Sleep tests


is performed to assess how the person is sleeping and whether respiratory problems occur during sleep. The main indication for such an examination is the suspicion of a respiratory disorder while asleep. The main symptoms include loud snoring, breaks in breathing while sleeping and a tendency to fall asleep under various circumstances.

This examination is also performed in patients suffering from insomnia who sleep poorly or often wake up at night. It consists of a continuous recording of a person’s sleep, which includes a record of the brain’s electrical activity, eyeball movement, and muscle work during sleep. An important element of the study is also a record of breathing activities: air flow through the airways, chest and abdominal respiratory movements, and oxygen content in blood. In addition, snoring sounds are recorded and body positions during sleep are monitored.



Preparation for the test :

  1. Preparation of the the Patient for the test (installation of all sensors, filling in the appropriate questionnaire, weighing, measuring) requires an appropriate amount of time, therefore we recommend that the Patient should appear in our Centre around 20:00. If teh Patient would like to freshen up before the examination, there is a bathroom with a shower in the ward.
  2. Please take your toiletries and a towel. For the examination, you should take 2-piece pyjamas with a shirt that can be unfastened from the front (this will make it easier for us to install electrodes and sensors). For Patients who are used to evening meals, it is possible to prepare such a meal. We kindly ask for such a request earlier.
  3. We would like to remind you at the same time to take or take with you all medicines taken in the evening and in the morning. This is particularly important for people treated for heart disease, hypertension, diabetes or chronic respiratory diseases.

It is very important that the Patient does not have too much trouble sleeping in the new place:

Course of the test

  • For the test to be meaningful it should last at least 6 hours (the longer the test the more information it provides). The important information for us is the time when the Patient usually falls asleep.
  • The whole process of sensor assembly and testing will be adjusted so as not to disturb the Patient’s daily cycle. If you are worried about something during the examination, or if you wake up because you have a condition or need to go to the toilet, please let the nurse on duty know.
  • The next morning all sensors and electrodes will be disconnected. The patient will be able to leave our Centre around 7 a.m. after filling in the appropriate form concerning the examination and quality of sleep. After a thorough analysis of the results, the specialist doctor will propose an appropriate treatment model.

Additional tests


Otherwise, the assisted breathing method. The patient sleeps in a mask, through which the device presses air into the airways all night. This seems unbearable, but patients who have been awake for years or awake several hundred times after the first night with CPAP do not want to give it up. The use of CPAP in night apnea syndrome gives an improvement in 95% of cases, causing normalization of sleep, improvement of the patient’s blood oxygenation during the night, resignation of daytime sleepiness, improvement of general well-being, and most importantly – significantly reduces the risk of complications such as heart attacks or strokes. KRAJMED offers its patients trial treatment with CPAP on a loan home for 1-2 nights.

Apnea Link

It’s screening = basic, easy to do sleep test. It gives a general indication of whether apnea is present and how dangerous it is. The result of the test makes it easier for the doctor to indicate the right recommendations.



It’s a truncated, simplified version of polysomnography. This examination is less accurate than polysomnography but in many cases it is sufficient to diagnose the problem correctly. The device allows you to diagnose sleep disorders at home, without the medical staff and hospital stay.

The polygraph records information about:

  • apnea, differentiating it in terms of breathing quality,
  • snoring, differentiating them in terms of breathing quality,
  • how the patient breathes in different body positions,
  • what’s the heart rate when you sleep and the blood oxygen saturation.
