Heated Wire Ventilator Circuit

Listing ID #394365

We are offering heated wire ventilator circuit. A heated wire ventilator circuit is used to humidify the gas delivered to a patient during positive-pressure ventilation. During humidification, gas passes over a water reservoir, where it is heated and saturated with water vapor. As the humidified gas passes through the breathing circuit, it cools and condenses; to compensate for this, the gas in the humidifier is heated above 37o c. However, under some circumstances, this hot gas may reach the patient without cooling, possibly causing thermal injury. In addition, the accumulation of the condensate in the breathing circuit changes the ventilator's flow dynamics and can be carried over to the patient by a delivered breath. To improve humidification and reduce the amount of condensate, as well as to eliminate the need to overheat the gas in the reservoir, clinicians can use a heated-wire humidifier. In this type of humidifier, a heated, insulated wire in the breathing circuit warms the gas and the walls of the breathing circuit. Heating of the wire depends on the voltage supplied to it by the humidifier, its impedance, the heat transfer between the breathing circuit and the surrounding environment, and the flow of gas in the breathing circuit. A circuit may operate without any problems when first set up for a patient, but may overheat when operating conditions change. additional information
