What is sleep apnea?

 After years of work and research during which incidents of snoring and obstructive sleep apnea were studied a  new  website of digital recording and analysis of breath during  sleep was created.

 Characteristics of the snore check method 


 Diagnosis and consignment of the answer through the net to  the doctor.

 By systemizing it snorecheck was rendered a practical guide  and online medical tool in medicine.

 This method gives the doctor the ability to have an explicit image of the upper respiratory system’s constraints  during sleep.

It helps the doctor to have evaluated quantitative and qualitative information.

If respiration is arduous or laborious.

If respiration is oral or nasal.

If snoring is mild or intense, oral or nasal.

If characteristics and indicative sounds exist such as those of the soft palate and uvula.

With this method all pathological data of breathing during sleep are recorded and analyzed.

Respiratory difficulties and snoring are related to hypopnea and apnea, to what extent and in what sequence.

The answer also contains characteristic segments of the recording which can be listened to both by the patient himself and the attending doctor.

The medical analysis of the recording is combined with the evaluation of a detailed case history which involves a questionnaire, as certain physiological body’s elements of the examinee are taken into account.

 Snoring is the vibration of respiratory  structures and the resulting sound, due to  obstructed air  movement during breathing  while sleeping. In some cases the sound  may be soft, but in other  cases, it can be  loud and unpleasant. It has been noticed  that snoring is more frequent to  overweight  people, those who have been born with  narrow passages mostly at the mouth-  pharynx's entrance or short neck. It  appears  more often to men than women.  Some factors may  worsen snoring  such as  alcohol, tranquillizers , sleeping pills and smoking. 

 Until recently, snoring was considered to be a normal variation of breathing, mostly annoying to  those who sleep together. However, medical research has shown that snoring does not consist  of normal breathing and in many cases may be a sign, or fist alarm of derangement with severe  consequences.



 Classification of respiratory's characteristic sounds during sleep with the digital  analysis method, called snore check.


  difficult nasal breathing at a side position

  steadily difficult (laborious) nasal breathing

  alternation of nasal and mouth breathing

  nasal inhalation and oral exhalation (with or without the  characteristic  “switch”  sound that is provoked by the soft  palate and uvula during  exhalation)

  oral breathing (inhalation and exhalation)


  mild and periodic oral snoring

  mild and periodic nasal snoring

  permanent soft oral snoring

  permanent loud oral snoring

  alternation of soft and loud snoring during the changes of  the position  of the head  


  snoring with episodes of hypopnea

  specially intense snoring after episodes of apnea

  apnea from the beginning of sleep

  apnea that appears after interval of intense snoring (due to overdrying    and stress' edema)

  apnea during only the last one to third of sleeping

  apnea in supine position

  apnea in supine and side positions

  apnea with short duration

  apnea with long duration


Nasal breathing due to the anatomy of the nose and variable volume of the passages causes resistance while the air is entering. This resistance consists of almost 50% of the whole resistance of the upper airway. Nasal valve is mostly the area that resistance is created (in the initial degree,at the entrance of the nose). That explains the fact that track athletes' breathing is effectively improved while nasal strips or speculum have been proved equally effective. Research has shown that every alternation of the nasal resistance significantly affects the the pharynx's amplitude. Decreased nasal breathing provokes reflexive pharynx stenosis and as a result snoring, hypopnea and apnea. This pharynx's blockage is preserved even though nasal breathing is improved mostly due to increasing surface tension which has been provoked by a more mucous production.That's why complete nasal blockage may provoke episodes of hypopnea and apnea while it lasts even to people with normal breathing. Nasal breathing is influenced and as a result more increased nasal congestion is provoked.

Nasal sinus, polypus, allergies, vasomotor, chronious rhinitis, sinusitis may influence the incoming air and provoke increased nasal resistance with or without changes of the head and body during sleep.

The circle alternation of congestion – decongestion (plugging-unplugging) of the nose due to lower nasal niches's dilation also happens during sleep. Reflexive stopping of the nasal circle has been noticed while the counterpart side of the thorax is pressed. What also deserves to be mentioned is that 3 and 4 stages of the sleeping are lost because of significant nasal congestion and more episodes of awakening happens during sleep (upper airway resistance syndrome).   


Is caused by obstruction of the upper airway. It is characterized by repetitive pauses in breathing, called apneas, typically lasting from a few seconds to minutes. They often occur 5 to 30 times or ore an hour. During these pauses snoring is stopped and begins more loudly when breathing is resumed. If the someone has lots of episodes of apneas and some other symptoms appear such as drowsiness and weariness he is thought to be suffering from sleep apnea syndrome.  

 It is remarkable that apnea with short duration and small  number of episodes may not provoke other symptoms  and as a result sufferers ignore its existence. As time  passes the number of episodes may increase and  symptoms appear . That helps us to suspect the sleep  apnea syndrome. At the beginning, these symptoms are  few and light. On the other hand, while the number of  episodes increase more symptoms appear as a result encumbering  those already existing.  

Many sufferers of sleep apnea syndrome mention that they have been snoring for years. Husbands or wives observe that snoring and breathing stops for a while while they try to breathe and their thorax and abdomen move. Sometimes they nudge them in order to breath. Patients themselves usually do not realize these apneas and on occasion they wake up with the feel of drowning. Their sleep may be wearisome while they try to breath.  This intense muscle movement is responsible for severe sweating. Night frequent urination is also possible. As for sour taste and heart burn may be present because of froward of the stomach's content.

In the morning, they often wake up with headache or heavy head and dry mouth and throat and they feel that they have not rested. They may also be nervous and moody or they feel chagrin.

Another important symptom that is mentioned is decreased sexual ability. Besides these symptoms blood oxygen is decreased while carbon dioxide is increased when respiratory disease or coronary heart disease exist and as a result these hypoxaemias are life threatening. That is because while the oxygen is decreased to lower levels the existing disease worsens or new hazardous heart arrythmias appear and even death may result.

These apneas and decreased blood oxygen have the result to increase the blood pressure and heart vessels are harmed. It has been found that 30% of patients with high blood pressure suffer from sleep apnea. For this reason the sufferers who snore need to be examined so that apneas be noted. These apneas require therapy and if they are cured then high blood pressure will cease.
