The Fisher & Paykel MR730 respiratory humidifier is designed to warm and humidify the respiratory gases administered to the patient. It uses an electronically controlled heating system combining a heating plate and, in heating circuit mode, a heating wire integrated into the respiratory circuit. Automatic temperature control maintains appropriate humidification conditions while minimizing condensation within the circuit.
 
 The MR730 features temperature probes for monitoring the temperature at the humidification chamber outlet and near the patient. Airway temperature is adjustable from 31 to 40 °C , with a resolution of 0.1 °C. A digital display allows monitoring of the measured temperature and key operating parameters.
 
 Designed for use in medical environments, the MR730 can be used with various Fisher & Paykel compatible breathing circuits and humidification chambers. Its PID control system ensures precise heating control and helps maintain constant temperature and humidity.

 The MR730 can also operate without a heating wire; in this configuration, regulation relies primarily on the heating plate and the probe located at the end of the circuit. The manufacturer indicates that this configuration improves safety, particularly at low flow rates, although humidification performance is less optimized.
