You will find information about hypopnea syndrome here.
Hypopnea syndrome is a condition which involves periods of low respiratory rate or shallow breathing. It can happen both during sleep or waking hours. If it happens during sleep, then it is considered as a sleep disorder.
This disorder causes the oxygen level in the blood to drop, which causes restlessness, therefore disrupting stages of sleep.
The causes of hypopnea syndrome are aging, alcohol abuse, smoking, use of sedatives such as pills, obesity, neuromuscular diseases, respiratory muscle disorders, and nasal defects such as septum deformation.
The most common symptom that can be found in a person with hypopnea syndrome is excessive sleepiness due to constant interruption of sleep during the night. Majority of these people experience a loud and heavy snoring that is often followed by a choking sound then by episodes of silence- because insufficient air can enter the lungs through the nose and mouth. The series of silence has a duration of 20 seconds or longer, occurring several times in an hour, resulting in a poor sleep.
Other symptoms are forgetfulness, mood swings, depression, nervousness, lesser energy, morning headaches, and problems in concentrating.
Continuous positive airway pressure (CPAP) is the most common management of hypopnea syndrome. It is a kind of a treatment wherein the patient will have to wear a mask over the mouth or nose to facilitate entrance of air into the upper airway. The pressure of the air can be adjusted to maintain the correct levels of oxygen saturation in the blood.
Other treatments include losing weight, quitting smoking, avoiding sleeping on a prone position, and avoiding sedatives and hyptotics.
