Asthma Flashcards
Essentials of DX for what issue
(1) Episodic or chronic symptoms of wheezing, dyspnea, or cough.
(2) Symptoms frequently worse at night or in the early morning.
(3) Prolonged expiration and diffuse wheezes on physical examination.
(4) Limitation of airflow on pulmonary function testing or positive Broncho provocation challenge.
(5) Reversibility of airflow obstruction, either spontaneously or following bronchodilator therapy.
Asthma
Asthma is a common disease, affecting approximately what % of the population?
8–10%
It is slightly more common in what demographics?
male children (younger than 14 years) female adults
What is a chronic disorder of the airways characterized by variable airway obstruction, airway hyperresponsiveness, and airway inflammation
Asthma
What is the most common phenotype of asthma?
Allergic
True/false
Allergic asthma usually begins in childhood and is associated with other allergic diseases such as eczema, allergic rhinitis, or food allergy
True
What is characterized by episodic wheezing, shortness of breath, chest tightness, and cough.
Asthma
During severe asthma exacerbations, airflow may be too limited to produce wheezing, and the only diagnostic clue on auscultation may be _____________.
globally reduced breath sounds with prolonged expiration.
(normal/abnormal)
Arterial blood gas (ABG) measurement may be _______ during a mild asthma attack
normal
Ture/False
Respiratory alkalosis and an decrease in the alveolar-arterial oxygen difference (A–a–DO2) are common
False
INCREASE in alveolar arterial oxygen difference
During severe ASTHMA exacerbations,
______ develops and the PaCO2 returns to normal.
hypoxemia
CXR’s on asthma usually show what
usually normal or show only hyperinflation
may include bronchial wall thickening and
diminished peripheral lung vascular shadows
when is chest imaging indicated for asthma
pneumonia
another disorder mimicking asthma
a complication such as pneumothorax is suspected
The combination of an increased PaCO2 and respiratory acidosis may indicate what
impending respiratory failure
VENTALATE THAT MOFO
What are the five important aspects of chronic asthma management?
(a) Assessing asthma control and severity,
(b) Distinguishing between severe asthma and uncontrolled asthma,
(c) Personalized pharmacologic therapy for asthma,
(d) Treatment of modifiable risk factors and control of environmental factors
(e) Guided self-management education and skills training
