Sonomedic Polysomnography System

The Sonomedic Polysomnography System is an advanced diagnostic device utilized in sleep laboratories and hospitals to conduct full overnight sleep studies. It captures up to 70 channels of physiological data to diagnose complex sleep disorders like central sleep apnea, narcolepsy, and periodic limb movement disorder.

Parameters Monitored

Brain & Muscle: EEG (brain activity), EOG (eye movement for REM detection), and EMG (muscle activity).
Respiration: Airflow, chest/abdominal breathing effort, and snore detection.
Vitals: ECG (heart rate) and SpO₂ (oxygen saturation).

System Features

Records high-resolution signals integrated with AASM standard automatic scoring software.
Intelligent sensor auto-recognition and optional HD touch displays for bedside impedance checks.

ResMed ApneaLink Air (Level 3)

The ResMed ApneaLink Air is a Level 3 sleep study device specifically designed for Home Sleep Testing (HST). It is a highly convenient, cost-effective alternative to in-lab polysomnography for patients suspected of having Obstructive Sleep Apnea (OSA).

Key Features & Setup

Core Monitoring: Monitors 4-7 key parameters including Nasal airflow, SpO₂, Heart rate, and respiratory effort.
Patient Friendly: Lightweight and designed for extremely easy, unassisted setup by the patient at home.
Data Transfer: Features wireless data transfer to local software or the cloud for immediate clinical review and automatic scoring.

Clinical Applications

Initial screening for sleep-disordered breathing.
Follow-up evaluation for patients already using CPAP/BiPAP therapy.
