Description

The MR850 humidifier (by Fisher & Paykel) is a medical device that adds warmth and moisture to respiratory gases for patients, used in hospitals for various therapies (adult, pediatric, neonatal) via masks or tubes, featuring simple one-button selection, smart alarms, and advanced algorithms to maintain optimal humidity levels for patient comfort and airway health, forming part of a complete system with heated circuits. Key Features & Functions: Gas Conditioning: Heats and humidifies breathing gases (like oxygen) to mimic natural body conditions, preventing airway dryness. Therapy Modes: Offers simple selection for different patient types (adult, pediatric, neonatal) with optimal settings, often using “Optimal” (37°C) or “Essential” (31°C) modes. System Integration: Works with specific breathing circuits (like Evaqua 2), probes, and adapters for a complete solution. Smart Technology: Uses advanced algorithms, flow sensors, and dual temperature feedback to adjust heating and minimize nuisance alarms, even during gas flow interruptions. Patient Comfort: Designed for comfortable, unobtrusive therapy, with features like soft nasal prongs and lightweight tubing for better patient mobility. Ease of Use: Simple controls, an easy-to-read display, and a clinically based alarm system make it user-friendly for clinicians. How it Works: Water Chamber: A consumable chamber is filled with water. Heating: An electric heating element warms the water and a heated plate within the chamber. Gas Delivery: Respiratory gas passes over the heated water, picking up moisture and heat. Delivery Circuit: Heated wires within the breathing circuit tubing prevent moisture from condensing, delivering warm, humidified gas to the patient via a mask or endotracheal tube.
