The Frequencer® provides airway clearance therapy and promotes bronchial drainage by inducing vibration in the chest walls. This device is intended to be a component of chest physiotherapy by providing a convenient method of external thorax manipulation. The Frequencer® is indicated for patients who have respiratory ailments that involve defective mucociliary clearance, as typically seen in patients suffering from cystic fibrosis as well as chronic bronchitis, bronchiectasis, ciliary dyskinesia syndromes, asthma, muscular dystrophy, neuromuscular degenerative disorders, post-operative atelectasis and thoracic wall defects.
For hospitals already acquainted with ultrasound and scanners, which operate at a very high frequency, the Frequencer® generates low frequency within the range of 20-65Hz and offers an adjustable intensity based on the patient's condition. Sound used at low and very low frequencies offers a completely new range of specific and targeted treatment possibilities in airway clearance.
It only takes a few seconds for the patient or therapist to select individual settings and start therapy.
Low frequency greatly reduces mucus viscosity and promote mucus flow.
Many patients, due to their unique or vulnerable condition, may not always be candidates for conventional airway clearance treatments. The Frequencer® provides the RT with the ability to treat the underlying airway clearance condition and provide a solution for these patients.
Daria C. Boffito Study Summary
Influence of frequency and amplitude on the mucus viscoelasticity of the novel mechano-acoustic Frequencer™.
To study a mechano acoustic treatment device to help patients expectorate excess mucus in a non-invasive and enervating way. It was important to understand how the mucus rheology and hydration changes depending on the frequency and amplitude of the acoustic waves delivered to the sample using the Frequencer™.
Study on Mucus_D. C. Boffito, PhD
Influence of frequency and amplitude on the mucus viscoelasticity of the novel mechano acoustic Frequencer™
Background: Cystic fibrosis affects 1/3200 Caucasians. This genetic disease disturbs the ion and water home- ostasis across epithelia, , thus rendering mucus more viscous and harder to expel. Conventional treatments rely on he clapping method coupled with postural drainage. Despite the effectiveness of these procedures, they are invasive and enervating.
White Paper: Acoustic Airway Clearance with the FrequencerTM - Clinical Evidence and Markets
Laura M. McIntosh, Ph.D., April 20, 2020
The prevalence of airway clearance disorders is enormous. In addition to significant quality of
life issues and burden on the health care system, life-threatening situations and death may
arise when the clearance of mucus from airways is ineffective.
Clinical study at UCSD
In an abstract presented at the 2010 AARC meeting in Las Vegas, UCSD (University of California in San Diego), and later published in the Science Journal of the American Association for Respiratory Care, presented results of a non-subsidized study on usage of the Frequencer® and sputum production. The USCD already had in place a protocol identifying the Therapy Vest and the IPV as primary choices and the G5, Flutter and Acapella as secondary options. With their non-subsidized study, they wanted to classify the Frequencer® and its new acoustic technology in airway clearance. Their conclusion was that the Frequencer® "can safely be considered to be one of the preferred or primary choices by the patient and RCP (Repiratory Care Practitioner)."
Study on force applied to the patient's chest
"Because airway clearance often deals with patients already weakened by their condition, the strain associated with the technique used to clear the airways may impact patient condition. This lab study performed by Bruno Tardif, Eng., compares the force applied to a patient's chest by the Frequencer® versus the force applied by the hand of a technician in Chest Physiotherapy (CPT)."
Study on wave depth-of-penetration in the chest
"This Université de Paris study showed that mechanical coupling is much stronger than acoustic coupling on the surface of the chest, but rapidly diminishes in strength with depth of penetration. Conversely, acoustic coupling is weaker at the surface but diminishes less with depth of penetration."
Study with the Frequencer® and CPT
"This study showed that for many CF patients, treatments with the Frequencer® used in a sitting or slightly reclined position were as effective as CPT treatment performed by technicians with the patient in a postural drainage position."
White paper on acoustics and the Frequencer®
"To better understand how acoustics may be used to affect human airway clearance, Marc Bacon, P. Eng., and Dr. André Cantin, MD, share their expertise. Refer to the attached white paper for summaries of studies and mathematical explanations as to how acoustics can have a positive effect on mucus and airway clearance."
Study on the Frequencer® sound level
"This study showed the decibel level of the Frequencer® is about equal to that of human laughter; well below the maximum dB level tolerated by human ears."
