The purpose of this study was to self-management asthma including symptom, medication, and to prevent the exacerbation of the condition using the Personal Asthma Management System(PAMS) which was developed based on Personal digital Assistant(PDA).

A development tool of the PAMS was EVC(Microsoft Embadded Visual C++). The system contents referred to workshop report of the Global Initiative for Asthma, on-line lecture of the Korean Society of allergology and Korea Asthma allergy Foundation, asthma-related web-sites.

The PAMS was implemented with four main menus: personal information, symptom, medication management, and self care. The patients input their daily condition, and this data will be used in the successful prevention and management of asthma exacerbation. This real-time nature of PAMS is its primary advantage over other retrospective computing system for reducing the effects of forgetting, so this information will be useful in classifying of asthma severity.

The PAMS can be contributed to aid self-management of asthma and effective treatment by attending physician.
