Overview:

Promote more natural breathing with innovative features.

At Medtronic, we believe ventilation can and should be more natural.

Our PAV™*+ software is a breath type that better manages a patient’s work of breathing and supports more natural breathing compared to conventional mechanical ventilation.^

In addition to PAV+ software, the Puritan Bennett™ 840 ventilator also features a full suite of software options, safety features and accessories to fit a variety of patient needs, from infant to adult.

Features:

The Puritan Bennett™ 840 ventilator features our PAV™*+ software, a breath type that better manages a patient’s work of breathing and supports more natural breathing compared to conventional mechanical ventilation.^

With the addition of optional advanced technology upgrades, this ventilator 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.

With the Puritan Bennett™ 840 ventilator, Medtronic:

  • Provides clinically exceptional technology that helps keep patients and clinicians safe
  • Protects capital investment with an upgradeable pathway
  • Focuses on service, support and education
  • Enables the benefits of fleet standardization
