Chapter I - The Problem and its Background

Background of the Study

Every individual varies. Each respires from different walks of life. Towards a particular something all minds are set. Distinct destinations. Distinct concerns. But what is such concern that proclaims itself as top?


Each and every single someone aims to have the best of their years. But as individuals go on from one genre to another, illness and all of its sorts seem to progress and cope with how fast people move along. Health is wealth. A fact which turns to become more literal these days. In a world where everything is at a given price, health is indeed highly priced.

The researchers aim to focus on one common but very crucial health wise concern, a chronic lung disorder marked by recurring episodes of airway obstruction: Asthma. One neglected sickness mostly of the rural population as it requires costly medicines and apparatus, or worst such treatments are unavailable.

Statement of the Problem

Recent surveys show that asthma is causing unnecessary suffering. One person dies every hour from an asthma attack. A survey released on World Asthma Day (May 2nd 2006) reveals that people see asthma as frightening, debilitating, and uncontrollable.

No matter what their symptoms many of the 300 million asthma sufferers in the world are desperate for relief from asthma.

There is a way to take charge of asthma.One effective method of which is through the help of Nebulizers (electrically powered machine that turns liquid medication into a mist so that it can be breathed directly into the lungs through a face mask or mouthpiece).

The proposal shall be specific on this common machine. Atomizers, oxygen/air pump and inhalers being its supplement. The researchers intend to produce a very economical and efficient device for the cure of asthma. Basic principles of which shall be gathered from Electronics, Digital and Analog Circuits, Microcontrollers and Thermodynamics.

Objectives of the Study

General Objectives

The main objective of this research study is to construct a modified but effective nebulizer.

Specific Objectives

➢ To produce a more economical medical apparatus for the respiratory illness, asthma.

➢ To make a precise timing device attached to the apparatus.

Significance of the Study

This research study proposes to extend medical assistance to individuals with respiratory illness. Efficient output shall then give huge contribution in innovating Computer Technology and Medicine.

Immediate beneficiary being the College of Engineering, Polytechnic University of the Philippines, Manila.

Scope and Limitations of the Study

➢ The machine will be automatically operated, thus making it simpler, reliable, more effective and cheaper.

➢ The machine is intended for indoor and outdoor purposes, having spare batteries (rechargeable) for emergency usage.

➢ The machine aims to be potent and carry less risk of side effects.

➢ The research study intends to have a better contribute in the field of medicine.

Definition of Terms

Nebulizer - A is an electrically powered machine that turns liquid medication into a mist so that it can be breathed directly into the lungs through a face mask or mouthpiece

Nebulization – is a process to convert a solution into a suspension of a particle size that can be inhaled into the lower respiratory tract.

Asthma - a chronic illness involving the respiratory system in which the airway occasionally constricts, becomes inflamed, and is lined with excessive amounts of mucus, often...
