What is obstructive or central apnea?

Apnea: Hello. The diagnosis of apnea (a temporary stoppage of respiration or breathing) depends on the cause. Central means that the brain isn't sending the appropriate neural impulses for breathing. Obstructive apnea refers to an anatomical blockage (most commonly upper airway like tongue, tonsils and/or soft palate) causing the breathing to stop. Both are dangerous and need evaluation and treatment.
