## Abstract

A therapy system is operable to deliver at least one respiratory therapy to a patient. For example, therapy system may be operable to deliver any one or more of the following therapies: a high frequency chest wall oscillation (HFCWO) therapy, a positive expiratory pressure (PEP) therapy, a nebulizer therapy, an intermittent positive pressure breathing (IPPB) therapy, a cough assist therapy, a suction therapy, a bronchial dilator therapy, and the like. The therapy system is contained in a housing supported by a mobile stand.

## Claims

### Claim 1

An apparatus to apply high frequency chest wall oscillation (HFCWO) therapy to a thorax of a patient, the apparatus comprising
a garment configured to be worn on the patient's thorax,
a plurality of oscillators coupled to the garment, each oscillator of the plurality of oscillators being configured to be situated over an associated region of a front of the patient's thorax, wherein each oscillator of the plurality of oscillators comprises an inflatable chamber that receives air pulses to produce oscillatory forces against the thorax of the patient by the respective inflatable chamber, and
at least one user input that is usable to adjust at least one operating parameter of at least one oscillator of the plurality of oscillators so that the at least one oscillator operates differently than each of the other oscillators of the plurality of oscillators during delivery of the HFCWO therapy to the patient, wherein the plurality of oscillators comprise a first oscillator configured to be situated over a top portion of the patient's right lung, a second oscillator configured to be situated over a bottom portion of the patient's right lung, a third oscillator configured to be situated over a top portion of the patient's left lung, and a fourth oscillator configured to be situated over a bottom portion of the patient's left lung, and wherein the at least one oscillator comprises at least one of the first oscillator, the second oscillator, the third oscillator, and the fourth oscillator, wherein the at least one user input comprises first, second, third, and fourth user inputs that are separately and individually mounted on the garment and located directly below a respective one of the first oscillator, the second oscillator, the third oscillator, and the fourth oscillator when the patient is wearing the garment having the patient's thorax in an upright position.
