How to measure your pulse at home? Most prefer to use either a smartwatch or, at worst, a fitness bracelet for this. These devices are actually quite accurate, but they require a certain cost to acquire them. Moreover, the higher the class of the device, the higher the price will be. If any Xiaomi Mi Band can be bought for only 2-3 thousand, then Apple Watch will cost you at least 10 times more. But, if your goal is heart rate measurement and some other indicators, there is no need to spend so much. You can just use the iPhone app.
In the application Google Fit, which is analogous to “Health” from Apple, there are functions heart rate and respiratory rate measurements (NPV). They do not require external equipment and allow you to take all the necessary measurements using only your iPhone’s cameras. Looking ahead, I will say that the measurements are quite accurate, so they can be trusted.
How to measure heart rate on iPhone
For heart rate measurements Google Fit uses the main camera of the smartphone. You just need to put your finger on it and wait for the algorithms to complete the calculations. But before that you need to activate the necessary parameters:
- Download Google Fit yourself on iPhone and launch;
- Go to “Overview” – “Vitality”;
- Open “How to measure heart rate” and give the application access to the camera;
- Place your finger on the main camera with light pressure;
- Wait until the end of the heart rate measurements and, if necessary, save.
Important clarification: If this is your first time launching Google Fit, you may not find your heart rate cards. In this case, simply unload the application from the multitasking menu, and then start it again – all the necessary parameters should appear.
It is not surprising that the app measures your heart rateusing the camera for this. This is completely standard practice. The fact is that at the moment of contraction of the heart muscle (we call it a stroke), it throws out a portion of blood saturated with oxygen, which has a darker shade. The camera captures these emissions and repels them in its measurements. Therefore, it is important to press your finger firmly against the lens. But don’t overdo it.
How to measure your breathing rate
Respiratory rate – This is a completely different indicator, which has only an indirect relationship to the pulse. In simple terms, it shows how many breaths you take per minute. It would seem, what does it matter at all? But in fact, NPV is an important indicator that doctors record along with the pulse at each appointment.
To measure NPV, you need to do the following:
- Open the Google Fit app on your iPhone;
- Go to “Overview” – “Vitality”;
- Open the “Measure breathing rate” tab;
- Sit as shown in the instructions on the screen;
- Wait until the end of the measurements and save if necessary.
Normally, a person takes 16-20 breaths per minute. In a dream, this indicator decreases to 12-14, and with physical, emotional stress or after an abundant intake of food, it naturally increases. Deviation from the norm, although not always, is still most often a sign of some kind of pathology. For example, a too high rate of NPV may be a sign of narrowing of the lumen in the bronchi, pneumonia, pleurisy, rib fracture, etc. A reduced breathing may be due to increased intracranial pressure.
Naturally, Google Fit is not a medical app and even Google itself does not recommend trusting it 100%. However, in this case, this is most likely just a disclaimer, because practice shows that the application quite accurately measures both heart rate and respiratory rate. Daily measurement of these indicators will help to control your health at least at a basic level, so that, if something happens, you can see a doctor.
