Diagnostic Techniques
Fast and Efficient Diagnostics
Sefam NightScan PG Polygraphy
Polygraphy is an effective way to detect breathing disorders in patients, conducted outpatient. NightScan allows precise tracking of key parameters such as airflow, heart rate, and oxygen saturation. The lightweight and compact device allows patients to move freely during sleep with minimal discomfort. The high data sampling frequency ensures recording quality, and the simple NightScore software facilitates analysis. Polygraphy is affordable, enabling quick and precise diagnosis, making it ideal for initial sleep apnea detection.
Detailed analysis for a comprehensive diagnosis
Sefam NightScan PSG polysomnography
Polysomnography represents the most detailed method of analyzing sleep disorders because it records all important physiological signals. NightScan PSG and NightScan PSG Pro provide comprehensive diagnostics using EEG, EOG and EMG sensors. The ability to display data in real time improves the experience for both doctors and patients. These devices enable detailed monitoring of brain, muscle and breathing activity, ensuring a precise and comprehensive assessment. The built-in infrared camera and customizable software additionally improve the possibilities of analysis and creation of reports. Basic package includes (other items optional): 11-channel polygraph, 2 L-sized RIP belts (thorax/abdomen), extra cable for RIP belt, SpO₂ ring piston of soft silicone (for adults), 1 pack of nasal-oral cannulas (10 pcs), CPAP adapter, small AASM connection box, combined RESP sensor (includes 2 PLM sensors), 1 pack of gold electrodes with 75 cm cup (10 pcs), LIC2Pro Conductive Cream, NUPREP Abrasive Skin Prep Gel, 1 Pack of Disposable PLM Electrodes (30 pcs), Docking Station (Includes USB Cable), Carrying Case and NightScore Software.
FAQ
Polygraphy tracks basic parameters, while polysomnography includes additional sensors for monitoring brain activity, eye movements, and muscle tension, providing a comprehensive picture of the patient’s sleep state.
NightScan is a lightweight, easy-to-use device that the patient attaches to the body as instructed, recording all key parameters needed to analyze breathing during sleep.
The recording typically lasts an entire night, or 6-8 hours, to collect data from all
sleep stages.
Yes, polygraphy can be conducted at home, while polysomnography is usually performed in a lab setting for precise data collection.
Polysomnography is necessary for more complex symptoms, such as frequent nighttime awakenings, parasomnias, or suspected complex respiratory and sleep disorders.
NightScan PSG devices are highly accurate, with automatic sensor recognition and quality equipment ensuring reliable and precise results.
Data is processed in NightScore software, where respiratory events are automatically detected and adjusted as needed, with a custom report generated.
Results are typically available soon after data analysis, depending
on the complexity of the processing and the need for additional analyses.
Most devices, such as the NightScan models, are designed to be as lightweight and non-invasive as possible, minimizing the impact on the patient's sleep.
Polygraphy at home provides accurate results for basic breathing disorders, but for more detailed information, laboratory polysomnography is recommended.
Preparation includes reducing caffeine and alcohol intake, avoiding heavy meals before sleep, and ensuring a comfortable environment for recording if conducted at home.
