What Is The Relationship Between Vibration Of The Chest Wall And The Resulting Chest Wall Forces, Chest Wall Circumference, Intrapleural Pressure, And Expiratory Flow Rate?
Hi Thomas,
You might need to read Dr. Bredge McCarren and the research that is published by this group. You will find answers in these publications.
Group has shown that the expiratory flow rate produced by vibration is approximately equal to the sum of the flow rates due to recoil of the lung and due to the compression and oscillation components of vibration https://pubmed.ncbi.nlm.nih.gov/16515421/ PMID: 16515421
In terms of an intrapleural pressure (IPP), what is proposed is that vibrational forces applied to the chest wall are transmitted to the lungs and airways. Also, that high frequency oscillation component of vibration influences IPP and expiration. An application of vibration during the expiratory phase increases expiratory flow rates PMID: 17132121
These forces increase IPP, which in turn increases expiratory flow rate hence helping to mechanically unload secretions (if you are interested in this).
I am interested how these forces influence hemodynamics. It looks like, they decrease an afterload, if applied during expiration.
Good luck with your studies, hope this helps.
