping the screen when the circles reach their maximum size, users can start the breathing animation and use it to regulate their breathing session. The calming animation and haptic feedback serve as visual and tactile reminders to take a moment to pause, take a deep breath, and relax.
