Children with severe respiratory distress & a narrowed airway often sit in tripod position, leaning forward with arms on the legs. The head & neck are extended with the jaw thrust forward to help keep the airway open.
- this position may also be seen in a child with an acute asthma flare.
Croup

Stridor
KNOW THIS!!!!!
High-pitched sound generated from partially obstructed air flow in the upper airway
Epiglottitis
KNOW THIS!!!!!
Inflammation & swelling of the epiglottis & larynx

Bronchiolitis
KNOW THIS!!!!!
Inflammation & obstruction of the bronchioles
- lower respiratory infection (viral or bacterial)
- leading cause of hospitalizations in ages 1 year
