Dear Healthcare Provider,
You may not have heard of the Vibralung Acoustical Percussor (Vibralung), an airway clearance device which
was FDA 510(k) cleared in May 2014 (K133057). Please let me introduce this safe, gentle and highly-effective
intrapulmonary acoustical airway clearance device, with over 1,200 units in the field.
The Vibralung uses sound waves directly to the airways (via a mouthpiece) in several ways:
Mucus or secretion mobilization
Opening and relaxing inflamed and constricted airways
Helping patients recover from pneumonia, where several doctors have theorized that the Vibralung's random noise helps move fluid from the lungs back into the vascular system.
Anecdotally, a couple of patients were on antibiotics for over 3 weeks, when they added the Vibralung to their treatment regimens. The pneumonia was cleared in the next 2-4 days.
The Vibralung could be a critical adjunct therapy for COVID-19 patients who have developed pneumonia or
other indicated respiratory issues.
The Vibralung consists of a Treatment Control Unit (4. TCU) which is cleared for multi-patient use. It should be
disinfected between patients according to hospital guidelines, such as with an alcohol wipe. The other parts are
cleared for single patient use only and are considered disposable. They are the Hand Held Transducer (1. HHT),
along with the Patient Change Kit (2. mouthpiece assembly), as well as other accessories.
The Vibralung generates sound (acoustical) waves through a transducer. The sound waves are delivered to the
respiratory system via a mouthpiece. The Vibralung generates three tonal frequency stepping modes, Low,
Medium, and High, which are all 10-minute treatments. Low is for larger airways, Medium is for middle
airways, and High is for smaller airways. These overlapping modes collectively cover a range from 55 to 1,200
Hz. During these treatments, at or near sympathetic resonance, the mucus, mucus plugs, and/or the airway
surfaces themselves will vibrate due to sound's oscillatory effect, causing the mucus to break away from the
airway walls, thin out, and liquefy. This makes it easier for the patient to expel.
Another mode called Random Noise appears to help reduce constriction and inflammation of the airways, such
as in asthma, to improve breathing. In the case of pneumonia, the vibrations and random noise appear to help
mobilize the fluids which have accumulated. As has been theorized, this may move the fluids back into the
The Vibralung has a variable expiratory PEP valve, and may optionally be used with the Circulaire II Hybrid
nebulizer or a tracheotomy interface kit.
The Vibralung is indicated for:
Chronic Obstructive Pulmonary Disease (COPD), chronic bronchitis, bronchiectasis, asthma, cystic
fibrosis, pneumonia, neuromuscular respiratory disease, and patients with or at risk of developing

COVID-19 lung complications at this time.

Pneumonia Recommended Usage Directions
For severe pneumonia (such as COVID-19 induced) increase the number of treatments up to 5 per day.
Day 1: L-Low followed by R5 for two to three treatments. If little or no secretions are expelled, move to
M-Medium followed by R5.
Day 2: L-Low followed by R5 mornings and M-Medium followed by R5 mid-day and evening.
If pneumonia appears to be in the lowest lobe or more distal, treat with M-Medium followed by R5 in the mornings and mid-day, then H-High followed by R5 in the evenings.
Continue treatments until symptoms abate.
