ME-Series  Dryer Placement Recommendations

ME™-Series dryers are very efficient in removing water vapor from breath. The recommended location for placing the dryer is at the patient. The combination of increased temperature and high velocity of the breath as it exits the patient enable the breath to pass through the dryer before water vapor has condensed. A 4 to 6 inch length of tubing will remove 70 to 90% of the water vapor in a breath sample.

The dryer should be attached to the patient mask or tracheal tube. It can also be attached to a cannula if patient breath is sample with this device. Placing the dryer at the proximal side of the circuit enhances the performance in drying breath.

If the dryer is placed at the instrument inlet or distal side of the sample line, care must be taken to prevent liquid water from entering the dryer. If liquid water passes through the dryer, the transport of the liquid will cause the temperature of the dryer to decrease as the latent heat of vaporization produces a large cooling effect. This may cause additional condensation as the temperature of the dryer is decreased. Although part of the liquid water will pass through and evaporate on the outer surface of the membrane, the large amount of water may flow down the dryer and into the analyzer. If a hydrophobic filter is placed at the dryer outlet before it enters the analyzer, it may stop the water and gas flow, the dryer should not be used to evaporate liquid water. (CONTINUE) Placement inside the analyzer.
