Clinical presentation

Minor degrees of obstruction may manifest during increased respiratory rate and inspiratory flow, as may occur during exercise. Advanced signs of obstruction are as follows: extreme agitation and anxiety; inability to phonate; inspiratory stridor and gasping respirations; use of respiratory accessory muscles, nasal flaring, and suprasternal and intercostal recession; tracheal tug and paradoxical chest and abdominal wall movements; upright posture dependence.

Diminishing stridor, diaphoresis, cyanosis, hypertension, and evidence of severe hypoxemia and hypercarbia (loss of consciousness and cardiac arrhythmias) are late manifestations of obstruction and are grave prognostic signs.
