Portable Full Polysomnography SF-A22S Ventmed PSG

The Ventmed SF-A22S Portable Full Polysomnography (PSG) is an advanced sleep monitoring device designed for diagnosing sleep disorders. It collects, displays, stores, and analyzes respiratory physiological data with high precision. With its compact design, wireless capabilities, and user-friendly interface, it is ideal for both clinical and home-based sleep studies.

Key Features:

• Comprehensive Sleep Monitoring – Tracks multiple physiological parameters, including SpO₂, pulse rate, airflow, body position, and CPAP compliance.
• High Accuracy Sensors – Provides precise data collection for effective sleep disorder analysis.
• Wireless & Portable Design – Compact and easy to use for both clinical and home-based sleep tests.
• Real-Time Data Display – View and analyze sleep data on an intuitive display screen.
• Advanced Reporting – Generates detailed reports for diagnosing sleep apnea, hypopnea, and other disorders.
• User-Friendly Interface – Simple controls for easy operation and quick setup.

• NEW: double-sided, dual diaphragm chestpiece for both adult and paediatric assessment.
• NEW: The paediatric side is also easily transformed into a traditional open bell by replacing the single-piece diaphragm with the supplied non-chill rim.
• NEW: chestpiece is precision-machined into an aesthetically pleasing, less angular shape.
• NEW: single-piece diaphragm instead of separate diaphragm/rim making it easier to attach and easier to clean due to the smooth unbroken surface.
• NEW: The stem features an open side indicator to easily identify which diaphragm is in operation.
• NEW: next-generation tubing gives even longer tube life with improved resistance to skin oils, alcohol and staining.
• 3M’s ‘Tunable Technology’ lets you easily switch from low to high frequency sounds by switching from light to firm pressure on both the adult and paediatric sides of the chestpiece.
• High acoustic sensitivity when performing general physical assessment.
• Laser engraving of text and symbols to personalise your scope and avoid theft/loss
• Larger ear tubes on the anatomically designed headset comfortably positioned for better sound transfer. Easy adjustment by simply squeezing or pulling apart the eartubes.
• Comfortable Snap-Tight soft seal eartips create an excellent acoustic seal to reduce ambient noise.
• No natural rubber latex or phthalate plasticisers are used in the tubing or any other component—to help protect health and the environment.
• Complement your personal style with Littmann’s large range of chestpiece finishes and tubing colours.
• Used as a diagnostic aid as part of the physical assessment of a patient.
