4
Q

What is chronic bronchitis

A

It causes thick sticky mucus to block up the airways and inflammation and swelling to further narrow the airway

9
Q

How can smoking lead to the development of COPD

A

Tobacco in cigarettes releases a reactive oxygen species (‘free radicals’)
This causes the inactivation of antiproteases leading to an increase in neutrophil elastase
Tissue damage occurs leading to emphysema

Q

What other things can increase neutrophil elastase

A

Nicotine in tobacco
IL-8 and TNF from free radicals
Both cause the release of neutrophils causing an increase in neutrophil elastase

22
Q

How can COPD be diagnosed

A

Through clinical history, examination and spirometry

23
Q

What will a clinical history show in COPD diagnosis

A

24
Q

What will an examination show in COPD diagnosis

A

May be normal
Tachypnoea

25
Q

What will a spirometry do in COPD diagnosis

A

It will confirm the diagnosis and assess the severity

26
Q

It is predicted to be severe

29
Q

What does it mean if the FEV1 is under 30%

A

It is predicted to be very severe

30
Q

What are the baseline tests used for COPD

A

Spirometry which records absolute and % predicted values
Chest X-ray
ECG
Full blood count (query anaemic/polycythaemic/eosinophilia)

A

Smoking cessation

32
Q

To relieve breathlessness caused by COPD what type of intervention should take place

A

Use of inhalers

33
Q

To prevent exacerbation from COPD what type of intervention should take place

A

Use of inhalers, vaccines, pulmonary rehabilitation (PR)

34
Q

To manage the complications of COPD what type of intervention should take place

A

Pulmonary rehabilitation
Nutritional assessment
Psychological support
36
Q

What are the benefits of pharmacological managements

A
