Breathing rate monitor is a device used to measure breathing rate.
The following are some use cases for the device:
-For medical purposes, such as monitoring the respiratory status of an individual with neuromuscular weakness or potential decrease in pulmonary function due to surgery, lung disease, pneumothorax, central nervous system damage and more.
-For sports and wellness, such as athletes monitoring their respiratory status to avoid fatigue and decrease in performance.
All breathing rate monitors operate on the same basic principle: flow measurement. A sensor is used to detect flow of air through the device and a microcontroller records this data and calculates the breathing rate based on it. This general set up is used in a variety of different types of breathing rate monitors.
The most common type of flow sensor used is a pitot tube. This sensor uses the Bernoulli principle to measure the airflow. When air flows over the hole on the top of the tube, it creates a low pressure area and this causes the air to speed up. This increase in speed is detected by the sensor and it calculates the breathing rate based on this data.
There are also other types of sensors that can be used, such as an optical sensor or a hot wire anemometer. An optical sensor uses a light and a photo diode to detect changes in light levels. This change is caused by the displacement of the air column as it moves through the sensor. A hot wire anemometer uses warm wires to detect airflow. When this tungsten filament is moved by the air, it causes a change in resistance which is detected by the microcontroller.
Another type of breathing rate monitor is one that measures temperature difference between inhaled and exhaled air. This type of sensor measures the difference in temperature between exhaled and inhaled air which is caused by the body’s energy expenditure when breathing. This method is more accurate than measuring airflow because it does not rely on that changes in airflow, such as those caused by abdominal movement, to calculate breathing rate.
A less common type of respiratory monitor is an impedance pneumography monitor. This type of monitor measures the resistance offered by the respiratory muscles when they contract. This information is used to calculate the breathing rate.
The data collected by the breathing rate monitor can be displayed in a number of ways, such as on a screen or computer, or can be stored in a file for later analysis. It can also be used to trigger other devices or systems, such as sound an alarm when the breathing rate is too high. This type of monitor is most commonly used in hospitals and clinics but can also be found as a home device for those with respiratory problems or those who wish to live healthier lifestyles.
