COUPLED MOBILE PHONE PLATFORM WITH PEAK FLOW METER ENABLES REAL-TIME LUNG FUNCTION ASSESSMENT

ABSTRACT

Asthma is a chronic disease and a growing health problem worldwide. The objective of this pilot study was to test the feasibility and utilization of tracking asthma symptoms through an innovative mobile phone application. Providing health care. It is therefore important to develop accurate devices to monitor the disease symptoms so doctors can take appropriate steps to treat the patient with proper medication. One effective way to track asthma symptoms is to monitor a patient’s peak expiratory flow (PEF).

There are presently many different handheld PEF monitors commercially available, and these suffer from a variety of different limitations. Many current PEF meters are inaccurate, inconvenient to use, bulky, expensive, and rarely include real-time data plotting capabilities.

We have created a user-friendly, accurate, and moderately inexpensive external mobile device accessory that records and stores the user’s PEF, and graphs this data over time. We also have created a custom software interface to forward this stored data electronically. E-mail forwarding and “telemedicine” capabilities will give physicians a better way to monitor the patient’s PEF over time, leading to a more convenient method for physicians to make appropriate changes in patient medication regimens.

Existing System

·  Traditional methods of monitoring, such as manual asthma diaries, have not been very successful largely because these methods require more effort and commitment than most patients can easily devote.

·  The efficacy of an asthma monitoring plan using PEF decreases, however, when patients deviate from their prescribed medical action plan or fail to follow the plan entirely.

Disadvantage

·  Device accuracy must be checked first by comparing to a mercury device, then during measurement on the user.

·  The most accurate devices don't give accurate readings on certain individuals.

·  Body movements may influence accuracy.

Proposed System

·  A novel approach to simplify the data collection and sharing process was investigated to create a convenient, accurate, and portable PEF device that enables patients to use the device in any setting.

·  This paper outlines the sensor development and instrumentation steps required to enable real-time collection of PEF data from patients onto mobile phone or computing devices.

Advantages

·  Design and Construction of the Peak Expiratory Flow(PEF) Sensor and

Package Enclosure.

·  Custom Electronic Interface Joining Mobile Device to PEF Sensor.

·  Utilization of the Bluetooth as a Data Acquisition Port and Software Program.
