Fisher & Paykel M850/810 heated wire humidifier heating wire
Function of the Heated Wire Circuit
Purpose:
Connects the humidifier (MR850/810) to the breathing circuit. The built-in heating wire maintains gas temperature and humidity during delivery, preventing condensation ("rainout").
Key Components:
-
Heating Wire – Automatically regulates temperature (typically maintaining gas temperature at ~37°C).
-
Temperature Probe – Monitors gas temperature at the patient end and provides feedback to the humidifier for power adjustment.
-
Tube Design – Dual-coil structure (adult/pediatric circuits) with a waterproof layer.
