How blood pressure applications work
The operation of blood pressure measurement applications is based on the use of cameras and touch sensors present on mobile devices. These sensors can measure variations in blood pressure through changes in light intensity, which are captured by the camera when a finger is placed on it. The app then processes this information and displays your blood pressure on the screen.
It is important to note that, although these applications can offer fairly accurate results, they should not replace consultation with a medical professional or the use of approved blood pressure monitors. Instead, they can serve as an additional monitoring tool to track our cardiovascular health.
Selection of free and accurate applications
There are several free and easily accessible applications available for both Android and iOS devices. Below is a list of some of the most notable and precise:
- Instant Heart Rate: This application allows you to measure both heart rate and blood pressure, providing a complete experience for the user.
- Blood Pressure Monitor: With a specific focus on blood pressure measurement, this app is very easy to use and offers accurate results.
- Cardiio: Like Instant Heart Rate, Cardiio also allows you to measure heart rate and blood pressure, providing a complete solution for monitoring our cardiovascular health.
Correct use of applications
To ensure accurate results when using these applications, it is essential to follow certain guidelines and precautions in their use. First of all, we must place our index finger on the camera and flash of the mobile device. It is important to apply moderate and constant pressure so that the camera can adequately detect variations in light intensity.
It is advisable to measure our blood pressure in a quiet environment, without noise or sudden movements, as these can affect the results obtained. Furthermore, it is advisable to repeat the process at least three times and calculate the average of the values obtained, to ensure a more accurate and reliable measurement.
Pros and cons of using blood pressure apps
Pros:
- Ease of Access: The applications are available for free download and can be used anytime, anywhere.
- Accuracy: If used correctly, these applications can provide accurate and useful results for tracking our blood pressure.
- Convenience: They allow blood pressure to be measured without the need to use additional medical devices, making them a practical and comfortable tool.
Cons:
- They do not replace medical consultation: Despite their advantages, the applications should not be used as a substitute for consultation with a health professional or the use of approved blood pressure monitors.
- Reliability: The reliability of these systems depends on the quality of the camera and sensors of the mobile device, as well as correct use by the user.
Closing remarks
Free and accurate blood pressure measurement applications can be an excellent tool to complement the control of our cardiovascular health. However, it is crucial to use them appropriately and not depend exclusively on them to evaluate our state of health. Going to regular medical consultations and following the recommendations of professionals is essential to maintain good cardiovascular health and prevent possible complications.
