I can conclude from my results that males have larger FEV1 and FVC average values than females, which shows that males have on average larger diameter around the chest and hence they have larger lungs than females.

Introduction

Spirometry Introduction Spirometry is a measurement of lung function. It measures the volume and flow of air that is inhaled and exhaled. Spirometry is a tool used to measure lung diseases such as asthma, cystic fibrosis and chronic obstructive pulmonary disease (COPD). A spirometry test is performed using a toll called spirometer and is used to diagnose various lung conditions and also to monitor the severity of certain lung conditions and their response to treatment. Spirometry is amore accurate test than peak flow meter for diagnosis and monitoring people with COPD. Spirometry mainly measures: * Forced expiratory volume in one second (FEV1) - this is the amount of air a person blows out in one second. * Forced vital capacity (FVC) - this is the total amount of air a person blows out in one breath. Both measurements are measured in litres (L). Spirometry is a low risk test. However a person blowing out very hard can increase the pressure in the chest, abdomen and eye. ...read more.

My actual results show that I have much lower results than predicted. The percentage predicted clearly shows that I am at a risk of having a lung disease as the percentage predicted for FVC and FEV1 are below 80%. ...read more.

Conclusion

All this indicates that males have larger lung capacity and therefore can breathe out fully faster and longer. For people who have COPD, FEV1 is used to determine the severity of the disease, "with less than 70% considered mild and less than 35% considered severe"1. Therefore spirometer is a great tool used to detect the severity of COPD in a patient, and so through the results obtained, it allows the doctor to give the patient the right treatments. Conclusion I can conclude from my results that males have larger FEV1 and FVC average values than females, which shows that males have on average larger diameter around the chest and hence they have larger lungs than females. I believe that my results are not very accurate as only one result was obtained per person, due to the lack of time. A good result would need to have at least three readings for a more precise conclusion of the person's health and whether he or she has any disease or not.
