Who needs somnography

Computer somnography helps identify breathing disorders during sleep (in particular, obstructive apnea). In addition, this method accurately determines the duration and structure of sleep. It also allows you to assess the impact of respiratory disorders on different stages of sleep (REM and NREM) and dependence on posture.

Main indications for the study:

  • Obstructive sleep apnea. Due to obstruction (blockage) of the upper respiratory tract, breathing periodically stops during sleep. Against the background of this condition, hypoxia (lack of oxygen in the blood) often develops. It also leads to an increased risk of hypertension (high blood pressure), heart disease and stroke.
  • Restless legs syndrome. This condition is characterized by involuntary movements of the limbs during sleep. Against the background of this syndrome, chronic fatigue develops. Due to constant awakenings, a person becomes restless, and the quality of his life decreases noticeably.
  • Night breathlessness syndrome. This condition is associated with sudden awakenings. In this case, there is a feeling of lack of air. Against this background, chronic fatigue is often observed.

Unregulated sleep apnea contributes to the development of hypertension, myocardial infarction and stroke. And chronic fatigue and impaired concentration lead to deterioration of memory and cognitive functions.

General information

Step-by-step research

To identify pathology, specialists use the WatchPAT device. This allows you to determine the duration and structure of sleep. This method also helps to identify the connection between respiratory disorders and different stages of sleep.

24 hours before the study, you should stop using alpha blockers. 3 hours before the procedure, you must stop taking short-acting nitrates.

The WatchPAT itself resembles a fitness bracelet and is easy to put on your finger. The patient installs the device before going to bed. After this, he can sleep in his usual conditions. The next day the client returns the device to the clinic.

Information from WatchPAT is read and processed automatically. As a result, the specialist receives the following data:

  • Duration and structure of sleep
  • Apnea-hypopnea index
  • Relationship of breathing disorders with REM and NREM stages of sleep
  • Positional dependence

Use of the WatchPAT device is not recommended for children under 12 years of age or people with atrial pacing. Another contraindication is persistent non-sinus arrhythmia (atrial fibrillation or frequent extrasystole).

Results and data interpretation

Several indicators are examined in the process. Here they are:

  • PAT signal. Reflects the blood supply to the arteries of the finger
  • Saturation (SpO2). Blood oxygen level

The pulse is also examined during the process. This is due to the fact that the heart rate also increases against the background of respiratory disorders.

Data interpretation

Changes in the PAT signal, pulse and saturation are processed by a special algorithm. Here's how the results are interpreted:

  • PAT signal drop. This indicates disturbances in the blood supply to the arteries of the finger. This is associated with respiratory disorders
  • Decreased saturation. Indicates a decrease in blood oxygen levels during episodes of apnea or hypopnea
  • Changing heart rate. Indicates activation of the sympathetic nervous system. This occurs with respiratory disorders

WatchPAT is the only device that calculates the Apnea/Hypopnea Index (AHI) based on the patient's true sleep time. According to international standards, the validity of research results using this device is 90%. Therefore, you can be confident that our testing and diagnostics are based on proven and recognized standards.

Survey

8 questions

Scale for calculating the risk of
obstructive sleep apnea

  • 1

    Do you snore loudly (louder than you speak, or loud enough to be heard behind a closed door)?

  • 2

    Do you often feel tired and sleepy during the day?

  • 3

    Has anyone told you that they have observed you stop breathing in your sleep?

  • 4

    Do you have high blood pressure or are you taking medications for hypertension?

  • 5

    Is your BMI (body mass index) greater than 35kg/m2?
    BMI is calculated using the formula: weight (kg) / height (m)2.< /small>

Frequently Asked Questions

Doctors at K+31 addressed the most common questions about the computer somnography technique. Here are the main ones.

How are research results reported?

Research results are provided in the form of a detailed report. It includes graphs and tables with breathing indicators, apnea index, sleep phases, body position and pulse oximetry. A doctor's report with treatment recommendations is also attached.

After receiving the report, the patient needs to visit the specialist again. This is necessary to discuss the results in detail and obtain further recommendations.

How can I get diagnosed with sleep apnea at the K+31 clinic?

To undergo diagnostics of sleep apnea at the K+31 clinic, you need to contact with the hospitalization manager. The list of basic hospital services includes monitoring of breathing parameters during sleep using WatchPAT 300 and daily monitoring by a physician.

Can a patient use WatchPAT independently?

Yes, the WatchPAT device can be used at home - it is extremely easy to use. At an outpatient appointment, the doctor programs the device and gives instructions in 15 minutes. The patient independently installs the device 10 minutes before bedtime, and returns it to the medical facility in the morning.

Thanks to the high accuracy of automatic data decoding, the doctor receives the results of the study in a couple of minutes.
