The Smiths Medical Heat Moisture Exchanger (#570017) is a passive humidification device designed to warm and humidify inspired air for tracheostomy and ventilated patients. By capturing heat and moisture from exhaled breath and returning it on the next inhalation, this HME helps maintain airway moisture balance — reducing the risk of secretion retention and airway complications.

• Passive heat and moisture exchange — no external humidifier required
• Maintains optimal airway humidity and temperature for patient comfort
• Reduces risk of mucus plugging and airway dryness
• Lightweight, low-profile design for minimal patient burden
• Compatible with standard tracheostomy tubes and ventilator circuits
• Single-use for infection control
• Latex-free
