Promote more natural breathing with innovative features

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.


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 standardisation
