Puritan Bennett 840

Puritan Bennett 840 Features

The Covidien Puritan Bennett 840 ventilator provides a solid foundation on which to build your ideal ventilation solution. With the addition of optional advanced technology upgrades,the pb 840 can meet the specific needs of practically every patient type you care for—from neonatal patients weighing as little as 300 grams to adult patients weighing as much as 150 kg.

• Advanced Technology: DualView touchscreens, High-performance pneumatics, and dual-microprocessor electronics.
• Easy Upgrades: Software can be upgraded and customized to meet a variety of future clinical needs.
• Enhanced noninvasive ventilation (NIV) for use with a stable respiratory drive.
• Data Integration: Supports communication with all major patient monitoring and hospital information systems for use in electronic data transfer.
• Optional Clinivision® Mobile Patient Charting software provides the ability to practice evidence-based medicine.
• Low Overall Cost of Ownership: The Puritan Bennett 840 Ventilator is engineered with high volume environments in mind. It is durable, reliable, and easy to service.
