INTRODUCTION

The function of lung is for gas exchange

Respiration is to allow oxygen to move

from the air into the venous blood and

carbon dioxide to move out

RESPIRATION

Ventilation

Diffusion

Perfusion

Page 6: Dasar Faal Paru

VENTILATION

Lung volume

Static lung volume

Dynamic lung volumeSpirometry

Page 7: Dasar Faal Paru

SPIROMETRY

( To Spir = Bernapas )

Page 8: Dasar Faal Paru

SPIROMETRY

Measurement of Lung volume

Simple

Easy to perform

Reliable

Page 9: Dasar Faal Paru

SPIROMETRY

Sensitive

Accurate

Reproducible

Page 10: Dasar Faal Paru

SPIROMETRY

ATS recommendation :

3 acceptable

2 reproducible

Maximal 8 maneuver

Page 11: Dasar Faal Paru

SPIROMETRY

Good preparation

Good maneuver

Accurate result

Garbage in – garbage out

LUNG FUNCTION TEST

1. To establish diagnosis

Page 21: Dasar Faal Paru

LUNG FUNCTION TEST

2. To evaluate treatment

Page 22: Dasar Faal Paru

LUNG FUNCTION TEST

3. To monitor the nature of disease

Page 23: Dasar Faal Paru

LUNG FUNCTION TEST

4. To determine the degree of disability

Page 24: Dasar Faal Paru

CONCLUSION

Lung function test give information

about the disease Spirometry is a simple method to

measure ventilation Good preparation and good maneuver

is important Serial measurement is necessary
