In normal respiration the anatomy of the upper airway helps to warm and humidify inspired air, and to retain the warmth and moisture contained in expired air. During inspiration, even cold or dry air is typically heated to 37°C and when fully saturated, contains 44mg H2O/L. In normal respiration, the anatomy of the upper airway helps to warm and humidify inspired gas, and to retain the warmth and moisture contained in expired air. When you inhale, even cold or dry gas is heated to body temperature and by the time it reaches your lungs, it contains the correct amount of moisture. In mechanical ventilation or anaesthesia, the patient’s upper airway may be bypassed by the introduction of a tracheal tube. As a result the patient’s lungs may be confronted with cold, dry inspired gas.

Prolonged exposure to dry ventilatory gases can lead to:

• Localised inflammation of the trachea
• A reduction in ciliary function
• Retention and thickening of secretions
• Lowering of patient temperature
• Reduction in cardiopulmonary function
• Increased risk of tracheostomy tube occlusion
• Extended duration and cost of care.

HME and HMEF Media

Our range of Heat and Moisture Exchangers (HMEs) and Heat and Moisture Exchanging Filters (HMEFs) include foam or corrugated paper in combination with a filter pad. Regardless of which type of material, the aim is to provide a large surface area with low resistance to flow making them effective as a heat and moisture exchanger.

Humidification Effectiveness

The Intersurgical range of HMEs and HMEFs has been tested independently at TiM Germany(3) in accordance with the test methodology described in ISO 9360-1:2000(4).  Visit our filtration and humidification page for further details.

Heat and Moisture Exchangers (HMEs)

Our range of HMEs for ventilation and spontaneously breathing patients improve the humidification of inspired gases. Also known as passive humidification, this requires an HME to be positioned within the breathing system close to the patient’s airway.

The HME is designed to replicate the functions of the upper airway, conserving the patient’s own expired heat and moisture and returning it to the patient on their next inspiration.

We offer a wide and comprehensive range of HMEs with a variety of efficiencies, sizes and shapes to ensure maximum customer choice whilst meeting all clinical requirements. Take a look at our range below, or click on the image to visit the relevant product page.

The common features of Intersurgical’s HMEs include:

• Designed for use within anaesthesia, intensive care and home care environments.
• Whilst providing some physical protection they do not provide bacterial or viral protection for the patient.
• The humidity output for all HMEs is tested and validated in accordance with ISO 9360-1:2000(4).
