Puritan Bennett 840 Features

The Medtronic Covidien Puritain Bennett 840 is a ventilation system that can help patients from neonates to adults. The PB 840 features a PAV system that that helps support a more natural breathing pattern, making it easier for the patient to breath. The Ventilator has a LCD touchscreen display for monitoring where you can view both the data and the ventilation settings at the same time.

  • 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.
