The heart rate monitor includes a user system that is close to the user's skin and communicates with the remote processing system.
When the heart rate monitor is operating, the medical staff pastes the heart rate sensor in the patient's chest and pastes the light-emitting diode indicator on the patient's cheek. When pasted, Heart Rate Monitor the heart rate sensor sends a signal to the light-emitting diode indicator immediately. If the heart rate is within normal range, the LEDs emit green light in each heartbeat of the heart, Heart Rate Monitor and if the heart rate is too high or too low, the LEDs glow red.
Heart rate monitors can improve the efficiency of health care workers. Because the light-emitting diode LED is clear, it will improve the safety of detection and avoid misdiagnosis.
Working principle of heart rate monitor
The combination of heart rate, a data that shows the intensity of the exercise, can more accurately measure the amount of calories a user burns per day. In addition, Heart Rate Monitor users can use the heart rate glance function to check their own heart rate situation anytime, anywhere. However, in addition to the features that these two users will use, the new supporting documentation details the technology behind the hardware, Heart Rate Monitor as well as some little-known software features. There are documents that measure your heart rate quietly in the background every 10 minutes. This data is stored in the iOS 8 health application for later viewing and integrates with third-party health tracking applications and hardware.
The "Photoelectric volume pulse wave method" was used to collect the heart rate data. Heart Rate Monitor This technique is based on a very simple truth: the blood is red because it can reflect red light and absorb the green. Therefore, the use of green LED lights with a photosensitive photodiode to detect any time flow through the blood of the wrist. When the user's heart beats, there will be more blood flow through the user's wrist, the amount of green light absorption will be greater. In the heart beats the gap, the blood flow reduces, causes the green light absorption also to reduce. By flashing the LEDs hundreds of times per second, you can calculate the number of beats per minute-that is, the heart rate.
