Intrapulmonary Percussive Ventilation – what is it?

This is Bella getting an IPV treatment.  She actually seems to enjoy it.  She did not as an infant when they had to use the face mask now it just attaches to her trach.  It’s like CPT, but from the inside.  Here is more info about IPV (from http://tlforrette.com/IPV%20Clinical%20Application%20Guide.pdf)

Intrapulmonary percussive ventilation (IPV) is a form of chest physical
therapy administered to the airways by a pneumatic device. Using a
breathing circuit called a Phasitron, mini bursts of gas are delivered into the
lungs at rates between 100 – 300 breaths per minute (bpm). A high output
nebulizer provides a dense aerosol to deliver medications and hydrate
secretions. Percussive bursts of gas are delivered throughout the entire
respiratory cycle which loosen and mobilize secretions towards the upper
airways and oral pharynx. To many, IPV is seen as a superior method of
secretion removal compared to traditional chest physical therapy, vibratory therapy and other forms of oscillatory airway clearance. IPV can be utilized on patients via a mouth piece or mask interface, and can also be used inline during mechanical ventilation.
