DESIGN OF LUNG VOLUME MEASURING Tools Using Pressure Sensors To Recognize Lung Abnormalities

Design of Lung Volume Measuring Tools using Pressure Sensors to Recognize Lung Abnormalities

The design of a tool to measure the volume of the lungs is a crucial aspect of lung health checks. With the increasing prevalence of respiratory diseases, it is essential to have accurate and reliable methods for assessing lung function. In this article, we will discuss the design of a lung volume measuring instrument using a pressure sensor to recognize lung abnormalities.

The Importance of Lung Volume Measurement

Lung volume measurement is a critical aspect of lung health checks. It helps to assess the capacity of the lungs to expand and contract, which is essential for proper breathing. The measurement of lung volume can also help to identify abnormalities in lung function, such as those caused by respiratory diseases. With the increasing prevalence of respiratory diseases, it is essential to have accurate and reliable methods for assessing lung function.

Design of the Lung Volume Measuring Instrument

The design of the lung volume measuring instrument involves the use of a pressure sensor to measure the flow of air in and out of the lungs. The instrument consists of a MPX10DP pressure sensor, an Analog Digital Converter (ADC), and an Arduino Pro Mini microcontroller. The MPX10DP pressure sensor is used to measure the pressure of the air in the lungs, while the ADC is used to convert the analog signal from the pressure sensor into a digital signal. The Arduino Pro Mini microcontroller is used to process the digital signal and estimate the sensor conditions that may be influenced by disturbances.

Working Principle of the Instrument

The working principle of the instrument is similar to a peak flow meter commonly used in lung health checks. The instrument measures the flow of air in and out of the lungs by detecting the pressure changes in the lungs. The data obtained from the instrument is then displayed on a PC and further processed to produce a graph that reflects the volume of the lungs based on the relationship between discharge and time.

Analysis of Measurement Results

In the testing conducted, the ratio between the measurement results of the tool designed with a peak flow meter shows an error value of 46.66%. Nevertheless, this tool can still provide significant information, especially in reading respondents' breathing. Through the data obtained, it appears that respondents who do not smoke have maximum breathing speed that lasts longer compared to respondents who smoke.

Limitations of the Instrument

However, this tool has limitations that do not show a clear difference between the volume of the lungs of smokers and non-smokers when using the MPX10DP pressure sensor. This indicates that although this tool can function as an indicator of lung disorders, further development is needed in order to be able to distinguish more clearly between the two groups.

Overall, the design of this lung volume measuring instrument makes an important contribution in the field of lung health. With simpler technology and more affordable costs, this tool has the potential to be used in initial examination of lung health, especially in areas with limited access to more sophisticated health services. Efforts to develop and further research are needed to increase the accuracy and ability of this tool in detecting more specific lung conditions, so that it can provide greater benefits for its users.

Future directions for the development of this tool include:

• Improving the accuracy of the instrument: Further research is needed to improve the accuracy of the instrument in detecting lung abnormalities.
• Developing a more sophisticated algorithm: A more sophisticated algorithm is needed to distinguish between the volume of the lungs of smokers and non-smokers.
• Increasing the sensitivity of the instrument: The instrument needs to be more sensitive to detect small changes in lung function.
• Reducing the cost of the instrument: The cost of the instrument needs to be reduced to make it more accessible to people in areas with limited access to health services.

In conclusion, the design of a lung volume measuring instrument using a pressure sensor is a crucial aspect of lung health checks. With the increasing prevalence of respiratory diseases, it is essential to have accurate and reliable methods for assessing lung function. The instrument designed in this study has the potential to be used in initial examination of lung health, especially in areas with limited access to more sophisticated health services. However, further development is needed to increase the accuracy and ability of this tool in detecting more specific lung conditions.
