Asthma Flashcards
Is asthma chronic or acute?
Chronic
Why is breathing difficult in asthma?
Because the airways in the lungs become inflamed (swollen) thus making it narrow.
True or false: Asthma is curable.
False - Asthma can be controlled/managed.
How can asthma be managed?
By avoiding triggers, through medication, and following a treatment plan.
True or false: Once people develop asthma, they’re likely to have it for life.
True - Even if they don’t have any symptoms or feel fine - asthma is still there and can flare up at any time.
What is a key feature of asthma?
Chronic airway hyperresponsiveness.
What is chronic airway hyperresponsiveness?
A condition where the airways in the lungs are overly sensitive and react strongly to various stimuli. The airways can constrict/narrow more easily and more intensely than in those without the condition, leading to asthmatic symptoms.
Label the missing parts.
Define ‘atopic’.
Sensitivity to allergens.
Symptoms of asthma are different for everyone but most people who have asthma have one or more of these symptoms?
- Coughing – often worse at night
- Wheezing – whistling or squeaky sound when you breathe
- Chest tightness – feel like something is squeezing or sitting on your chest
- Shortness of breath – feels like can’t get enough air out of their lungs.
In asthma, the symptoms often follow a pattern. What are they?
- They come and go over time or within the same day.
- They start or get worse with viral infections, such as a cold.
- They are triggered by exercise, allergies, cold air, or breathing too fast from laughing or crying.
- They are worse at night or in the morning.
What are 3 ways asthma affect the airways?
- Airways are swollen and doesn’t leave enough room for air to move through.
- Bronchospasm occurs.
- Glands in the airways produce thick mucus, which further blocks the airways.
What happens if asthma is not properly managed?
Repeated exposure to asthma triggers will exacerbate the inflammation, leading to worsening symptoms
When does usually asthma start?
During childhood when the body’s defense system is still taking shape.
What is adult-onset asthma?
Asthma that develops in adulthood.
What is the exact cause of asthma?
Exact causes are unknown and may be different from person to person.
Many factors may work together to cause people to develop asthma. These are?
- Things in the environment (called allergens)
- Viral infections
- Family history
- Allergies
- Obesity
- Race or ethnicity
- Sex
- Occupational hazards
- Climate change
(See notes for more detail on each of these).
Define ‘asthma triggers’.
Things that set off or make asthma symptoms worse.
Name some asthma triggers.
- Indoor allergens
- Outdoor allergens
- Emotional stress
- Physical activity
- Infections
- Certain medicines
- Poor air quality or very cold air
(See notes for more detail on each of these).
How are the types of asthma classified?
Classified into various types based on their causes or triggers.
Name 6 types of asthma.
1) Allergic Asthma
2) Eosinophilic Asthma
3) Exercise-Induced Asthma
4) Cough Variant Asthma
5) Nighttime (Nocturnal) Asthma
6) Occupational (Work-Related) Asthma
(See notes for more detail on each of these).
How is asthma diagnosed?
There is no single test for asthma. Doctors make the diagnosis of asthma when a person has breathing symptoms typical of asthma that come and go.
What are 2 tests that test lung function and breathing?
1) Peak flow measurements
2) Spirometry
The following is what level (classification) of asthma?
- Symptoms occur less than twice a week, and nighttime symptoms occur less than two times per month.
- Lung function tests are 80% or more above predicted values. Predictions are often made based on age, sex, and height.
- No medications are needed for long-term control.
Mild Intermittent Asthma.
The following is what level (classification) of asthma?
- Symptoms occur three to six times per week.
- Lung function tests are 80% or more above predicted values.
- Nighttime symptoms occur three to four times a month.
Mild Persistent Asthma.
The following is what level (classification) of asthma?
- Symptoms occur daily.
- Nocturnal symptoms occur 5 or more times per month.
- Asthma symptoms affect activity, occur more than two times per week, and may last for days.
- There is a reduction in lung function, with a lung function test range above 60% but below 80% of normal values.
Moderate Persistent Asthma.
The following is what level (classification) of asthma?
- Symptoms occur continuously, with frequent nighttime asthma.
- Activities are limited.
- Lung function is decreased to less than 60% of predicted values.
Severe Persistent Asthma.
What is childhood asthma?
Childhood asthma is the same lung disease that adults get, but kids often have different symptoms.
What is another name for childhood asthma?
Pediatric asthma.
Define constrict.
Make something narrower or tighter by squeezing or compressing it.
Name 5 signs and symptoms of childhood asthma.
1) Shortness of breath.
2) Rapid breathing.
3) A cough that gets worse after a viral infection, such as a cold or the flu.
4) Wheezing, a whistling sound when breathing in or out.
5) Seesaw motions in their chest (retractions).
(more signs and symptoms in notes)
Name 5 risk factors for childhood asthma.
1) Genetic risk factors
2) Environmental risk factors
3) Natal risk factors
4) Gender - boys are more likely than girls
5) Medication exposure
(more detailed information in notes)
When can adult-onset asthma begin?
Asthma that begins any time after the age of 20.
Who is more likely to get adult-onset asthma?
- Women with hormonal changes (pregnant or experiencing menopause).
- Those exposed to environmental irritants.
- People with allergies, especially to cats.
- People who have GERD.
- People who are exposed to environmental irritants.
