bunnell gentle ventilation

Superior ventilation for our most vulnerable patients.

The 203 “Jet” is our original ventilator model. Bunnell services and rents the 203 LifePulse HFJV.


Bunnell 203 Jet Ventilator

Here’s how Bunnell is better.

Our LifePulse 203 jet ventilator provides very small tidal volumes. When combined with short inspiratory times, this superior ventilation creates the lowest possible peak and mean alveolar pressures.

Gentle breaths from the LifePulse prevent airleaks and even allow them to heal. Adjustable inspiratory time enables iT ratios up to 1:12, making passive exhalation possible.

The LifePort™ Endotracheal Tube Adapter provides easy access to High-Frequency Jet Ventilation.

Simply replace the 15-mm adapter on a standard endotracheal tube with the LifePort™ adapter and start high-frequency jet ventilation. The LifePort™ provides reliable pressure monitoring and effective jet gas delivery.

The 15-mm connector allows PEEP and “sigh” breaths from a conventional ventilator to be delivered in tandem with the high-frequency breaths from the Life Pulse®. This combined capability provides greater therapeutic flexibility and allows fine-tuning of the ventilator strategy to meet the patient’s specific needs.

The jet port on the side of the adapter redirects Life Pulse® breaths toward the lungs. The shape and velocity of these breaths enable them to deliver fresh oxygenated gas deep into the lungs using smaller tidal volumes and less pressure than conventional ventilators.

Patient Circuit

Patient Circuit Kit

Catalog #938

The HFJV Patient Circuit Kit contains all the disposable items necessary to provide a patient with high-frequency jet ventilation:
2 Life Pulse® HFJV Patient Breathing Circuits

The HFJV Patient Breathing Circuit is a one-piece disposable humidifier cartridge and patient breathing circuit that delivers heated, humidified gas from the ventilator to the patient for up to 7 days of continuous use.

6 LifePort™ Endotracheal Tube Adapters
• 2 each 2.5 mm
• 2 each 3.0 mm
• 2 each 3.5 mm​
• 4.5 and 5.5 mm can be special ordered

The LifePort™ Endotracheal Tube Adapter provides a convenient method of operating the Life Pulse® in tandem with a conventional ventilator.

Optional Add-ons

These optional accessories make using the LifePulse 203 easier and more convenient. To order these, contact customer support.


HFJV 203 Patient Box Catalog #312

WhisperJet Patient Box

Catalog #312

The Whisper Jet Patient Box makes the Life Pulse® High-Frequency Ventilator a uniquely effective mode of ventilation, by allowing the inhalation valve and pressure transducer to be placed close to the patient. This close proximity makes the small high-velocity breaths more effective and facilitates fast and accurate pressure monitoring. The result is a system that responds to changes in your patient, moment to moment.

  • Sealed Enclosure: Dramatically reduces noise and keeps fluids out
  • Connection: Located on the rear panel (not compatible with LifePulse 204)
  • Pressure Transducer: Positioned to minimize potential fouling
  • Pinch Tubing Capture: Designed to hold the pinch tubing more securely
  • Flexible Cable: Reduced stiffness allows for hassle-free placement

An Intro to the LifePulse 203, for Trained LifePulse 204 Users

This overview of the LifePulse 203 covers its systems in detail, outlining how it differs from the 204. Designed for clinicians who already understand the LifePulse 204, this video will cover the 203 in detail, from ventilator setup to a description of panels and specific alarms.
