Polysomnography and polygraphy

Polysomnography is an advanced diagnostic method in sleep medicine that is used to investigate sleep disorders such as sleep apnea, insomnia and restless legs syndrome. This method records a variety of body activities during sleep, including brain waves, blood oxygen levels, heart rhythm and breathing movements. This detailed information allows doctors to accurately diagnose the causes of sleep disorders and develop customized treatment plans. Polysomnography is mainly concerned with the detection of apnea (reduction in respiratory flow by more than 80 % for more than ten seconds) or hypopnea (Reduction in respiratory flow by more than 30% for more than ten seconds). A common diagnosis is obstructive sleep apnea syndrome (OSA). Treatment is initiated on the basis of the data obtained during polysomnography. The most common and effective treatment for severe sleep apnea is CPAP therapy.


A simplified form of polysomnography is called polygraphy. In most cases, the patient is given a recording device and can sleep at home in a familiar environment. The following parameters are measured during polygraphy: Respiratory effort, snoring, oxygen level, body position, and pulse.


Nasal cannulas are used in both polysomnography and polygraphy examinations to measure respiratory effort and snoring. More precise nasal cannulas provide better results for a reliable diagnosis.

Oxygen Supply

Nasal cannulas for oxygen supply are the most commonly used medical product for oxygen therapy worldwide. Numerous patient groups are dependent on an additional oxygen supply.

Do you have questions about nasal cannulas?

What are nasal cannulas?

The nasal cannula is a medical product that can be attached directly to the nose. The nasal cannula is used to detect respiratory signals such as respiratory flow or snoring in sleep diagnostics, but also for oxygen supply in patients suffering from COPD or asthma, for example. The design with the soft nasal prongs is comfortable to wear and is used, for example, in oxygen therapy or sleep diagnostics. In the field of sleep diagnostics, the quality of the nasal cannulas is extremely important, as the quality of the signals is important for a reliable diagnosis. In addition, high wearing comfort is necessary for long-term measurements.
There are two categories of nasal cannulas in the field of oxygen supply: Low-flow nasal cannulas and high-flow nasal cannulas. Depending on the doctor’s recommendation or diagnosis, different nasal cannulas can be used for optimum oxygen supply.

What are nasal cannulas used for?

In sleep diagnostics, the nasal cannula is used to measure respiratory flow and, if necessary, snoring. The cannula system is directly connected to the sleep diagnosis device or sleep screener via the Luer-Lock connection. In this way, the nasal cannulas help to control the nasal and/or oral airflow.
For oxygen supply, the nasal cannula supports optimal oxygen supply to the patients. This involves medical ventilation. For this purpose, the cannula is connected to an oxygen device. The nasal cannula supplies oxygen to the patient via tubing and nasal prongs to the nostrils.

Who are nasal cannulas suitable for?

With their different sizes, the modern nasal cannulas are suitable for children and adults. They can be used in the sleep laboratory to detect health problems caused by snoring or breathing disorders. The nasal cannulas provide a high wearing comfort which is a very important point when examining the sleep of people who snore or have difficulty breathing.

How do you use the nasal cannula?

The nasal cannula can be attached directly under the nose of the person being analyzed. The nasal tips (prongs) are positioned directly under the nostrils. With the help of the adjustable loops, the nasal cannula adapts to the head so that it remains in the correct position during sleep.
To ensure that the test subjects or patients do not feel uncomfortable (in case of oxygen masks), the oxygen mask must fit their anatomy perfectly. This depends on the one hand on the size and adaptability of the nasal cannula and on the other hand on the type of oxygen supply.

How are the nasal cannulas connected?

In the sleep laboratory or hospital, other test devices are used in addition to the nasal cannulas. These include sensors that monitor physical activity during sleep. This enables comprehensive monitoring of heartbeats, eye movements and muscle activity. The nasal cannula itself monitors breathing. An oximeter, which is attached to the finger, is responsible for measuring the oxygen concentration. There may also be belts that measure the respiratory effort in the chest and abdominal area.
For a comprehensive sleep diagnostics, the nasal cannula is connected to analysis devices. This enables the sleep researchers to detect unusual activities of the body. This gives them the opportunity to analyze sleep patterns in detail.

In which areas are nasal cannulas used?

Sleep diagnostics uses nasal cannulas to monitor respiratory flow, snoring and other processes during sleep and make a diagnosis based on the data collected. Detailed sleep examinations are possible with the cannulas. In sleep medicine, the main task of nasal cannulas is to monitor respiratory flow. If necessary, this is followed by individual sleep therapy. This aims to improve the oxygen supply to body. This in turn leads to healthier sleep, which results in significantly more rest.

Polysomnography (PSG) deals with precise examinations that focus on the quality of sleep. Specific disorders can often be identified by evaluating of data from the sleep diagnostics in sleep laboratory or during a home sleep test. Several physiological activities play a role here. The measurements of the sleep diagnostics enable a precise analysis of:

  • Breathing,
  • heart activity,
  • brain waveform (EEG),
  • eye movement (EOG) and
  • muscle tension.

High-quality nasal cannulas, sensors and electrodes are essential for this analysis data. The information collected can be used to identify acute or chronic illnesses. In the case of problems such as breathing interruptions or sleep apnoea, doctors advise suitable therapy. This should optimize the breathing supply so that sleep provides the desired rest.

What types of nasal cannulas are there?

The nasal cannulas differ in their application (sleep diagnostics, oxygen suppy, and COs sampling), as well as different designs for adults and children. Tube length and the shape of the nasal prongs as well as the distance between the nasal prongs are the two important variables that are optimized with regard to the application and target groups. When selecting the optimal nasal cannula, the patient’s age and the aim of the treatment must be taken into account. There are also different connectors for the nasal cannulas so that the product can be used with different devices and for different applications.


The CNSAC nasal cannulas are suitable for children or adults, depending on the size. The standard models allow simultaneous measurement of nasal and/or oral airflow. This is where the advantages of the modern nasal/oral cannula become apparent. The exemplary list provides a brief overview of the most important oxygen goggles:
