Fisher & Paykel Temperature Probe – 900MR805
The Fisher & Paykel 900MR805 Heater‑Wire Adapter is a respiratory humidification accessory used with heated breathing circuits in clinical ventilation systems. It connects the heated wire circuit to the humidifier, allowing electrical power to be delivered to the inspiratory and expiratory limbs of the breathing circuit.
This adapter plays an important role in maintaining stable airway humidity and temperature during respiratory therapy. By powering the heated wires inside the breathing circuit, it helps keep water vapor above the dew-point temperature, significantly reducing condensation buildup within the circuit.
Designed for compatibility with respiratory humidifiers such as the Fisher & Paykel MR850 Respiratory Humidifier and Fisher & Paykel HC550 Humidifier, the adapter integrates with RT-series dual heated breathing circuits used in ventilators and respiratory support systems.
Its durable medical-grade cable and secure connector design ensure reliable performance in demanding hospital environments, supporting consistent humidification and improved patient comfort during ventilation therapy.
Clinical Application
The 900MR805 heater-wire adapter is used in respiratory therapy systems that require controlled heated humidification of inspired gases. Maintaining appropriate temperature and humidity helps protect airway mucosa and improves patient comfort during ventilation.
Typical clinical settings include:
Intensive Care Units (ICU) for mechanically ventilated patients
Operating theatres during anaesthesia ventilation
Respiratory therapy departments
Neonatal and pediatric ventilation systems
High-flow oxygen therapy and humidified respiratory support
By enabling heated breathing circuits to function correctly, the adapter helps prevent condensation in ventilator tubing and ensures consistent delivery of warm, humidified gases to patients receiving respiratory support.
