Q

The difference between COPD and Asthma

A

Asthma
* Young age onset, usually < 20 years.
* History of hay fever, eczema and/or
allergies.
* Family history of asthma.
* Symptoms are intermittent with periods
of normal breathing in between.
* Symptoms are usually worse at night or in
the early hours of the morning, during an
upper respiratory tract infection, when
the weather changes, or when upset.
* Marked improvement with beta2 agonist.
COPD
Differences between asthma and COPD
* Older age onset, usually > 40 years.
* Symptoms slowly worsen over a long
period of time.
* Long history of daily or frequent cough
before the onset of shortness of breath.
* Symptoms are persistent rather than only
at night or during the early morning.
* History of heavy smoking (> 20
cigarettes/day for ≥15 years), heavy
cannabis use, or previous TB.
* Little improvement with beta2 agonist.

Q

symptoms of emphysema and chronic bronchitis

A

Symptoms
* chronic cough with/without sputum production on most days for 3 or
more months for 2 or more consecutive years
* Dyspnoea / shortness of breath
* Wheezing
The onset is very gradual with progressively worsening symptoms. Due to
the large reserve capacity of the lungs, patients often present when there is
considerable permanent damage to the lungs.
* Manifestations of right-sided heart failure
* Acute bronchitis after a cold / flu

Q

COPD medicine treatment Step 2

A

If not controlled on SABA alone and diagnosis was confirmed by
spirometry (with < 2 exacerbations per year): ADD
* Long-acting β2-agonist (LABA), e.g.:
* Formoterol, inhaled 12 hourly.
OR
If not controlled on SABA alone and spirometry not available:
* Inhaled LABA/corticosteroid combination e.g.:
* Salmeterol/fluticasone, inhalation, 12 hourly.

Replace with:
* Inhaled LABA/corticosteroid combination e.g.:
* Salmeterol/fluticasone, inhalation, 12 hourly
If not controlled on step 3: ADD

Q

treatment of acute exarcebation and note

A

Oral corticosteriods
Prednisole, oral 30mg daily, 5 days
Oral corticosteroids may be required for acute exacerbations,
but these have severe long-term complications and should only be
used long-term if benefit has been proven by lung function testing.
