Acapella Vibratory PEP Mucus Clearance Device, 15 Liters by Smiths Medical Acapella Vibratory PEP Mucus Clearance Device


Smiths Medical Portex Acapella Vibratory PEP Therapy System is a Respiratory Therapy used for Breathing Therapy that combines the benefits of PEP therapy and airway vibrates to mobilize pulmonary secretions. Manufactured by Smiths Medical, the Acapella Device can be used sitting down, standing or reclined. Another benefit to PEP therapy and a vibratory valve is that it is much easier to tolerate than Chest Physical Therapy (CPT) and takes half the time of a conventional CPT session. Technically speaking, the valve facilitates the opening of airways in patients with lung disease who have secretory problems such as Chronic Obstructive Pulmonary Disease (COPD), Asthma, or Cystic Fibrosis. The vibratory valve comes with instructions as well on how to operate the unit and optimally use it to your benefit.

Two Options:

There are two color-coded options when using the Acapella mucus clearance apparatus: blue and green. The blue model is low-flow, working less than 15 liters per minute (LPM) for three seconds, and the green model is high flow, working more than 15 LPM for three seconds. If you are unsure which model you are best suited for, we suggest consulting your doctor. Each therapy model is designed based on clinical needs. You can, however, adjust the Acapella valve frequency and flow resistance by adjusting a dial.

Smiths Medical also manufactures a unit that disassembles for cleaning called the Acapella Choice. The Acapella breathing device can be easily cleaned by removing the mouth piece, rinsing with warm soapy water and letting it air dry.
