Pulmonary Clinical Medicine V: Pediatric Pulmonology Flashcards
What is vocal cord dysfunction (aka paradoxical vocal fold motion disorder) characterized by?
What does is cause in the flow volume loop?
(HYHO)
1) Abnormal closing of the vocal cords making it hard to move air in and out of lungs
2) Truncated inspiratory portion of loop
What age group is most susceptible to vocal cord dysfunction?
Which sex?
1) Teenagers
2) Females
Classification of asthma is determined by assessment of?
HYHO
1) Impairment (symptoms)
2) Risk (# of exacerbations requiring steroids)
What is the suspected diagnosis if a child presents as breathlessness while at rest, silent, and is noticeably drowsy/confused?
Imminent respiratory arrest
What are first line options for acute exacerbation of asthma?
(HYHO)

Where is CFTR located?
It is a disease of what function that involves multiple organ systems?
(HYHO)

CFTR encodes for a protein that functions as a?
cAMP regulated Chloride channel across epithelial cells
What population does CF affect the most?
HYHO

1) Respiratory (O2)
2) Cardiac (pump, perfusion, BP)
3) Circulatory volume (perfusion, BP)
Most pediatric arrests are due to?
Respiratory issues
What does restlessness, anxiety and combativeness in a child suggest?
Hypoxia
