QuickLung Jr.® is an adjustable, precision test lung for pediatric ventilator testing and training. It is compact, easy-to-use, and capable of simulating a wide range of patient conditions, including patient inspiratory efforts. You can use QuickLung Jr. alone, or customize according to your needs by adding options such as active breathing, graphics, intubation, and more.

Intended Use

  • Ventilator performance verification: combine with any flow/volume/ pressure analyzer for a complete ventilator testing system
  • In-service training and sales demonstration
  • Basic mechanical ventilation training
  • Compatible with all ventilators, from ICU to transport

Impressive Performance

Accurate and versatile

Bellow-style test lung provides more linear and predictable respiratory simulation than a bladder-style test lung.


No external gas source required.

Simple manual adjustment of resistance, compliance, and leaks.


No other test lung performs at this level of precision and versatility at this price

  • Compact 7.5” x 11” footprint. Works accurately from a table or suspended from a ventilator.
  • Ventilator triggering: Detachable QuickTrigger® feature simulates a physiologically-correct inspiratory effort (negative pressure).
  • Regulatory compliance: Easily adjustable parabolic resistance and compliance settings correspond to IEC 60601-212 ventilator performance standards.
  • Versatile: QuickLung Jr. is the core of a modular system with options for a variety of applications.

Q: Can I use two QuickLung Jr.'s to simulate left and right lungs?

A: Yes. They can be T’d together in parallel to demonstrate compartmentalized lung problems (different compliances resistances and leaks).

Q: How do I set resistance on the QuickLung Jr.?

A: The QuickLung Jr. uses orifice-type resistors which require a simple turn of the elbow connector to access one of three standard settings (5, 20, 50 cm H2O /L/s).  Additional resistances can be created by adding the Parabolic Resistor Ring.

Q: Can I set inflection points on the QuickLung Jr.?

A: Yes. An upper inflection point can be set by using the enclosed velcro strap to restrict the expansion of the bellows.

Q: Can I use the QuickLung Jr. on any ventilator?

A: Yes, just like a real patient the QuickLung Jr. can be attached to any ventilator from ICU to transport.

Q: Can the QuickLung Jr. be calibrated?

A: The QuickLung Jr. cannot be calibrated.
