Nasal cannulas: An indispensable tool in polysomnography and polygraphy
The world of sleep medicine has made significant progress in recent years.
This is primarily due to innovative technologies and devices that provide more precise insights into the complex nature of human sleep. One of these instruments, which plays a central role in both polysomnography and polygraphy, is the nasal cannula. These specialized devices are not only essential for conducting comprehensive sleep studies, but also significantly improve the quality and accuracy of the data collected.
The role of nasal glasses in sleep diagnostics
Nasal prongs are used to measure respiratory flow by continuously recording air movements through the nose during inhalation and exhalation while sleeping. This data is invaluable to sleep medicine specialists, as it provides insights into different breathing patterns and can reveal potential airway narrowing that may indicate sleep apnea or other sleep-related breathing disorders.
Nasal cannulas are indispensable in polysomnography (PSG) —a comprehensive sleep study that measures various physiological parameters during sleep. They enable detailed information about respiratory flow to be recorded, supplemented by other important data such as heart rhythm, brain activity, and muscle movements.
Nasal cannulas also play a central role in polygraphy (PG), a simplified form of sleep diagnostics that is primarily used to diagnose sleep apnea. Although polygraphy is less comprehensive than polysomnography, it still provides valuable insights into the patient's respiratory function during sleep.
Advantages of using nose glasses
The biggest advantage of nasal cannulas is their ability to measure respiratory flow non-invasively, accurately, and continuously. These characteristics make them a preferred tool in sleep diagnostics—both in terms of patient comfort and safety.
In addition, nose glasses are:
- Easy to use: Its straightforward handling enables smooth application both in clinical settings and during home examinations.
- Compatible: They can be easily connected to various diagnostic devices and are therefore flexible for use in different examination scenarios.
- Efficient: By providing accurate data, nasal cannulas help improve diagnostic accuracy and support the development of targeted treatment plans.
Feedback from a satisfied customer
"We are very satisfied with the use of the CNSAC nasal cannulas. Our unclassified apnea has dropped to zero. Initially, it was still at 30–40% with other nose clips. Thank you very much for your support."
This feedback underscores the high quality standard and reliable performance of CNSAC nasal glasses in everyday diagnostic practice.
Conclusion
The integration of nasal cannulas into polysomnography and polygraphy practices has permanently changed the diagnosis and treatment of sleep disorders. By providing essential data on respiratory flow, they enable specialists to gain a deeper understanding of their patients' sleep quality and quantity.
In modern sleep medicine, nasal glasses are therefore much more than just a technical aid—they are an indispensable partner on the path to better sleep and better health.
