Pathogenesis of Wheezy Infant
Incidence of Wheezing
Infants are more susceptible to wheezing due to smaller airway diameter
Evaluation & Dx of Wheezy Infant
Evaluation & Dx of Wheezy Infant
- Pitch
- pitch of the wheezing depends on the degree of obstruction of the airway.
Evaluation & Dx of Wheezy Infant
- Timing
Wheezing is usually expiratory but may be inspiratory or both.
