The Standard of All Sleep Apnea Testing


What is a Standard Polysomnography?

A polysomnography is a test that can determine what problems are present during sleep.
Brainwaves, eye movement, a spirogram, respiratory capacity, electrocardiograms, SpO2,
and leg movement are all shown on one screen to monitor all physical activity
while sleeping. Since it is an examination done while sleeping,
testing is available at all times to fit all sleep schedules.

Types of Analyses Done by Certified Sleep Polysomnography

The polysomnography includes many different types of equipment,
and through a detailed analysis, we are able to diagnose the diseases while the patient is asleep.
When getting the diagnosis, there are many sensors attached to the body so it may seem awkward at first,
but we pride ourselves in providing state of the art facilities for a comfortable diagnosis.

  • Analysis of Sleeping

  • Analyze Brainwaves (EEG) and Eye Movement (EOG)

    The changes between NREM (Non Rapid Eye Movement) 1st degree, 2nd degree,
    3rd degree, 4th degree and REM (Rapid Eye Movement)
    during sleep is analyzed

  • Analysis of Breathing
    While Asleep

  • Respiratory Air Flow Sensor (temperature/pressure sensor),
    Thorax/Abdomen Movement Belt, Etc.

    - Check if there’s light-breathing/no-breathing while asleep
    - Analyze the duration and the number of times repeated in order to see
    the smoothness in breathing

  • Analysis of Movement
    While Asleep

  • Analyze muscle condition (EMG), sleeping position sensor, etc

    Electromyogram of both arms and legs and sleeping position sensors help
    review the vibrations of the muscles while asleep

  • Cardiovascular

  • Measure the heart rhythm (ECG) and Oxygen
    concentration sensor, etc.

    Record oxygen concentration, heart rate, electrocardiogram (ECG)
    while patient is asleep

  • Overall Condition

  • Video recorded

    - While the patient is asleep, the sleeping process will be recorded
    - Assess overall sleeping condition

Testing Process

  • Book an Appointment

    Since there are preparations for the testing, one should come to the hospital about 1~2 hours before you hope to sleep.

  • Fill out Survey

    Since it is important to know certain data for an accurate examination, one must fill out a questionnaire about their sleep before the polysomnography.

  • Connect Sensors

    After taking a shower in the shower room and changing into clothes for the testing, a RPSGT will put sensors onto the patient’s body. The sensor is in stick-on format so it will not sting or stimulate anything.

  • Check Sensors

    After adding all of the sensors, simple commands will be given to test out the sensors. After the test, one may fall asleep.

  • Sleep

    One may sleep comfortably as they normally would/

  • Reserve Consultations and Discharge

    When the patient wakes up (whenever they please), the test ends and they can go home. If one wants to receive the results within the day and talk with the specialist, it will take roughly 2hours to examine and analyze with the results and it will take about 1 hour for consultation.
