Abstract
The VDR-4 (R) high-frequency percussive ventilator (HFPV) has been shown to be beneficial in the management of inhalation injury by improving secretion clearance while maintaining oxygenation and ventilation. Delivery of gas flow during HFPV could lack adequate humidification delivered to the patient because a major portion of the delivered gas flow would bypass the humidifier when using the original VDR-4 (R) ventilator circuit. The authors tested a novel inline vaporizing humidifier and two gas-water interface humidifiers during HFPV using the new VDR-4 (R) Fail-safe Breathing Circuit Hub (R) to determine whether delivered humidification could be improved. This new humidification system, the Hydrate Omni (TM), delivers water vapor into the gas flow of the ventilator circuit rather than water droplets as delivered by the gas-water interface humidifiers. Measurements of absolute humidity and gas temperature were made on the three different humidification systems using a test lung model under standard ambient conditions. The authors found that when using the novel inline vaporizer, it provided better humidification when compared with the standard gas-water interface humidifier during HFPV using the new VDR-4 (R) breathing circuit.
