Apnea Alarm

Apnea, or "Apnea" is a technical term for suspension of breathing. An apnea event is defined as a cessation of breath for a minimum of 10 minutes, with an excitation neurological and / or oxygen desaturation of the blood three to four or more. Sleep apnea is a disorder of breath during sleep that can lead to serious consequences such as heart failure.

There are three types of sleep apnea is central sleep apnea, Obstructive sleep apnea and complex sleep apnea (a combination of both). Central sleep apnea is caused by the imbalance of the brain's control center of the airways, while obstructive sleep apnea is caused by obstruction of the airway muscle tone decreased or increased soft tissue around the airway (by example, obesity or aging). Obstructive sleep apnea is about 84% of cases of sleep apnea, sleep apnea complexes represent about 15% and central sleep apnea, an increase of 0.4%. [A]

The symptoms of obstructive sleep apnea often loud snoring, restless sleep, and daytime sleepiness. The treatment of this type of sleep apnea is usually the use of respiratory treatments, such as continuous positive airway pressure (CPAP). other habits that contribute to symptoms of sleep apnea is smoking, alcohol consumption, or lose large amounts of weight.

Because of lower oxygen levels and increased levels of carbon dioxide during sleep, hypoxia and hypercapnia are usually the result of central sleep apnea. Therefore, hypoxia and hypercapnia have effects on the human body and can cause more serious health problems, angina, cardiac arrhythmia attacks or, at worst, sudden death. [2]

The tests for the diagnosis of sleep apnea are home oximetry readings or polysomnography in a sleep clinic. Oximeters that measures blood oxygen levels is a necessary device for measuring the normal stats in the body of a person while they sleep. According to the results of a study published in the January 15 issue of the American Journal of Respiratory and Critical Care Medicine.

"The practical purpose of diagnostic evaluation in most cases of obstructive sleep apnea is to predict which patients have symptoms that will improve treatment. Portable monitors record mainly oxygen saturation, can be used at home without supervision, and are less expensive [than] the polysomnography. "

oximeters OctiveTech offer a flexible and affordable for people suffering from sleep apnea and their physicians to monitor blood saturation during sleep. We especially recommend the handhelds that sounds a certain concentration of oxygen in the blood.
