Description

Hudson's Humid-Vent line offers specialized heat and moisture exchangers (HMEs) and combined HME/bacterial-viral filters, designed to enhance respiratory care in clinical settings such as anesthesia, intensive care, and emergency care. These devices are crucial for maintaining optimal moisture and temperature levels in the respiratory tract of mechanically ventilated patients, while also providing effective filtration of inspired air in models equipped with filters.

Key Features

• Moisture and Heat Retention: Ensures the respiratory tract remains humidified and warm, mimicking natural conditions.
• Filtration Capability: Select models offer high-efficiency bacterial and viral filtration, safeguarding against airborne pathogens.
• Single-Use Design: Each unit is individually packaged to ensure sterility and prevent cross-contamination.

Material and Design

• Media Composition: Utilizes bacteriostatic, hygroscopic microwell paper and a hydrophobic, electrostatically charged polypropylene filter in filter models.
• Construction: Free from latex, PVC, and DEHP, minimizing allergic reactions and environmental impact.
• Housing: Transparent for easy visual inspection, with a compact and lightweight form to reduce dead space.

Connectivity and Compatibility

• Design Variants: Available in both angled and straight designs with ISO standard connectors, ensuring compatibility with standard 15mm or 22mm endotracheal tubes and breathing circuits.
• Sterility Options: Offered in both sterile and clean versions to meet diverse clinical needs.

Model Specifications

Humid-Vent Filter

• Efficiency: Filtration efficiency exceeding 99.9999% for both bacteria and viruses.
• Moisture Output: Up to 33 mg H₂O/L, varying with tidal volume.
• Dead Space and Resistance: Tailored for different patient sizes with specific dead space and flow resistance metrics.

Humid-Vent HME

• Variants: Includes models like Humid-Vent 1, Mini, and Micro+, each designed for specific patient groups from neonates to adults.
• Performance: Provides moisture output up to 30 mg H₂O/L with minimal resistance.

Usage Guidelines

• Placement: Positioned close to the patient within the breathing circuit for optimal performance.
• Duration: Typically replaced every 24 hours, with a maximum usage period of up to 4 days depending on clinical protocols.

Safety Considerations

• Contraindications: Not recommended for patients with high secretion volumes, large air leaks, or those requiring precise control of dead space.
• Potential Risks: Includes increased airway resistance if obstructed by secretions and the need for careful monitoring to prevent complications.

Benefits

• Ease of Use: Lightweight and less cumbersome, particularly beneficial during patient transport.
• Clinical Advantages: Reduces staff workload and the risk of ventilator-associated pneumonia, available in various sizes to suit different clinical demands.

Maintenance

• Replacement: Intended for single use only, should be replaced if visibly soiled or obstructed, in line with clinical guidelines.
