SESSION CONTENTS
STEP 1: Presentation of Session Title and Learning Tasks (5 minutes)
READ or ASK students to read the learning tasks and clarify
ASK students if they have any questions before continuing
STEP 2: Common Disorders of the Respiratory System (10 minutes)
|Activity: buzzing (5 minutes) |
| |
|ASK students to pair up and buzz on the following question for 2 |
|minutes |
| |
|What are the common disorders of respiratory systems? |
| |
|ALLOW few students to respond |
| |
|WRITE their responses on the flip chart/ board |
| |
|CLARIFY and SUMMARISE by using the content below |
Respiratory disorders:
organs and tissues that make gas exchange possible in higher organisms,
bronchioles, alveoli, pleura and pleural cavity, and the nerves and
muscles of breathing
common cold, to life-threatening entities like bacterial pneumonia,
pulmonary embolism, and lung cancer
o Pharyngitis
o Epiglottitis
o Rheumatic fever
o Diphtheria
o Bronchiolitis
o Pneumonia
o Pertussis
o Tuberculosis
o Asthma
o Cystic fibrosis
o Lung cancer
o Chronic Bronchitis (bronchiectasis)
o Emphysema
o Chronic asthma
o Pulmonary oedema
o Pulmonary emboli
STEP 3: Common Disorders of the Upper Respiratory System (10 minutes)
|Activity: Brainstorming (5 minutes) |
| |
|Ask students to brainstorm on the following question: |
| |
|What are the common disorders of upper respiratory system? |
| |
|ALLOW few students to respond |
| |
|WRITE their responses on the flip chart/ board |
| |
|CLARIFY and SUMMARISE by using the content below |
infections in the world
o It is an inflammation of the throat or pharynx.
o It is often referred to as a sore throat.
o Acute pharyngitis can result in very large tonsils which cause trouble
swallowing and breathing.
o Some cases are accompanied by a cough or fever.
o Most acute cases are caused by viral infections, bacterial infections,
fungal infections, or irritants such as pollutants or chemical
substances.
o A very rapidly progressive infection causing inflammation of the
epiglottis and tissues around the epiglottis
o The infection is usually caused by bacteria and is contracted through
the respiratory tract
o An inflammatory disease that may develop two to three weeks after
bacterial(streptococcal) infection
o It is common in children
o It is an acute bacterial disease that usually affects the tonsils,
throat, nose or skin.
STEP 4: Common Disorders of the Lower Respiratory System
(15 minutes)
|Activity: Buzzing (5 minutes) |
| |
|ASK students to pair up and buzz on the following question for 2 |
|minutes |
| |
|What are the common disorders of lower respiratory system? |
| |
|ALLOW few pairs to respond and let other pairs to add on points not |
|mentioned |
| |
|WRITE their response on the flip chart/board |
| |
|CLARIFY and SUMMARIZE by using the content below |
o Inflammation of the bronchioles due to infections especially viral
o More prominent in individuals with asthma history and cigarette smoking
o Inflammation of lung with accompanying fluid build up
o Much of pneumonia seen clinically is caused by bacteria (Streptococcus
Pneumonia).
o Pneumocystis carinii pneumonia is most common to immune compromised
patients
o Pertussis, commonly known as "whooping cough," is an infection of the
respiratory tract caused by bacteria
o Is caused by Mycobacterium tuberculosis
o It can be inactive or active
o It is most prominent to HIV/AIDS patients and other immune compromised
patients.
o Is more characterised by chronic cough and night sweats
o Cystic fibrosis, lung cancer and asthma belongs to OPD
o Both may cause obstruction and inflammation
o Asthma
with hypersensitive airways
allergens like dust and cigarette smoke are the main cause
o Is the irreversible progressive obstruction of air flow in lungs
o Includes:
o Chronic Bronchitis (bronchiectasis)
such as textile dust fibers
o Emphysema
o Chronic asthma
o Pulmonary oedema
exchange and lung expansion
o Pulmonary emboli
impact.
STEP 5: Key Points (5 minutes)
world
o Bronchiolitis
o Pneumonia
o Pertussis
o Tuberculosis
STEP 6: Evaluation (5 minutes)
Step 7: Assignment (10 minutes)
|Activity: Take Home Assignment (10 minutes) |
| |
|DIVIDE learners in groups or individual. |
| |
|ASK the learners to work on the following assignment |
| |
|What are the common disorders of the lower respiratory system |
| |
|ALLOCATE time for learners to do the assignment and submit |
| |
|REFER learners to recommended references |
