Pulmonary Fiunction Test

Question 1

What does static lung function measure?

Answer 1

The maximal effort generated only at the beginning and end of the manoeuvre…….based on VOLUME not airflow

Question 2

What does dynamic lung function measure?

Answer 2

Lung volumes and it flow during forced inspiration or expiration OR. during breathing when maximal applied in applied throughout the respiratory manouvre

Question 3

FORCED EXPIRATORY VOLUME 1 FEV1

Answer 3

The volume of air exhaled in 1 second by a forced expiration after a full inspiration
* Reflects airflow
*Gauge if someone gas ASTHMA

Question 4

Forced Vital Capacity(FVC)

Answer 4

Inhale maximally live SVC but hard & fast at exhalation
Measures total air expired after maximal exhalation

Question 5

Forced Expiratory Ratio

Answer 5

FEV1/FVC …..Normal=75%
Increased/normal-indicates Restrictive Disorder eg muscular dystrophy,pulmonary fibrosis,sarcoidosis,obesity.
Decreased- Obstructive disorder eg COPD,asthma,cystic fibrosis.

Question 6

Obstructive respiratory disorders

Answer 6

Difficult to get air out of the lungs
Decreased FVC
Increased TLC,RV,FRC
Decreased FEF 25-75%

Question 7

RESTRICTIVE RESPIRATORY DISORDERS

Answer 7

Difficult to inspire
Decreased TLC,RV,FRC
Increased VC
