The Refurbished Puritan Bennett 840 Ventilator is an advanced intensive care ventilator designed to provide flexible mechanical ventilation for neonatal, pediatric, and adult patients. The system features dual-microprocessor control, DualView™ touchscreen interfaces, and flexible breath-delivery technologies for critical-care environments.
The Puritan Bennett 840 platform combines patient monitoring and ventilator control through separate touchscreen displays and can be configured with ventilation modes and software options such as PAV+™, Volume Ventilation Plus, NeoMode, and Tube Compensation.
Product Description
The Puritan Bennett 840 is an ICU-grade mechanical ventilator built around a modular system architecture. Its ventilator base incorporates the blower/exhalation unit, while the system can be configured with an optional compressor, breathing circuit components, and an external Backup Power Source (BPS).
The DualView™ Graphic User Interface (GUI) separates patient-data monitoring from ventilator-setting controls, providing clinicians with dedicated touchscreen areas for viewing patient information and managing ventilation settings.

DualView™ Graphic User Interface
The Puritan Bennett 840 incorporates a DualView™ touchscreen interface designed to separate two important functions:
- Patient data monitoring
- Ventilator setting controls
This configuration allows clinicians to view patient-related information while accessing ventilation controls through dedicated touchscreen interfaces.
Dual-Microprocessor Ventilator Control
The ventilator base incorporates dual microprocessors that support the system's ventilator-control architecture.
The ventilator base also houses:
- Blower/exhalation unit
- Exhalation filter
- Collection bottle unit
- Dual microprocessors
This integrated architecture forms the central ventilator platform.
Ventilation Modes
Assist/Control (A/C)
Assist/Control mode provides mandatory ventilation while allowing patient-triggered breaths according to the configured ventilation settings.
Synchronized Intermittent Mandatory Ventilation (SIMV)
SIMV delivers synchronized mandatory breaths while allowing spontaneous breathing between mandatory breaths.
Spontaneous (SPONT)
The Spontaneous mode supports spontaneous patient breathing according to the selected ventilator configuration.
Advanced Software & Ventilation Options
PAV+™
PAV+™ (Proportional Assist Ventilation) is designed to track patient effort and provide proportional ventilatory assistance, supporting a more natural breathing pattern.
Volume Ventilation Plus
The Volume Ventilation Plus option combines:
- Volume Control Plus
- Volume Support
This provides additional flexibility for volume-targeted and supported ventilation.
Tube Compensation
The Tube Compensation feature automatically offsets flow-dependent pressure drops associated with artificial airways.
Core System Components
1. Graphic User Interface (GUI)
The DualView™ GUI incorporates dual touchscreens that separate:
- Patient data monitoring
- Ventilator setting controls
2. Ventilator Base
The ventilator base, incorporating the blower/exhalation unit, contains:
- Dual microprocessors
- Exhalation filter
- Collection bottle unit
3. Optional Compressor
An optional compressor can provide an independent medical-grade compressed gas source.
4. Breathing Circuit
The breathing circuit configuration includes:
- Inspiratory limb
- Expiratory limb
- Filters
- Water traps
- Humidifier pot
5. Backup Power Source (BPS)
The Backup Power Source is an external battery module designed to provide emergency power during situations such as:
- Transport
- Power interruption
- Loss of primary electrical power
