Question: Explain the discrepancies in the results obtained, compare the results of the healthy lung to those of a diseased lung and give a possible disease that this could be of.

Aim

The aim of this experiment is to:

Evaluate lung volumes and capacities using a spirometer and analyse the obtained data.
Calculate and comprehend the forced expiratory vital capacity.
Contrast your pulmonary function test findings with those of a standard individual and an individual afflicted with obstructive lung disease.
Present your experiment outcomes in a scientific and organized fashion.

Introduction

The process of gas exchange in the lungs happens within small structures called alveoli, where the pulmonary blood interacts with the air. The effectiveness of this gas exchange relies on the process of ventilation, which involves rhythmic breathing movements. These breathing movements facilitate the movement of air into and out of the alveoli. During inhalation, fresh atmosphere air enters the alveoli, while during exhalation, some of the stagnant air with lower oxygen and higher carbon dioxide levels is expelled.

Spirometry is a technique employed to gauge the amount of air entering and exiting the lungs with every breath. Its significant is growing considering the global surge in respiratory ailments. Spirometry stands out as the most appropriate approach for swiftly and dependably assessing individuals who might be at risk of obstructive pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD) and asthma, as well as restrictive lung disease such as tuberculosis. It's worth noting that a significant portion of COPD instances can be prevented, with tobacco smoking being the leading cause of most cases (Fourie, 2021).
