COPD Flashcards
What is COPD?
Refers to emphysema and chronic bronchitis. Chronic obstructive pulmonary disease.
What is emphysema?
Destruction of alveoli
This reduces surface area for gase exchange and impaired lung function
What is chronic bronchitis?
Inflammation and irritation of bronchial tubes.
Airways become swollen and excess mucus is produced obstructing airways.
What are symptoms of COPD?
Dyspnoea
Cough
Wheezing
Chest tightness
What are the contraindications for exercise in COPD?
Sever hypoxia
Recent MI 3-6 months
Unstable angina
Recent exacerbation of COPD requiring hospitalisation
Infection
Severe hypotension
What are possible assessments for COPD?
2-minute walk test
Modified BORG
BODE index
- BMI
- Obstruction of airflow
- Dyspnoea
- Exercise e.g. 6-minute walk test / 2 minute walk test
Auscultation
Respiratory Rate
How is the 2 minute walk test performed
- Walk as far as possible in 2 minutes
- Can use walking aids
- Should be independently mobile
~ 15m course
What are predicted distances for populations in the 2-minute walk test?
Women 257.177 - (0.723 x age) - (1.688 x BMI)
Men 279.096 - (0.998 x age) - (1.426 x BMI)
What are the areas of the modified BORG dypnoea scale?
0 - nothing at all
0.5 extremely slight (just noticeable)
1 very slight
2 slight
3 moderate
4 somewhat severe
5 severe
6
7 very severe
8
9 extremely severe (almost maximal)
10 Maximal
What cardiorespiratory exercises can be done for COPD?
ACBT
- breathing control
- Thoracic expansion
- Huff
Pursed lip breathing
Rectangular breathing
Blow as you go breathing
What is ACBT?
Breathing control
Thoracic Expansion exercises
Huff (forced expiratory technique)
What is breathing control in ACBT?
- Breathing control
- Hand on stomach gentle rise and fall diaphragm
- Ideally in through nose and out mouth
- Can use pursed lip breathing
- Gradually slow breaths
- 3-5 cycles
How is thoracic expansion exercise completed in ACBT?
Thoracic expansion exercises (TEE)
- Relax chest and shoulders
- Hands on ribs
- Take long slow and deep breath in through nose
- Hold breath 2-3s
- Gentle and relax breath out
- Repeat 3-5 times if let headed back to breathing control
How is Huff completed in ACBT?
Huff
- Medium or high volume
- Medium normal in long out
- High deep in quick out
What is pursed lip breathing?
Good for asthma, COPD and pulmonary fibrosis
Relax your neck and shoulder muscles
Breathe in slowly through nose with hand on stomach
Purse lips as though going to whistle or blow on hot drink
Breathe out slowly and gently through lips for 4 or more seconds
