- chronic inflammation of bronchi makes them narrower
- excessive suptum
- hypersensitive airways

17
Q

What is chronic bronchitis?

A

Inflammation and excessive mucus production in the bronchial tree

18
Q

In which illness are the alveoli not seriously effected and diffusion of gases remain relatively normal?

A

Chronic bronchitis

19
Q

What is emphysema?

A

Pathological changes in the lung, usually end of a process that has been progressing. Usually followed by chronic bronchitis

20
Q

In which illness if there a permanent abnormal enlargement of the air spaces beyond the terminal bronchioles and destruction of the alveoli?

A

Emphysema

21
Q

As emphysema decreases the surface for gas exchange, the resistance to pulmonary blood flow is what?

A

Increased

22
Q

What are some of the symptoms of emphysema?

A
  • reduced elasticity, trapping air making lungs become fibrous
  • reduction in arterial PO2, increased RBC production
  • expiration is a muscular act
  • barrel shaped chest
23
Q

What are some symptoms of the COPD worsening (acute exacerbation)?

A
  • increased dyspnoea
  • increased sputum
  • increased cough
  • increased wheeze
  • reduced retention
  • increased fatigue
  • acute confusion
24
Q

What are the signs and symptoms of a severe COPD episode?

A
  • marked dyspnoea
  • tachypnoea
  • purse-lip breathing
  • acute confusion
  • use of accessory muscles
  • new-onset cyanosis
  • new-onset peripheral oedema
  • marked reduction in activities of daily living
25
Q

What are some causes of exacerbation of COPD?

A
  • common cold
  • flu
  • COVID
  • air pollutants
26
Q

How would you manage COPD?

A
  • early resp assessment inc SPO2 levels (aim for 88-92%)
  • ask what normal SPO2 is
  • nebulisation with salbutamol and assess response
    comfortable patient position
27
Q

What are bronchodilators?

A

Oxygen, salbutamol, ipratropium bromide

28
Q

How many minutes should you limit oxygen drive nebulisation for?

A

6 minutes

29
Q

What are time critical features of COPD?

A
  • major ABCD problems
  • extreme breathing difficulties
  • cyanosis
  • hypoxia unresponsive to oxygen
  • exhaustion
30
Q

What is a PE?

A

Pulmonary Embolism, a blood clot impairing blood supply to the lungs

31
Q

What causes a PE?

A

Usually a deep vein thrombosis travelling from the leg to lungs

32
Q

What are the symptoms of a PE?

A
  • unexplained shortness of breath
  • pleuritic chest pain
  • sinus tachycardia
  • reduced SPO2/ hypoxia
  • haemoptysis
  • signs of DVT
33
Q

What are specific questions you should ask for a PE?

A
  • recent surgery
  • recent myocardial infection
  • family Hx of DVT/PE
  • pregnancy
  • immobilisation
34
Q

How do you manage a PE?

A
  • oxygen therapy
  • ECG 12 lead
  • SPO2
  • IV access
  • wells score
  • NEWS 2
  • prepare to resuscitate
  • pre alert
35
Q

What does a wells score of more than 6 suggest for a PE?

A

That there will be a high probability of a PE

36
Q

What does a wells score between 2-6 suggest about a PE?

A

A moderate probability of PE

37
Q

What does a wells score of below 2 points suggest for a PE?

A

Low probability of a PE

38
Q

What is pneumonia?

A

Inflammation in the lungs usually caused via infection, that develops over several days

39
Q

What are the symptoms of pneumonia?

A
  • confusion, resp distress and cyanosis, dyspnoea, pleuritic chest pain, malaise
  • older patients may have a minimal cough and no fever but confusion and hypothermia
  • a lower lobe infection can cause upper abdominal pain which can be referred to ask the shoulder
40
Q

What are the causes of pneumonia?

A

Flu , hospitalised patients, cigarette smokers, excess alcohol, bronchiectasis, bronchia obstruction, immunosuppression, aspiration and IV drug use

41
Q

How do you manage pneumonia?

A
  • resp assessment inc SPO2
  • oxygen therapy
  • obs
  • NEWS 2
  • think sepsis!
42
Q

What can respiratory infections cause?

A
