Additional Information

Under-humidification and its consequences

During normal spontaneous breathing, the upper respiratory tract humidifies and warms inspiration gases to a physiologically appropriate level. Under these conditions, the lung will lose approximately 7 mg of water per liter of breathing gas. During tracheal intubation, however, this natural heating and humidifying system is bypassed by an endotracheal tube. As a result, precautions must be taken during mechanical ventilation to prevent cold and dry ventilation gases from damaging the delicate mucus membranes of the lower respiratory tract. An excessive loss of humidity will have deleterious effects on ciliated membranes and mucociliary clearance. Retention of secretions, cell defects, atelectasis, and pneumonia may result.

Pall HME20 and HME40

Maximizing physiological water retention

By maintaining the physiological lung atmosphere, the mucociliary clearance mechanism remains intact. This is essential to rid the lungs of particulate and microbial contamination. As passive humidifiers, the Pall HME20 and HME40 do not create water 'rain out', a potential patient distress and infection risk associated with ICU ventilation. 

Safety and economy

The airflow resistance of both the Pall HME20 and HME40 has been validated not to increase significantly over the maximum use life of 48 hours. Safety and outstanding performance make the Pall HME20 (pediatric/small adult size) and HME40 (adult size) the most effective and economical choices in modern airway humidification.
