The Fisher & Paykel MR850AEK is a high-performance respiratory humidifier designed for critical care environments. Suitable for both invasive and non-invasive ventilation, this system ensures optimal humidity and temperature delivery to protect airways and support patient comfort.

Engineered for compatibility with a range of ventilators, CPAP, and BiPAP devices, the MR850AEK uses intelligent auto-adjusting technology to deliver precise humidification. It helps improve airway clearance, reduce secretion build-up, and prevent drying of the mucosa, making it essential for patients requiring continuous respiratory support.

Note: Breathing circuits and humidification chambers are sold separately.
