Abstract:
The peak flow meter is suggested by WHO and GINA for daily use by asthma patients in order to monitor symptoms and manage exacerbations. Even though the peak flow meter is compact, affordable, and portable, it only provides PEFR information. In comparison, the spirometer delivers more thorough lung information. However, it is expensive and difficult to carry, especially the conventional spirometer used in hospitals. The patient must visit the hospital to use it. This research aims to study the functionalities requires for developing the portable spirometer, targeted user and acceptable price in Thai market. Users place a high value on hygiene; hence, the device must be easily detachable in order to replace or clean its components. The portable spirometer should not cost more than 1,000 Thai Baht. With a device that is easily portable and monitors with the same accuracy as a spirometer, the patient may carry it without burden or difficulty. This will allow patients to check their lung function regularly. As a result of having complete information, the doctor will be able to effectively monitor the patient's status and alter the treatment. The size and market trend of this lung monitoring device comprises a worldwide market with a large number of respiratory patients. However, knowledge of lung monitoring devices is minimal on the Thai market. The significance of spirometry should be conveyed to the users.
