The Volara System: Oscillation & Lung Expansion Therapy (OLE)

The Volara system can make it faster and easier to deliver oscillation & lung expansion (OLE) therapy to a broader range of patients throughout the hospital — and even at home.



Deliver timely, clinically proven Oscillation and Lung Expansion (OLE) therapy in just ten minutes with the Volara system from Hillrom.

The system uses alternating cycles of Continuous Positive Expiratory Pressure (CPEP) and Continuous High Frequency Oscillation (CHFO), combined with aerosol delivery, to help your patients get more value from their OLE therapy.


Treat and help prevent pulmonary atelectasis by combining continuous positive pressure with aerosol medication to help expand and hold the airways open.


This pneumatic form of chest therapy delivers continuous pulses of positive pressure, combined with aerosol medication, to mobilize and treat retained secretions.


Integrated with CPEP and CHFO for the most efficient treatment, the aerosol delivery system delivers medication during therapy to help loosen secretions.

The Volara System's treatment-in-process screen shows alternating periods of CPEP and CHFO therapies.


Volara system's wide pressure range allows you to treat more conditions.


Pre-sets for standard or customized therapy programs save you time.


The Volara system is portable and can be used anywhere in the hospital.


The Volara system's therapy interfaces are simple to operate.

  • 1.6-day reduction in average length of hospital stay1
  • 2-day reduction in average length of ICU stay1
  • 68% reduction in average time on a ventilator1
  • Associated with a reduction in ICU bounce-back from 12% to 0%2
