OBSTRUCTIVE APNEA [1 record]

Subject field(s)
  • Respiratory Tract
  • Symptoms (Medicine)
DEF

An apnea either as the result of obstruction of the air passages or inadequate respiratory muscle activity.

CONT

Apnea, obstructive and central, also has been associated with aspiration of gastric contents. Laryngospasm is manifest as obstructive apnea secondary to reflux. Classically, obstructive apnea occurs within 1 hour after a feed when a patient suddenly stops, becomes apneic, stares, and develops a rigid opisthotonic posture. Continued ineffective respiratory effort is observed, but coughing or gagging is not necessarily present. If this progresses, pallor, cyanosis, and possible hypotonia ensue. The complete obstruction of the larynx impedes air movement, causing an obstructive picture.

OBS

This type of apnea often occurs during sleep, when pharyngeal muscle tone is low. Recurrent obstructive apneas during sleep characterize the obstructive sleep apnea syndrome.
