At night if our airway obstructs, often we hear load gasping sounds with violent jerking body movements. This indicates that the airflow is occluded and our oxygen is diminished. The Greek word apnea is a term describing a condition without breath. Cessation of breathing (apnea), is a clear sign that a more serious sleep disorder exists. Sleep testing is necessary to determine if there is obstructive, central or mixed sleep apnea.
