Polygraph (PG)

To detect obstructive sleep apnea (OSA), these two type of sleep studies can be conducted:Polysomnography (PSG) and Polygraphy (PG).

Polygraphy (PG): Home Sleep Apnea Test (HAST), this second type of study involves using a portable device at home to detect OSA.

Advantages of Polygraphy:

Convenience: unlike PSG, where you need an appointment with a technician, RP allows you to pick up the device and perform measurements at your convenience.

Ease of Installation: the devices are straightforward to set up.

Comfort: You get to sleep in your own bed during the test.

Cost-Effective: PG is more budget-friendly; its cost can be half that of a polysomnogram.

Effective for Obstructive Sleep Apnea Diagnosis: PG serves as a reliable test for diagnosing obstructive sleep apnea.

If you experience symptoms such as loud snoring, waking up in the middle of the night, fatigue, and daytime drowsiness, it’s essential to consult a specialist for examination. Depending on your doctor’s assessment, you may be prescribed a respiratory polygraph.

When prescribed a respiratory polygraph, patients receive a measuring device from their doctor’s office or a sleep clinic. Alternatively, a sleep technician may bring the device directly to the patient’s home. Patients follow the technician’s instructions on how to set up and use the device.Then, patients wear the device while sleeping. The device collects data related to breathing patterns, oxygen levels, and other relevant parameters. An additional sensor is attached to the body to monitor chest and abdominal movements during breathing. The device records various signals throughout the night, including airflow through the nose, oxygen saturation (SpO2), and snoring sounds. Patients can rest assured that the device won’t significantly disrupt their sleep.

The following day, patients return the device. Technicians and sleep specialists analyze the collected data. The primary goal is to detect obstructive sleep apnea (OSA) and assess overall sleep quality.

Ventmed’s polygraph, represents the latest generation of diagnostic devices. Its compact design, ease of use, expanded measurement channels, and advanced algorithms allow for more accurate diagnosis of sleep-related conditions, including sleep apnea syndrome.

    What is the difference between CPAP and BiPAP in the DF Series?
    CPAP provides a constant pressure throughout inhalation and exhalation, while BiPAP offers two pressure levels (higher for inhalation, lower for exhalation) for more comfort, especially for COPD or high-pressure patients.
    Who should use the DF Series CPAP/BiPAP device?
    It is suitable for patients with obstructive sleep apnea (OSA), CSA, MSA snoring, COPD, and obesity hypoventilation syndrome, as prescribed by a doctor.
    Can I use this device at home without hospital supervision?
    Yes, our sleep monitor model SF-A9 and SF-A10S polygraphy device is for home sleep test, and the CPAP machine also can be used for home care respiratory therapy.
    Does the device support mobile app monitoring?
    Yes, the new CPAP/BiPAP model DF series have WiFi/GPRS connectivity, allowing users and doctors to track therapy data via a mobile APP and cloud.
