Explain the potential problem with heated wire circuits inside an inspiratory tubing.

What will be an ideal response?

One potential problem with this system is found when the distal temperature probe is placed at the patient connection inside a heated incubator that is set at a higher temperature than the humidifier. As the inspiratory tubing enters the incubator, the gas is heated to the set temperature of the incubator environment. This causes the temperature probe to sense the higher temperature and shut down the heater wires. The result is a buildup of condensation in the inspiratory tubing.
