The Phasitron®

The Phasitron® is our patented open-circuit technology that makes HFPV possible. All Percussionaire® devices use a Phasitron® to safely and precisely provide lung expansion, secretion clearance, and oxygen for a wide range of clinical conditions and applications -- from home care to intensive care.








 
 
 

The Phasitron®

HFPV is possible because of the patented device called the Phasitron®. The Phasitron® is a unique venturi that acts as a “clutch” mechanism to protect the lung from over pressure. By automatically adjusting to the resistance of the lung, the Phasitron® precisely and safely delivers the optimal volume and pressure of air required by the alveolar space.

  

  • All Percussionaire devices use the Phasitron® to safely and precisely provide HFPV in one convenient delivery system.
  • The Phasitron® is an open breathing circuit which accommodates any patient lung volume regardless of compliance.
  • It works equally well for most patient populations.

Pulsatile Flow

The flow created by the Phasitron® is known as Pulsatile Flow which bathes the alveoli in fresh oxygenated air while gently washing out CO2 and secretions.

Pulsatile Flow

Airway Clearance

HFPV is a Pulsatile Flow that mobilizes and removes mucus and debris, while gently recruiting alveoli and restoring FRC. Unlike external percussion that may drive secretions deeper into the lung, the Pulsatile Flow continues to dislodge debris and secretions which are carried out by the exiting airflow.

Airway Clearance

Lung Recruitment

Over time, the Pulsatile Flow gently persuades distal airways and collapsed alveoli to open which keeps lung supported and respiring while atelectasis, infection, inflammation, and injury can heal.
