It may also increase positive end expiratory pressure and end-expiratory volume improving oxygenation [22], with low risk of barotrauma and air trapping.
Campbell T, Ferguson N, McKinlay RGC (1986) The use of a simple administered method of positive expiratory pressure (PEP) in chest physiotherapy after abdominal surgery.
1] Possible explanation for increased maximum breathing capacity & expiratory pressure could be regular deep inhalation and exhalation for prolonged period leads to strengthening of respiratory muscles.
Finally, a multiple regression model was proposed to predict the dependence of the values obtained for maximal respiratory pressures respect to the independent variables with better r2 by a linear combination of the parameters used and the theoretical and practical formulation of the model obtained for values of maximum inspiratory and expiratory pressure was exposed.
25%-75%]: maximal mid-expiratory flow rate, MVV: maximum voluntary ventilation, MIP: maximum inspiratory pressure, MEP: maximum expiratory pressure.
Positive expiratory pressure devices can prolong expiratory time and decrease respiratory rate (van der Schans et al 1994), thereby reducing airway closure (Marini et al 1989) and dynamic hyperinflation, and have been used in the management of lung disease in which airway collapse is a problem.
The most frequently described methods of evaluating upper airway collapsibility are the critical pressure measurement (Pcrit) and the negative expiratory pressure (NEP) technique.
Also, higher and more sustained expiratory pressures during both singing and speech help to maintain voice loudness at a relatively constant level (Binazzi, et al.
A hybrid of CPAP/PEEP therapy is BiPAP, a patient triggered, pressure targeted and flow or time cycled form of ventilation, using an inspiratory pressure higher than the expiratory pressure.
When DHD Healthcare was designing its acapella choice vibratory Positive Expiratory Pressure (PEP) system for patients suffering respiratory difficulties, it was faced with various material challenges.
In designing its new vibratory Positive Expiratory Pressure (PEP) system for patients suffering respiratory difficulties, DHD Healthcare worked with specialty compounder RTP Company to develop materials to meet the system's diverse criteria for rigidity, dimensional stability, FDA compliance, and ability to withstand repeated autoclaving, RTP reports.
