i. T1RF
ii. T2RF
A
i. pO2 = low, pCO2 = low/normal
there is 1 change
ii. pO2 = low, pCO2 = high
2 changes
2
Q

A
Pulmonary embolism
3
Q

A
hypoventilation
4
Q

5
Q
What are causes of obstructive respiratory diseasE?
A
Asthma - variable airflow obstruction, reversible
COPD - fixed obstruction
Bronchiectasis
6
Q
What LFT results indicate obstructive respiratory disease?
A
FEV1/FVC <0.7
FEV1
7
Q
What causes restrictive respiratory disease?E
A
ILDs e.g. IPF, sarcoid
Restriction makes lung volumes small and most of breath is out in first second
8
Q
What LFT results indicate restrictive respiratory disease?E
A
FEV1:FVC >0.7
FVC + FEV1 below predicted value
